1. What characteristic best describes a touch screen?

   • an input device that recognizes touch and pressure as instructions
   • an output device used to present information from a laptop onto a screen
   • an output device that uses LED, LCD, or OLED technology
   • a head-mounted device that provides head-motion and eye-tracking sensors and displays three-dimensional images

   • Explanation & Hint: An input device that recognizes touch and pressure as instructions: This is the most accurate description of a touch screen. Touch screens are primarily input devices that allow users to interact with a device (like a smartphone, tablet, or information kiosk) through touch or pressure. This interaction can include tapping, swiping, pinching, or pressing on the screen’s surface. The technology detects the presence and location of a touch, translating these actions into commands or inputs for the device. An output device used to present information from a laptop onto a screen: This description is more suitable for a monitor or display screen, not specifically a touch screen. While touch screens do display information (hence they also function as output devices), their defining characteristic is not just the presentation of information, but their ability to register and respond to touch. Traditional monitors or display screens without touch capabilities would fit this description better. An output device that uses LED, LCD, or OLED technology: This description refers to the technology used for the visual display aspect of screens, including touch screens. LED (Light Emitting Diode), LCD (Liquid Crystal Display), and OLED (Organic Light Emitting Diode) are types of display technologies that can be found in both touch and non-touch screens. While this description is relevant to the display part of a touch screen, it does not encompass the touch-responsive aspect, which is essential to defining a touch screen. A head-mounted device that provides head-motion and eye-tracking sensors and displays three-dimensional images: This description fits virtual reality (VR) headsets or augmented reality (AR) headsets rather than touch screens. VR and AR headsets are worn on the head and often include sensors to track head motion and sometimes eye movement, providing an immersive experience with three-dimensional images. This technology is distinct from touch screens, as it focuses on virtual or augmented environments and typically does not involve direct touch interaction. In summary, while some of these descriptions touch on aspects related to display technology or other types of interactive devices, the first option is the most accurate and specific in describing a touch screen’s primary function as an input device that recognizes touch and pressure.

2. What characteristic best describes a projector?

   • an output device used to present information from a laptop onto a screen

   • Explanation & Hint: The characteristic that best describes a projector is: An output device used to present information from a laptop onto a screen: A projector is fundamentally an output device that takes input from various sources like laptops, media players, or other electronic devices and projects the visual content onto a screen or surface. This makes it ideal for presentations, movies, or educational purposes, where a larger viewable area is required. It translates digital signals into visual content that is then enlarged and displayed. Now, let’s briefly explain why the other options are not suitable for a projector: An output device that uses LED, LCD, or OLED technology: This description is more suitable for describing types of display screens or televisions. While modern projectors can use technologies like LED (Light Emitting Diode) or LCD (Liquid Crystal Display) for image projection, this description alone does not encapsulate the primary function of a projector, which is to project images onto a separate surface. A head-mounted device that provides head-motion and eye-tracking sensors and displays three-dimensional images: This description corresponds to virtual reality (VR) or augmented reality (AR) headsets, not projectors. VR and AR headsets are worn on the head and typically involve immersive experiences with three-dimensional images, often with interactive elements like head-motion and eye-tracking sensors. An input device often used to provide secure access to locations or devices by using voice, facial, or fingerprint recognition: This option describes biometric security systems, which are input devices used for security purposes. They are designed to recognize unique physical characteristics like voice, face, or fingerprints to grant access. This is unrelated to the function of a projector, which is to display visual content on a larger scale. Therefore, the most accurate description of a projector is as an output device used for displaying or presenting visual content from various sources onto a larger surface.

   • Explanation & Hint: The characteristic that best describes an AR (Augmented Reality) headset is: A head-mounted device that superimposes images and audio over a real-world image and can provide users immediate access to information about their real surroundings: AR headsets are designed to overlay digital content (like images, audio, or other sensory enhancements) onto the real world. This technology enhances the user’s perception of reality by adding virtual elements to their physical environment, often in real-time. AR headsets are used in various applications, including gaming, education, and professional fields, to provide an interactive experience that combines the virtual with the real world. Now, let’s look at why the other options do not describe an AR headset: An input device that digitizes an image by placing the document on a flat glass surface and scanning from underneath: This describes a scanner. Scanners are used to convert physical documents or images into digital form by scanning them. This is fundamentally different from AR headsets, which do not digitize physical objects but rather augment the user’s view of the real world with digital information. An input device for playing games and flight simulation applications: While this could partially apply to AR headsets in the context of gaming, it’s more specifically a description of gaming controllers or simulation equipment. AR headsets do facilitate gaming experiences by augmenting reality, but they are not limited to this function and are used for a broader range of applications. A device that allows the use of one set of keyboard, mouse, and monitor to control multiple computers: This describes a KVM switch (Keyboard, Video, Mouse switch). A KVM switch enables the use of a single set of input and output devices to control multiple computers, which is unrelated to the functionality of an AR headset. In summary, an AR headset’s defining characteristic is its ability to augment the real world with digital content, enhancing the user’s environment with overlaid images, audio, and potentially other sensory data.

It is commonly used in situations where a physical signature is required for verification or authorization purposes, such as in package delivery, point-of-sale transactions, or document signing. The signature pad converts the motion and pressure of a pen or stylus into a digital image that represents the handwritten signature. Now, let’s explain why the other options do not describe a signature pad: An input device that digitizes an image by placing the document on a flat glass surface and scanning from underneath: This description fits a scanner, specifically a flatbed scanner. Scanners are used to digitize physical documents or images, but they do not specialize in capturing handwritten signatures like signature pads. An input device for playing games and flight simulation applications: This describes gaming controllers or specialized joysticks used in gaming and simulation contexts. These devices provide interactive control for video games and simulators but are unrelated to the function of a signature pad, which is focused on capturing handwritten signatures. A device that allows the use of one set of keyboard, mouse, and monitor to control multiple computers: This is a description of a KVM switch (Keyboard, Video, Mouse switch). A KVM switch allows a single set of input and output devices to control multiple computers.

When a card is swiped through the reader, it decodes the information contained in the magnetic stripe, which is typically used for processing transactions, verifying identity, or granting access. Now, let’s look at why the other options do not describe a magstripe reader: An input device that digitizes an image by placing the document on a flat glass surface and scanning from underneath: This describes a scanner, particularly a flatbed scanner. Such scanners are used for digitizing physical documents or images by scanning them, which is different from the function of a magstripe reader that reads data from magnetic stripes. An input device for playing games and flight simulation applications: This refers to gaming controllers or flight simulators’ joysticks. These devices are used to interact with and control video games or simulation software. They are not related to the functionality of magstripe readers, which are used for reading encoded data on cards. A device that allows the use of one set of keyboard, mouse, and monitor to control multiple computers: This describes a KVM switch (Keyboard, Video, Mouse switch). A KVM switch is used to control multiple computers using a single set of peripherals (keyboard, mouse, and monitor). This technology is unrelated to magstripe readers, which are focused on reading data from magnetic stripes on cards. In summary, a magstripe reader is best characterized as an input device designed to read and decode information from the magnetic stripes on plastic cards.

18. Refer to the exhibit. Match the type of expansion slot to the letter shown in the graphic. (Not all options are used.)

    

    

    Explanation & Hint: A ==> PCI: This is the older type of expansion slot, typically used for a variety of expansion cards before the advent of PCIe. It’s larger than the PCIe x1 slot and has been a standard for many years. B ==> PCIe x1: This is the smaller expansion slot designed for cards that do not require a lot of bandwidth, like network cards, sound cards, or other interface cards. C ==> PCIe x16: This is the largest slot on the motherboard, typically used for graphics cards (GPUs). It offers the highest bandwidth of these slots, which is necessary for the high data transfer rates required by modern graphics cards. These slots allow for the addition of various functionalities to the computer system by accommodating compatible expansion cards. Each slot type is designed to provide a certain level of data transfer speed, and they are keyed differently to prevent the insertion of incompatible cards. AGP (Accelerated Graphics Port): AGP was developed specifically for video cards. It was widely used from the late 1990s until the mid-2000s. It provided a direct connection between the card and the memory, which allowed for faster processing of complex graphics. AGP slots were designed to deliver faster performance with 3D graphics and video streams. Over time, AGP was phased out in favor of the more versatile and faster PCI Express (PCIe) standard for graphics cards. ISA (Industry Standard Architecture): ISA was an early type of expansion slot used from the early 1980s into the late 1990s. It was initially a 16-bit system, later expanded to 32-bit in the EISA (Extended Industry Standard Architecture) version. ISA slots were used for a wide variety of cards, including modems, sound cards, and network cards. As computer technology evolved, ISA slots became less common due to their limited speed and bandwidth compared to newer standards. MCA (Micro Channel Architecture): MCA was introduced by IBM in the mid-1980s with their PS/2 systems. It was designed to overcome the limitations of ISA by providing a higher bandwidth and greater expansion capabilities. MCA supported plug and play configuration, which allowed the system to automatically configure devices. Despite its technical advantages, MCA was not widely adopted outside of IBM’s own systems due to proprietary issues and competition from the more open and widely supported PCI standard. Each of these architectures was used in different eras of computing and has been largely replaced by newer technologies such as PCI and PCI Express, which offer greater speed, flexibility, and bandwidth.

19. Which connector would be used for a laptop external hard drive?

    • DVI
    • eSATA
    • PATA
    • SATA
    • S/PDIF

    • Explanation & Hint: For connecting an external hard drive to a laptop, the most suitable connector among those listed would be: eSATA (External Serial Advanced Technology Attachment): eSATA is an extension to the SATA interface, tailored for external storage needs. It allows for the connection of external mass storage devices like hard drives while offering the same performance as internal drives. eSATA ports are designed to connect external SATA devices and are capable of fast data transfer rates comparable to internal drives. The other connectors listed have different primary purposes: DVI (Digital Visual Interface): DVI is used to connect a video source, such as a computer, to a display device, like a monitor. It is not used for hard drives. PATA (Parallel Advanced Technology Attachment): PATA, also known as IDE, is an older disk drive interface that was common in desktop and laptop computers before being largely replaced by SATA. External drives with PATA interfaces typically use USB rather than a direct PATA connection because laptops do not have external PATA connectors. SATA (Serial Advanced Technology Attachment): SATA is used for connecting internal hard drives and SSDs in desktop and laptop computers. While SATA itself is for internal connections, the external version is eSATA. S/PDIF (Sony/Philips Digital Interface Format): S/PDIF is an audio interface used to transmit digital audio signals between devices. It is not used for data storage devices like hard drives. Therefore, for an external hard drive, eSATA is the correct choice if both the hard drive and the laptop have eSATA ports. If they do not, external hard drives often use USB connectors (such as USB 3.0 or USB-C) for universal compatibility and convenience.

26. A user has connected a USB 3.0 device to a computer using a 3 ft (1m) USB 3.0 cable. However, instead of an expected data transfer rate of up to 5 Gb/s, the user notes a data transfer rate of no more than 450 Mb/s. What is the most probable reason for this lower than expected data transfer rate?

    • The device was connected to a USB 2.0 port on the computer.
    • The cable used exceeds the maximum length that allows USB 3.0 to transfer data at 5Gb/s.
    • The device was connected to a USB 1.1 port on the computer.
    • The USB 3.0 cable is faulty.
      

      Answers Explanation & Hints: USB 2.0 allows transmission speeds up to 480 Mb/s and USB 1.1 allows transmission rates of up to 12 Mb/s in full-speed mode. A transmission speed of 450 Mb/s would indicate that a USB 2.0 port was used on the computer because USB devices can only transfer data up to the maximum speed allowed by the specific port. The generally accepted maximum length of a USB 3.0 cable is 9.8 ft (3m) which is three times the length of the cable used in this example, so the cable length is acceptable for full USB 3.0 capability. If a USB cable is faulty then no data transfer at all is likely to occur.

27. What transfers heat away from the processor first?

    • cooling fins
    • thermal compound

28. Which design specification criterion is most important when designing a computer that will be a thin client whose applications are accessed from a remote virtual server?

    • amount of RAM
    • amount of local hard drive storage
    • number of processor cores
    • speed of network card

    • Explanation & Hint: When designing a computer that will be a thin client with applications accessed from a remote virtual server, the most important design specification criterion is the: Speed of network card: Thin clients rely heavily on network connectivity to access applications and resources on a remote server. Therefore, having a fast and reliable network card is crucial to ensure that the thin client can communicate with the server quickly and without interruption. The network card’s speed will affect the overall performance of remote applications, as it determines how quickly data can be transmitted between the thin client and the server. The other components, while important in a general sense, are less critical for a thin client setup: Amount of RAM: While sufficient RAM is necessary for running the local operating system and any client-side processes, thin clients typically require less RAM than standard desktop computers because the heavy processing is done on the server side. Amount of local hard drive storage: Local storage is less important for a thin client because the applications and data are stored on the remote server. Thin clients often use minimal local storage or might even boot from a network location. Number of processor cores: The local processing power in a thin client is generally not as critical, since the processing is done on the server. A thin client needs just enough processing power to run the client operating system and handle the user interface for the remote applications. In summary, the speed of the network card is typically the most critical specification for a thin client, as it directly impacts the client’s ability to effectively use remote services and applications.

    • RAID level required
    • requirements for the display screens between thin and thick clients
    • internet connection bandwidth between the main and remote office
      

      Answers Explanation & Hints: Thick clients are standard computers that have their own operating system, applications, and local storage. They are stand-alone systems and all of the processing is performed locally on the computer. On the other hand, thin clients are typically low-end network computers that rely on remote servers to perform all data processing. Thin clients in a remote office will require a reliable, high-bandwidth, internet connection to a server. Typically thin clients do not have any internal storage and have limited local resources.

    • cellular communications
    • Bluetooth
    • wired Ethernet
    • Wi-Fi
      

      Answers Explanation & Hints: Mobile devices connect wirelessly to data networks using either Wi-Fi or a telecommunication provider cellular network. Bluetooth is used to connect to peripherals or other local devices over very short distances. Ethernet is a wired network access technology and is not used by mobile devices. Mobile devices do not typically implement WiMAX technology.

72. A computer technician has successfully returned a laptop to full operation and verified system functionality. Actions the technician performed included modifying the registry and applying patches to the operating systems. What is the next step in the troubleshooting process that the technician should do?

    • Reboot the computer.
    • Document the solution.
    • Consult manufacturer manuals and repair logs.
    • Re-attach and test all peripherals.
      

      Answers Explanation & Hints: The technician is ready to conclude the troubleshooting process by documenting the solution. The manufacturer manuals and repair logs would be consulted to establish a plan of action and resolve the problem before the solution has been applied. Rebooting the computer, and re-attaching and testing all peripherals, would occur during the testing and verification stage after the solution has been implemented.

73. A user notices that there is intermittent wireless connectivity on a laptop that is running a wireless PCI Express Micro card using the wireless 802.11n standard. What should the user do to fix the problem?

    • Replace the PCI Express Micro card with a Mini-PCIe card.
    • Replace the PCI Express Micro card with a Mini-PCI card.
    • Move the laptop to a new location.
    • Replace the OS on the laptop.
      

      Answers Explanation & Hints: In this situation the intermittent loss of wireless connectivity could be due to the distance from the access point or some obstruction in the signal path. Moving to a new location would remedy the problem. Replacing the wireless PCI Express Micro card or replacing the OS will not resolve the problem.

74. A technician connects a new LCD monitor for the first time and finds the display very pixilated. What is a possible solution to this problem?

    • Set the screen to native resolution.
    • Change the monitor video connector from DVI to HDMI.
    • Power cycle the monitor.
    • Set the screen resolution to VGA.
      

      Answers Explanation & Hints: The native screen resolution is the optimum design resolution for the monitor and using this should resolve any display issues. Changing the type of video connector and power cycling the monitor is unlikely to resolve this problem. If the display is pixilated, it is most likely at VGA resolution.

75. A sales representative returns to the office and connects the laptop to an external display device. The display device is powered on, but the laptop image is not showing on the display device. What are two things that should be checked? (Choose two.)

82. What is an advantage of using a printer that is connected to a hardware print server compared with a computer-shared printer?

    • A computer that shares a printer always allows for faster printing of documents.
    • A hardware print server is always available to all users.
    • A computer that shares a printer always prioritizes the printing tasks.
    • A hardware print server will have more memory to store the print job than a computer will have that shares a printer.
      

      Answers Explanation & Hints: A PC sharing a printer is usually running multiple tasks simultaneously besides printing and is therefore slower to process and send documents to the printer. A disadvantage of hardware print servers is that they frequently contain less storage space for the print queue compared with a dedicated print server or a computer-shared printer.

83. A technician wants to allow many computers to print to the same printer, but does not want to affect the performance of the computers. What will the technician do to achieve this?

    • Use a software print server.
    • Use a computer-shared printer.
    • Use a hardware print server.
    • Install a second printer.
      

      Answers Explanation & Hints: A hardware print server allows many users to print to the same printer without using the resources of any computer. A computer-shared printer uses a computer to manage all of the print jobs. There is no software print server. Installing a second printer would reduce the print jobs on any one computer, but would still use computer resources.

84. A user is reporting that an inkjet printer is printing colors different from what the printer should be printing. The printer has separate cartridges for each color and the user changed the cyan cartridge recently. What is the action that could fix the problem?

    • Perform a printer head cleaning.
    • Check for loose printer cables.
    • Use a different type of paper.
    • Purchase a maintenance kit.
      

      Answers Explanation & Hints: A head cleaning routine is needed if the cartridges get clogged or if they are new. Typically, inkjet printers print different colors if one of the cartridges is not able to function properly.

85. Which two field replaceable units could be found in a laser printer maintenance kit? (Choose two.)

    • fuser assembly
    • pickup rollers
    • power supply
    • paper trays
    • drum
    • toner cartridge
      

      Answers Explanation & Hints: Usually, manufacturers include in the maintenance kits the parts that are subject to wear. Such parts could be a fuser assembly, transfer rollers, separation pads, and pickup rollers. Power supplies, and drum and paper trays are considered replacement parts that are changed at the time of failure, whereas the toner cartridge is considered a consumable.

86. What is best used to clean the heating element on a thermal printer?

    • mild solvent
    • soap foam
    • isopropyl alcohol
    • distilled water

    • Determine the exact cause.
    • Verify system functionality.
    • Document the findings.
      

      Answers Explanation & Hints: What the technician just did was to determine the exact cause. What is next in the troubleshooting process is to establish a plan of action.

88. A user reports that a laser printer is printing shadow images and letters. Which part should the technician replace to correct this problem?

    • network cable
    • pick up roller
    • drum
    • fuser
      

      Answers Explanation & Hints: The drum is a metal cylinder that holds an electrostatic charge to pick up the toner powder. If the drum is defective, then the charge on the cylinder will not hold the correct latent image to attract the toner.

89. A technician is called to work on a laser printer that prints vertical lines on every printed page. Which laser printer part should be checked first?

    • pickup rollers
    • RAM
    • toner cartridge
    • wiper blade
      

      Answers Explanation & Hints: A vertical line could be a sign of a faulty drum or a problem with the toner cartridge. The toner cartridge is the easiest one to test if it is faulty and can be reused later if it turns out to not be the problem.

90. A technician is called to troubleshoot a problem where a user claims that none of the print jobs from this morning have printed. The technician sees that there is only one printer installed in the device list and it is a network printer shared with other users. What should the technician check?

    • the print queue
    • the IP address of the printer
    • the fuser assembly
    • the user rights to the printer
      

      Answers Explanation & Hints: A networked printer might have a backed up print queue caused by the printer being offline, out of paper, or a paper jam. There might also be a document stuck in the print queue causing all of the others after it to not print. Check the printer for any issues first then check the print queue and see if sending a different document to the top of the queue or canceling the document at the top of the queue frees up the printer.

91. A user reports that a “Document failed to print” message appears every time the network printer is restarted. What could be a cause of the problem?

    • The fuser is faulty.
    • The IP address on the printer is statically assigned.
    • The user rights to the printer have been configured incorrectly.
    • The IP address assigned to the printer is a duplicate IP address.
      

      Answers Explanation & Hints: Networked printers are commonly assigned a static IP address. A DHCP reservation can be made and the MAC address of the printer can be entered at the DHCP server so that the printer receives the same IP address each time, or a technician can just manually enter an IP address into the printer. Each device must have a unique IP address, and a duplicate one would cause a network printer to not function.

92. What are two functions of hypervisors? (Choose two.)

    • to partition the hard drive to run virtual machines
    • to protect the host from malware infection from the virtual machines
    • to manage virtual machines
    • to allocate physical system resources to virtual machines
    • to share the antivirus software across the virtual machines
      

      Answers Explanation & Hints: The hypervisor does not protect the hosting OS from malware. Neither does it allow sharing software across virtual machines. The hard drive of the supporting computer does not need to be partitioned to run virtual machines. The hypervisor creates and manages virtual machines on a host computer and allocates physical system resources to them.

93. A computer technician is asked to configure a workstation with two virtual machines. What would be the purpose of the configuration?

    • to have redundancy in case of hard drive failure
    • to increase the performance of the computer
    • to have two separate operating systems running at the same time on one computer
    • to allow multiple applications, that require more RAM than is installed, to be active simultaneously
      

      Answers Explanation & Hints: In the process of virtualization, virtual machines are created. Different operating systems can be installed on each virtual machine without interfering with one another.

94. A computer technician creates a virtual environment. Which security measure should the technician take for the virtual machine running Windows 10, if any?

    • Each virtual machine should have antivirus software installed.
    • Because each virtual machine contains an operating system that is different from what is on the host computer, no security software is needed.
    • A hardware firewall should be placed between each virtual machine and the internet or it will be necessary to ensure that the Windows firewall is enabled on each virtual machine.
    • The virtual machine must use the same secure passwords as the host computer uses.
      

      Answers Explanation & Hints: Virtual machines are susceptible to the same security threats that a host computer is. All security measures that are recommended for a computer in a home or business environment should also be taken within the virtual environment.

      Answers Explanation & Hints: With measured service of the Cloud model, the resource usage can be easily monitored, controlled, reported, and billed to provide full visibility to both the Cloud service provider and customers.

100. A company uses cloud services and is setting up a new switch supplied by the cloud provider. Which cloud model is used by the company?

     • DaaS
     • IaaS
     • PaaS
     • SaaS
       

       Answers Explanation & Hints: Whenever a company has an infrastructure device like a router or switch in the company cloud solution, the cloud model being used is IaaS.

101. A company owns servers for a particular corporate application. The servers are housed in an external data center. The company has an agreement with a cloud provider to spin up additional servers for the same application during peak usage. Which cloud model is the company using?

     • community
     • hybrid
     • private
     • public
       

       Answers Explanation & Hints: A private cloud is a cloud-based service where the company manages the devices or applications within the cloud. They are just located away from the business at a provider site. If a company is using a public cloud, a provider manages the devices or the applications or both for the company. A hybrid cloud is a combination of two types of clouds, and a common practice is a private and public cloud combination.

102. What is meant by a cloud service being metered?

     • The company is charged a monthly or annual fee for a specific service.
     • The company is charged based on the amount of service used.
     • The company is allowed unlimited access to a service during specific periods of time.
     • A special device is attached to the demarcation point where the service provider network ends and the company network starts.
       

       Answers Explanation & Hints: An unmetered cloud service is one where the service is free or it is charged on a monthly or annual basis. A metered cloud service has the charge based on how much the service is used. A company can also have an unmetered service up to a particular point and then the company is assessed additional charges based on how much additional services the company used.

103. A company has a few employees that are designers. The designers do not have the CAD application loaded on their local computer. Instead, the designers use a CAD application hosted by the application developer. Which type of virtualization is the company using?

     • DaaS
     • IaaS
     • PaaS
     • SaaS
       

       Answers Explanation & Hints: Software as a Service (SaaS) is a cloud computing type that provides access to one or more applications through a server. This server is not owned or managed by the company using the application.

104. A Windows 10 computer has several printers configured in the Control Panel Devices and Printers window. Which printer will the computer choose to be the first option for printing?

     • the printer that is set as the default printer
     • the software-based printer that is used to create PDF files
     • the software-based printer that is used to create XPS files
     • a manual selection, which is always needed
       

       Answers Explanation & Hints: The Default Printer option is set globally and will be the first printer to print a job unless another printer is selected in a Per-Document manner. Software-based printers are just instances of different kinds of printers, but to be chosen to do the job, they will need to be selected as a default or Per-Document printer. Selecting a printer every time a printing job sends is not needed.

105. What problems can be resolved by implementing QoS and traffic engineering protocols in an enterprise VoIP network?

     • excessive latency and jitter
     • unexpected infrastructure disruptions
     • excessive noise and interference
     • the inability to transfer calls
       

       Answers Explanation & Hints: Deploying QoS (Quality of Service) and traffic engineering protocols on an enterprise network can resolve problems of excessive latency (data transmission delay) and jitter (excessive variation in delay). Unexpected infrastructure disruptions, excessive noise and interference, and the inability to transfer calls are IP telephony configuration or physical layer problems that the deployment of QoS and traffic engineering protocols cannot resolve.

106. Which two devices commonly make use of Power over Ethernet (PoE)? (Choose two.)

     • IP phones
     • wireless access points
     • network printers
     • network storage devices
     • wireless speakers
       

       Answers Explanation & Hints: IP phones and wireless access points commonly use Power over Ethernet (PoE). Network printers and storage devices typically use externally connected power sources such as electrical outlets or USBs. Wireless speakers use a battery power source.

107. Which network device is used to ensure that each server, providing the same service on a network, is used as much as the others on that network?

     • load balancer
     • router
     • client
     • wireless access point
       

       Answers Explanation & Hints: Specifically, a load balancer is used to ensure that each server providing the same service on a network is used as much as the others on that network. A router routes data between different networks. Client is the term used to describe hosts (end devices) on a network that accesses servers. A wireless access point enables hosts to connect to a wireless network.

108. A technician is building a gaming computer with a PCIex16 graphics card. The graphics card requires 100 watts of power to run. How will this power be supplied?

     • from the PCIe slot on the motherboard, together with a separate PCIe power connector from the power supply
     • from the PCIe power connector from the power supply
       

       Answers Explanation & Hints: PCIe can supply up to 25 watts of power to each slot. A graphics card can supply up to 75 watts. For potent graphics cards, an additional 75 watts can be supplied by a PCIe power connector from the power supply.

109. Match the Wi-Fi standard with the maximum supported speed.

     

     Explanation & Hint: 802.11n: This standard, also known as Wi-Fi 4, can reach speeds of up to 600 Mbps. 802.11ad: This Wi-Fi standard is known for its very high-speed potential, reaching up to 7 Gbps. It operates in the 60 GHz frequency band. 802.11ax: Also known as Wi-Fi 6, is the successor to 802.11ac and can achieve higher speeds, often quoted up to 9.608 Gbps under optimal conditions. 802.11ac: This standard, also known as Wi-Fi 5, increased the maximum speed over its predecessors to a range that often tops out around 1.3 Gbps, but with advancements and multiple streams, it can theoretically reach over 6.933 Gbps. 802.11a: This is an older standard that typically had a maximum throughput of 54 Mbps, but it is not listed among the options you’ve provided. With the given options, the correct matches would be: 802.11n with 600 Mbps 802.11ad with 7 Gbps 802.11ax with 9.608 Gbps 802.11ac likely corresponds to the speed closest to its theoretical maximum, but none of the provided speeds match the typical top speeds of 802.11ac. If we were to choose the closest one, it might be 6.933 Gbps, assuming advanced configurations. 802.11a it would align with 40 Mbps if that were an option.

110. While a user is working on a spreadsheet, the computer reboots. What are two components that could cause this issue? (Choose two.)

     • CPU
     • power supply
     • ROM
     • BIOS
     • wireless NIC
     • RAID

     • Explanation & Hint: If a computer unexpectedly reboots while a user is working on a spreadsheet, the issue could be related to hardware or software problems. However, focusing on the hardware components listed: Power Supply: A failing or inadequate power supply can cause the computer to restart without warning. If the power supply is unable to provide a steady and sufficient amount of power to the system components, it can lead to sudden reboots. CPU: The Central Processing Unit (CPU) is less likely to be the cause of random reboots compared to the power supply. However, if the CPU is overheating due to a malfunctioning fan or poor thermal paste application, it could trigger the system’s protective measure to reboot to prevent damage. The other components listed are less likely to cause a computer to reboot: ROM (Read-Only Memory): ROM is non-volatile memory that is typically used to store firmware. While ROM errors can cause a system to fail to boot, they are less likely to cause a system to reboot unexpectedly. BIOS (Basic Input/Output System): The BIOS firmware initializes and tests hardware at startup. A BIOS issue might prevent the computer from booting, but it’s not a common cause of random reboots once the system is running. Wireless NIC (Network Interface Controller): While driver issues with a wireless NIC can potentially cause system instability, they are unlikely to cause the system to reboot entirely. It’s more likely to lead to connectivity issues. RAID (Redundant Array of Independent Disks): Problems with RAID could potentially cause data access issues or system instability, but random reboots are not a typical symptom unless there is a major fault with the RAID controller hardware. Thus, the most likely culprits for the computer rebooting unexpectedly would be the power supply and potentially the CPU, especially if it’s related to overheating.

111. While a user is working on a spreadsheet, the computer reboots. What are two components that could cause this issue? (Choose two.)

     • CPU
     • power supply
     • motherboard
     • BIOS
     • wireless NIC
     • RAID

     • Explanation & Hint: If a computer reboots unexpectedly while a user is working on a spreadsheet, the two components from the list that could be the cause of such an issue are indeed: CPU: If the CPU is overheating, it may cause the computer to reboot in an attempt to prevent damage. Overheating can occur due to a malfunctioning fan, degraded thermal paste, blocked airways, or a heavy processing load that exceeds the cooling system’s capabilities. Power Supply: An unstable or failing power supply can also cause the computer to reboot. If the power supply is unable to provide consistent power due to internal faults, degradation, or external power fluctuations, the computer may restart unexpectedly. These components are critical to the system’s operation, and issues with either can result in the computer restarting to protect itself from potential damage. When diagnosing such issues, it is common to check the system’s temperature and power supply health, among other things.

112. After continuous morning use, a computer suddenly reboots without the intervention of the user. What are the two most likely hardware parts that could cause this problem? (Choose two.)

     • CPU
     • power supply
     • hard drive
     • wireless NIC
     • ROM
     • BIOS

     • Explanation & Hint: If a computer suddenly reboots without user intervention, especially after being used for a continuous period, it often suggests an issue with hardware components that are prone to overheating or power issues. The two most likely hardware parts that could cause this problem are: CPU: The Central Processing Unit (CPU) can overheat due to sustained use, especially if there is insufficient cooling, such as a malfunctioning fan, clogged heatsink, or degraded thermal paste. Overheating can trigger safety mechanisms that reboot the computer to prevent damage to the processor. Power Supply: The Power Supply Unit (PSU) can cause reboots if it becomes unstable or fails. This could be due to overheating, a fault within the PSU, or inadequate power being delivered to the system’s components. While other listed components might cause system issues, they are less likely to cause a computer to reboot: Hard Drive: A failing hard drive would typically cause data access issues, system freezes, or crashes rather than a reboot. Wireless NIC: Network Interface Cards, even if they fail or encounter issues, are more likely to cause loss of network connectivity, not a system reboot. ROM: Read-Only Memory in the context of computer hardware usually refers to the memory that stores the BIOS/UEFI firmware. Problems with ROM could potentially prevent booting but are less likely to cause mid-use reboots. BIOS: The Basic Input/Output System is firmware that initializes the computer hardware during the boot process. A BIOS error could prevent a computer from starting up or cause instability, but it’s a less common cause of spontaneous reboots during operation. Given the scenario described, issues with the CPU and power supply are the more probable causes of the unexpected reboot.

113. After continuous morning use, a computer suddenly reboots without the intervention of the user. What are the two most likely hardware parts that could cause this problem? (Choose two.)

     • CPU
     • power supply
     • display port or display
     • BIOS
     • wireless NIC
     • RAID

     • Explanation & Hint: When a computer reboots on its own after being used for a while, it typically points to issues related to overheating or power supply problems. Based on the hardware parts listed, the two most likely to cause such a problem are: CPU: The CPU is susceptible to overheating, especially after continuous use. If the cooling system is not functioning properly or if the CPU is under a heavy load, it may overheat. Modern CPUs have built-in thermal protection that will shut down or reboot the computer to prevent damage when they reach a critical temperature. Power Supply: The power supply unit (PSU) provides power to all the components of the computer. If the PSU is failing or if it’s not providing a consistent power supply due to issues like overheating, voltage fluctuations, or defects, it can cause the computer to reboot. The other components listed are less likely to cause a computer to reboot: Display Port or Display: While a malfunctioning display or port can cause screen issues, they typically do not trigger a system reboot. BIOS: The BIOS firmware is responsible for booting up the computer. Although a corrupt BIOS can cause boot issues, it’s not usually the cause of a spontaneous reboot during normal operation. Wireless NIC: A network interface controller is unlikely to cause a system reboot. At most, a defective NIC might lead to network connectivity issues. RAID: A Redundant Array of Independent Disks is used for data storage and redundancy. Faults in RAID may lead to data access issues or system crashes, but spontaneous reboots are not commonly directly caused by RAID issues. Therefore, the CPU and the power supply are the most likely culprits in this scenario.

114. After continuous morning use, a computer suddenly reboots without the intervention of the user. What are the two most likely hardware parts that could cause this problem? (Choose two.)

     • CPU

     • wireless NIC
     • RAID

     • Explanation & Hint: In the scenario where a computer reboots suddenly after being used for a continuous period in the morning, the two most likely hardware causes are: CPU: The CPU is central to the computer’s operations and is susceptible to overheating, particularly if it’s been under a sustained heavy load or if there is a problem with its cooling system (like a failed fan or degraded thermal compound). Overheating can cause the system to shut down or reboot unexpectedly to prevent damage. Power Supply: The power supply unit (PSU) is critical for providing stable power to the computer. If the PSU is faulty, overheating, or failing, it can lead to irregular power delivery, which may cause the system to reboot. Additionally, if the PSU cannot cope with the energy demands of the system, this might also lead to sudden reboots. While a surge strip could also be a factor if it’s faulty or if there was a power surge, it is less of a component of the computer and more of an accessory for power management. However, if the surge strip fails or triggers due to a surge, it could cut off power to the computer, causing it to reboot. The BIOS (Basic Input/Output System) is less likely to cause reboots once the system has successfully started up. Problems with the BIOS more typically prevent the computer from booting at all or cause issues during the boot process. A wireless NIC (Network Interface Controller) generally wouldn’t cause the system to reboot. Issues with a wireless NIC would typically lead to network connectivity problems. Problems with RAID (Redundant Array of Independent Disks) configurations usually result in data access issues or storage-related errors, not typically in sudden system reboots. Given the options, the CPU and power supply are the most probable hardware parts that could cause the computer to reboot unexpectedly. If including external factors, a surge strip could also be considered, especially if the reboot coincides with power fluctuations.

115. A technician has been called in to investigate a problem with the computer rebooting randomly throughout the day. What two pieces of hardware could cause this problem? (Choose two.)

     • CPU
     • power supply
     • surge strip
     • BIOS
     • wireless NIC
     • RAID

     • Explanation & Hint: Random reboots can be caused by a few different hardware issues. If a technician is investigating random reboots, they would likely consider the following two hardware components as potential causes: Power Supply: A failing power supply can cause random reboots. This could be due to it overheating, having inconsistent power output, or experiencing power surges that disrupt the normal flow of electricity to the computer’s components. CPU: Overheating or malfunctioning of the CPU can lead to random reboots. The CPU has a thermal protection feature that will shut down the system to prevent damage if it gets too hot. This could be due to a cooling system that isn’t working properly (e.g., a failed fan or dried-out thermal paste). The other pieces of hardware listed are generally less likely to cause random reboots: Surge Strip: While a faulty surge strip can cause power interruptions, it would typically cut power entirely rather than just reboot the computer. However, it’s still a possibility if the surge strip is poorly regulating the power or if it’s faulty and causes brief interruptions in power. BIOS: Issues with the BIOS can cause boot problems or system instability, but they are less likely to cause random reboots once the system has successfully started up. Wireless NIC: A network interface card, unless it’s causing a system-level conflict or has a severe driver issue, typically doesn’t cause reboots. Network problems usually manifest as connectivity issues. RAID: While RAID controller issues can lead to data loss or corruption, they generally do not cause the system to reboot. If there is a major fault with the RAID controller hardware, it could potentially lead to system instability, but this is less common. Therefore, the two most likely suspects in such a situation would be the power supply and the CPU, especially in the context of hardware-related problems.

116. For two days in a row, a user has noticed that the computer reboots several times before it eventually starts. What are two suspect components? (Choose two.)

     • CPU
     • power supply
     • BIOS
     • motherboard
     • ROM
     • wireless NIC

     • Explanation & Hint: If a computer is rebooting several times before starting up, and considering the CPU and power supply as the two suspect components: CPU: If the CPU is malfunctioning or overheating, it can cause the system to reboot multiple times. Overheating can happen if the CPU’s cooling system (heatsink and fan) is not functioning properly, if there is a build-up of dust blocking airflow, or if the thermal paste between the CPU and heatsink has degraded and is not conducting heat effectively. Additionally, if there is an issue with the CPU’s power delivery or with the CPU itself, it could cause instability that leads to multiple reboots. Power Supply: The power supply is a critical component that, if failing, can cause the computer to reboot. This might be due to power fluctuations, overheating within the PSU itself, or problems with the electrical supply from the outlet. A PSU that’s on the verge of failure may struggle to provide the consistent power required to keep the system running, especially during the power-intensive boot-up phase. When diagnosing such issues, a technician would likely start by checking these two components. They might monitor the CPU temperature, check the condition of the thermal paste, ensure that the cooling system is working correctly, and test the power supply unit’s output to ensure it’s providing stable and sufficient power. If either the CPU or the power supply is found to be faulty, it would need to be repaired or replaced to resolve the rebooting issue.

117. While a user is working on a spreadsheet, the computer reboots. What are two components that could cause this issue? (Choose two.)

     • CPU
     • power supply
     • ROM
     • motherboard
     • wireless NIC
     • BIOS

     • Explanation & Hint: If a computer reboots unexpectedly while a user is working on a spreadsheet, the two components from the list that could be the cause of such an issue are indeed: CPU: If the CPU is overheating, it may cause the computer to reboot in an attempt to prevent damage. Overheating can occur due to a malfunctioning fan, degraded thermal paste, blocked airways, or a heavy processing load that exceeds the cooling system’s capabilities. Power Supply: An unstable or failing power supply can also cause the computer to reboot. If the power supply is unable to provide consistent power due to internal faults, degradation, or external power fluctuations, the computer may restart unexpectedly. These components are critical to the system’s operation, and issues with either can result in the computer restarting to protect itself from potential damage. When diagnosing such issues, it is common to check the system’s temperature and power supply health, among other things.

118. While a user is working on a spreadsheet, the computer reboots. What are two components that could cause this issue? (Choose two.)

     • CPU
     • power supply
     • motherboard
     • display port or display
     • surge strip
     • hard drive

     • Explanation & Hint: If a computer reboots unexpectedly while a user is working on a spreadsheet, the two components from the list that could be the cause of such an issue are indeed: CPU: If the CPU is overheating, it may cause the computer to reboot in an attempt to prevent damage. Overheating can occur due to a malfunctioning fan, degraded thermal paste, blocked airways, or a heavy processing load that exceeds the cooling system’s capabilities. Power Supply: An unstable or failing power supply can also cause the computer to reboot. If the power supply is unable to provide consistent power due to internal faults, degradation, or external power fluctuations, the computer may restart unexpectedly. These components are critical to the system’s operation, and issues with either can result in the computer restarting to protect itself from potential damage. When diagnosing such issues, it is common to check the system’s temperature and power supply health, among other things.

119. After continuous morning use, a computer suddenly reboots without the intervention of the user. What are the two most likely hardware parts that could cause this problem? (Choose two.)

     • CPU
     • power supply
     • hard drive
     • surge strip
     • RAID
     • display port or display

     • Explanation & Hint: In the scenario where a computer suddenly reboots after continuous use in the morning, the two most likely hardware causes are: CPU: The Central Processing Unit (CPU) is a critical component, and if it overheats, it can cause the computer to reboot. Overheating may occur due to a malfunctioning cooling system (like a failed fan or degraded thermal paste), blocked airways, or a heavy processing load. Modern CPUs have built-in thermal protection that will shut down or reboot the computer to prevent damage when reaching critical temperatures. Power Supply: The Power Supply Unit (PSU) provides electrical power to the computer. If it’s failing or not providing stable power due to issues like overheating, internal component failure, or inadequate wattage, it can lead to irregular power delivery, causing the computer to reboot. The other components listed are generally less likely to cause random reboots: Hard Drive: A failing hard drive can cause data access issues, system freezes, or crashes, but it’s less likely to cause the system to reboot on its own. Surge Strip: If a surge strip is failing or if there’s a power surge, it might cut off power to the computer. However, this usually results in a power loss rather than a reboot. RAID (Redundant Array of Independent Disks): Issues with RAID can lead to data loss or system crashes but are not typically associated with causing random reboots. Display Port or Display: Display issues can cause screen errors or loss of visual output but do not usually result in a system reboot. Considering these options, the CPU and the power supply are the most probable hardware parts that could cause the computer to reboot unexpectedly.

120. A technician is setting up a server that requires two connections between the client and the server, one for commands and replies, the other for the actual transfer of files. What type of server will accomplish this task?

     • FTP server
     • print server
     • DNS server
     • web server

     • Explanation & Hint: The type of server that requires two connections between the client and the server, one for commands and replies and the other for the actual transfer of files, is an FTP server (File Transfer Protocol server). Here’s a brief overview of why the other server types don’t fit this description: Print Server: A print server manages print requests and network-connected printers. It typically does not use two separate connections for commands and data transfer as described. DNS Server (Domain Name System server): A DNS server translates domain names into IP addresses. It does not require two separate connections for command and data transfer. Web Server: A web server hosts and serves web pages. It primarily uses HTTP or HTTPS protocols, which do not inherently require two separate connections for commands and file transfers. FTP, on the other hand, specifically uses two distinct network connections in its standard mode of operation: one for sending control commands (like login credentials and commands to change directories or list files) and another for the actual transfer of files. This is a distinctive feature of the FTP protocol.

121. A network analyst is setting up a server that uses a store-and-forward method of sending, storing, and retrieving electronic messages across a network. What type of server is the analyst setting up?

     • email server
     • FTP server
     • print server
     • web server

     • Explanation & Hint: The network analyst is setting up an Email Server. An email server uses a store-and-forward method to handle electronic messages. This process involves receiving emails, storing them, and then forwarding them to the intended recipient when they are available to receive the email. This type of server manages the sending, receiving, and storing of email messages over a network. To clarify why the other options do not fit this description: FTP Server (File Transfer Protocol server): An FTP server is used for the storage and transfer of files between systems, but it does not use a store-and-forward method. It is primarily for direct file transfers. Print Server: A print server manages the printing process within a network, handling print jobs sent to networked printers. It does not use store-and-forward for emails or messages. Web Server: A web server hosts and serves web content (like websites). It does not handle emails or use a store-and-forward method for messages. Email servers uniquely fit the description of using a store-and-forward method for handling electronic messages.

122. A manager works remotely and needs to access classified information on the web servers within the company head office. What type of server uses the secure HTTP (HTTPS) for exchanging text, graphic images, sound, and video on the web.

     • web server
     • print server
     • DNS server
     • FTP server

     • Explanation & Hint: The type of server that the manager would need to access classified information securely, using HTTPS (Secure HTTP) for exchanging text, graphic images, sound, and video on the web, is a Web Server. HTTPS is an extension of the Hypertext Transfer Protocol (HTTP) with added security capabilities. It is used for secure communication over a computer network within a web browser, ensuring that the data exchanged between the browser and the server is encrypted and secure. This is particularly important for transferring sensitive or classified information, as in the scenario you described. Here’s a brief overview of the other server types: Print Server: A print server manages print requests within a network, handling the connections to printers. It does not use HTTPS as it is not involved in web-based data exchange. DNS Server (Domain Name System server): A DNS server translates domain names into IP addresses. While it is a crucial component of web browsing, it does not itself host or serve web content and does not use HTTPS for secure transactions. FTP Server (File Transfer Protocol server): An FTP server is used for storing and transferring files. While there is a secure version known as FTPS (FTP Secure), this is different from HTTPS and is typically used for file transfers rather than viewing web content. In the context of your scenario, a web server using HTTPS is the appropriate choice for securely accessing and exchanging various types of web content, including classified information.

123. A network administrator in a corporate headquarters office is setting up a new laptop for a new employee. What type of service will provide an IP address for the new device?

     • DHCP
     • FTP server
     • print server
     • web server

     • Explanation & Hint: The service that will provide an IP address for the new laptop in a corporate environment is DHCP (Dynamic Host Configuration Protocol). DHCP is a network management protocol used on IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network, so they can communicate with other IP networks. This automates and centrally manages the assignment of IP addresses, subnet masks, gateway, and other network settings. The other services mentioned serve different purposes: FTP Server (File Transfer Protocol server): An FTP server is used for the storage and transfer of files. It does not assign IP addresses. Print Server: A print server manages networked printers and print jobs but does not handle the assignment of IP addresses. Web Server: A web server hosts and serves web content and also does not play a role in assigning IP addresses to devices on the network. Therefore, for the task of automatically assigning an IP address to a new device on the network, DHCP is the correct service.

124. A technician is setting up an environment where popular and frequently accessed web pages are stored locally on the internal network. What type of server will accomplish this task?

     • proxy server
     • print server
     • DNS server
     • FTP server

     • Explanation & Hint: The technician is setting up a Proxy Server to accomplish the task of storing popular and frequently accessed web pages locally on the internal network. A proxy server acts as an intermediary between end users and the internet. It can cache (store) frequently accessed web pages and resources. When a user requests a web page that has been previously accessed, the proxy server can provide the cached version quickly, without needing to retrieve it from the internet again. This can improve access speed and reduce bandwidth usage. The other server types serve different purposes: Print Server: Manages networked printers and print jobs. It is not involved in caching or serving web content. DNS Server (Domain Name System server): Translates domain names into IP addresses, facilitating the finding of websites on the internet. It does not cache web content. FTP Server (File Transfer Protocol server): Used for the transfer and storage of files between systems, typically not used for caching web content. Therefore, for caching and serving frequently accessed web content locally, a proxy server is the appropriate choice.

125. A technician is setting up an environment where popular and frequently accessed web pages are stored locally on the internal network. What type of server will accomplish this task?

     • proxy server
     • DHCP
     • DNS server
     • print server

     • Explanation & Hint: In this scenario, the technician is setting up a server environment to store popular and frequently accessed web pages locally on the internal network. The type of server that will accomplish this task is a Proxy Server. A proxy server acts as an intermediary between users and the internet. It can cache (store) web pages and other online content locally. When a user requests a web page, the proxy server first checks if it has a stored (cached) version of this page. If it does, the proxy server provides the page from its cache, speeding up the access time and reducing bandwidth usage. This is particularly useful for frequently accessed websites in an organization, as it improves efficiency and load times. The other options serve different purposes: DHCP (Dynamic Host Configuration Protocol): DHCP servers assign IP addresses to devices on a network. They do not store or cache web content. DNS Server (Domain Name System server): A DNS server translates domain names (like www.example.com) into IP addresses. It does not cache web content but helps in resolving domain names to their respective IP addresses. Print Server: A print server manages print requests within a network and controls networked printers. It has no functionality related to storing or caching web content. Hence, for the described requirement, a proxy server is the most suitable type of server.

126. A user needs to connect to Cisco.com but does not know the IP address for this website. What type of server will translate the website name into an IP address?

     • DNS server
     • DHCP
     • print server
     • FTP server

     • Explanation & Hint: The type of server that translates a website name, like “Cisco.com,” into an IP address is a DNS (Domain Name System) server. DNS servers are responsible for converting human-readable domain names into the numerical IP addresses that computers use to identify each other on the network. Here’s a brief overview of the other server types mentioned: DHCP (Dynamic Host Configuration Protocol) Server: This server automatically assigns IP addresses and other network configurations to devices on a network, but it doesn’t translate domain names to IP addresses. Print Server: A print server manages one or more printers in a network, allowing multiple computers to share these printers. It doesn’t have a role in translating domain names. FTP (File Transfer Protocol) Server: An FTP server is used for the storage and transfer of files over a network. Like a print server, it does not translate domain names to IP addresses.

127. An administrator is setting up a framework to support access control on a network device. What type of server is able to control those who are permitted to access a network and track what actions they perform while accessing the network?

     • authentication server
     • DHCP
     • DNS server
     • print server

     • Explanation & Hint: For setting up a framework to control who is permitted to access a network and to track their actions while accessing the network, an Authentication Server would be the most appropriate choice. An authentication server is a type of server used to verify the identity of users by validating their credentials before they access a network resource. It can also keep track of user activities, providing an audit trail of their actions while on the network. This is essential for maintaining network security and for compliance with various regulatory standards. To briefly describe the other server types: DHCP (Dynamic Host Configuration Protocol) Server: Assigns IP addresses and other network configurations to devices on a network. It doesn’t handle user authentication or activity tracking. DNS (Domain Name System) Server: Translates domain names into IP addresses. It doesn’t involve user authentication or monitoring their activities. Print Server: Manages printers and print jobs in a network environment. It has no role in network access control or user activity tracking.

128. A company is setting up one new laser printer on every floor. What type of server will store the print jobs in a queue and then spool them to the device when it is ready?

     • print server
     • DHCP
     • DNS server
     • FTP server

     • Explanation & Hint: The type of server that will store the print jobs in a queue and then spool them to the device when it’s ready is a Print Server. A print server’s primary function is to manage one or more printers in a network. It receives print jobs from client computers and sends these jobs to the appropriate printer, managing the print queue to ensure that documents are printed in the order they were received. This is particularly useful in an environment like a company with multiple printers, as it helps in efficient management and distribution of print jobs. The other server types mentioned have different functions: DHCP (Dynamic Host Configuration Protocol) Server: Assigns IP addresses and other network configurations to devices on a network, but doesn’t manage print jobs. DNS (Domain Name System) Server: Translates domain names into IP addresses, and isn’t involved in managing printers or print jobs. FTP (File Transfer Protocol) Server: Used for the transfer of files over a network but does not handle print jobs or printer management.

129. What network service controls those who are permitted to access a network, what they can do while they are there, and track what actions they perform while accessing the network?

     • AAA
     • DHCP
     • DNS server
     • print server

     • Explanation & Hint: The network service that controls who is permitted to access a network, what they can do while they are there, and tracks what actions they perform while accessing the network is AAA (Authentication, Authorization, and Accounting). Authentication: Verifies the identity of a user or device attempting to access the network. Authorization: Determines what an authenticated user or device is permitted to do on the network. Accounting: Keeps track of what actions the user or device performs while on the network. The other services mentioned have different functions: DHCP (Dynamic Host Configuration Protocol): Assigns IP addresses and other network configurations to devices on a network, but doesn’t manage user access or track activities. DNS (Domain Name System) Server: Translates domain names into IP addresses, and is not involved in user access control or activity tracking. Print Server: Manages printers and print jobs in a network, unrelated to network access control or user activity monitoring.

     • Explanation & Hint: When an office assistant in a law firm encounters “memory overload” error messages while printing large legal documents, the most appropriate steps to resolve this issue include: Add More Memory to the Printer: This is likely the most direct solution to a memory overload issue. Printers have their own RAM to process documents for printing. When a document is too large for the printer’s current memory capacity, it can result in a memory overload error. Increasing the printer’s memory can allow it to handle larger documents more effectively. Update the Printer’s Firmware: While not listed in these options, this is often a relevant step. Firmware updates can sometimes improve the efficiency of how a printer uses its memory, potentially resolving memory overload issues. Reduce the Document’s Size or Print in Smaller Batches: If adding memory is not an option, another workaround is to reduce the size of the document being printed, or to print the document in smaller batches. This can be less demanding on the printer’s memory. Connect the Printer Using Wireless: This might not directly solve a memory issue, but if the memory overload is related to a data transmission bottleneck when connected via a cable (which is less common), switching to a wireless connection might help. However, this is less likely to be effective if the issue is truly due to insufficient memory in the printer itself. The other options you mentioned, such as replacing the pickup roller, updating the BIOS, and updating the OS, are less likely to be relevant for a memory overload issue in a printer. The pickup roller is related to the physical picking and feeding of paper, not memory. BIOS and OS updates are more related to the computer or server that is sending the print job, not the printer’s ability to handle large documents.

     • Update the OS.
     • Connect the printer using wireless.

     • Explanation & Hint: When a reporter is experiencing extremely slow printing with high-resolution photographs on a color laser printer, there are several potential solutions to consider: Add More RAM to the Printer: This is a viable solution if the slowness is due to the printer’s inability to process large files quickly. High-resolution photos require more memory to process than standard documents. Upgrading the printer’s RAM can significantly improve its ability to handle these large files more efficiently. Update the Printer’s Firmware or Driver: While not listed in these options, updating the printer’s firmware or the driver on the computer can often resolve performance issues. Manufacturers frequently release updates to improve the functionality and efficiency of their printers. Optimize the Print Settings: Before considering hardware changes, it’s wise to check the print settings. Printing high-resolution photos in the highest quality mode can be very slow. Adjusting the settings to a slightly lower quality or opting for draft mode can speed up the process without significantly impacting the output quality for certain uses. Check the Network Connection: If the printer is networked, a slow or unstable network connection can cause delays. Switching from a wired to a wireless connection, or vice versa, can sometimes improve the situation, especially if the current connection is problematic. However, this is more of a trial-and-error approach. Inspect for Hardware Issues: While replacing the pickup roller won’t typically resolve issues with slow printing of high-resolution photos, it’s a good practice to ensure that all hardware components of the printer are functioning correctly. A general maintenance check can sometimes uncover hidden issues that affect performance. The other options you mentioned, such as updating the BIOS and updating the OS, are less directly related to the printer’s performance issues. The BIOS and OS updates pertain more to the computer or server sending the print jobs, and are unlikely to impact the speed of the printer itself unless there are specific compatibility issues or driver problems.

150. A receptionist is complaining about the following printer issue: The print queue seems to be functioning properly, but the printer does not print. What are two possible causes of this issue? (Choose two.)

     • There is a bad cable connection.
     • The printer has an error such as out of paper, out of toner, or paper jam.
     • The print queue is overloaded.
     • The printer does not have enough RAM.
     • The printer lid has not been closed securely.

     • Explanation & Hint: For the issue described where the print queue seems to be functioning properly, but the printer does not print, two possible causes could be: There is a Bad Cable Connection: This is a common issue that can disrupt communication between the computer and the printer. If the cable connection is loose, damaged, or not properly connected, the printer might appear ready in the print queue but fail to receive or process the print command. Checking and securing the cable connections, or replacing a faulty cable, can resolve this issue. The Printer has an Error such as Out of Paper, Out of Toner, or Paper Jam: Printers often fail to start printing if there are operational issues like being out of paper, out of toner, or having a paper jam. These errors might not always be communicated back to the print queue on the computer, leading to a situation where the job appears ready to print but the printer remains inactive. Checking the printer for these common issues and resolving them (by adding paper, replacing toner, or clearing a jam) can solve the problem. The other options, such as an overloaded print queue or the printer not having enough RAM, are less likely in this scenario given the symptoms described. An overloaded print queue would generally slow down printing rather than completely stop it. Insufficient RAM in the printer typically affects the printer’s ability to handle large or complex documents, not its ability to start a print job. The printer lid not being closed securely could be a potential issue, but it’s generally less common and would typically trigger an error or warning message on the printer itself.

151. A photographer is complaining about the following printer issue: The printer issues a “Document failed to print” message. What are two possible causes of this issue? (Choose two.)

     • A cable is loose or disconnected.
     • The printer is no longer shared.
     • The paper tray is flimsy.
     • The print queue is overloaded.
     • The printer lid has not been closed securely.

     • Explanation & Hint: A cable is loose or disconnected: This is a common and straightforward issue. If the connection between the printer and the computer (or network) is not secure due to a loose or disconnected cable, it can prevent the printer from receiving print jobs. Ensuring all cables are properly connected is an essential step in troubleshooting printer issues. The printer is no longer shared: In a network environment, especially in offices or shared spaces, printers are often set up as shared devices. If the printer sharing settings are altered or if the printer is somehow removed from the network sharing options, it could lead to an inability to print, especially from other computers on the network. Restoring the printer’s shared status or ensuring that network sharing settings are correctly configured can resolve this issue. These two causes are indeed plausible and can be relatively common in different printing environments. Checking and addressing both can help in resolving the printing issue.

152. A reporter is complaining about the following printer issue: The paper jams when the printer is printing. What are two possible causes of this issue? (Choose two.)

     • The printer could be dirty.
     • The humidity could be high and that causes the paper to stick together.
     • The laser printer is emitting too much radiation.
     • The printer does not have enough RAM.
     • The print queue is overloaded.

     • Explanation & Hint: When a reporter experiences paper jams while printing, two possible causes for this issue could be: The Printer Could Be Dirty: Over time, dust and debris can accumulate inside a printer, leading to paper jams. The presence of dirt or foreign objects can obstruct the paper’s path, causing it to jam as it moves through the printer. Regular cleaning and maintenance of the printer can help prevent such issues. The Humidity Could Be High and That Causes the Paper to Stick Together: High levels of humidity can affect the condition of the paper. In humid conditions, paper can absorb moisture from the air, causing sheets to stick together. This makes it more likely for multiple sheets to be fed through the printer at once, leading to jams. Using a dehumidifier in the room or storing paper in a dry, cool place can mitigate this problem. The other options listed are less likely to be the cause of paper jams. Radiation from a laser printer is not a factor in causing paper jams. Similarly, insufficient RAM in the printer or an overloaded print queue typically affects the printer’s ability to process and handle print jobs efficiently, but these factors do not directly cause physical paper jams.

153. A manager is complaining about the following printer issue: The printer is printing incorrect colors. What are two possible causes of this issue? (Choose two.)

     • The print heads might need to be cleaned and calibrated.
     • An incorrect cartridge could be installed.
     • The printer is using the wrong cable.
     • The print queue is overloaded.
     • The printer lid has not been closed securely.

     • Explanation & Hint: When a manager encounters an issue with their printer printing incorrect colors, two possible causes could be: The Print Heads Might Need to Be Cleaned and Calibrated: This is a common issue in printers, especially those that use inkjet technology. Over time, print heads can become clogged with ink or dust, leading to poor color output. Additionally, if the print heads are misaligned, it can also result in inaccurate color reproduction. Cleaning and calibrating the print heads can often resolve these issues and improve color accuracy. An Incorrect Cartridge Could Be Installed: Using the wrong type of ink or toner cartridge can lead to incorrect colors being printed. This can happen if a cartridge is incompatible with the printer model or if a color cartridge is placed in the wrong slot. Ensuring that the correct cartridges are installed and properly seated can solve this problem. The other options, such as using the wrong cable, the print queue being overloaded, or the printer lid not being closed securely, are less likely to cause an issue with incorrect colors. The type of cable used generally does not affect color output, and an overloaded print queue would typically lead to delays in printing rather than color inaccuracies. Similarly, an unsecured printer lid might cause other operational issues but is unlikely to directly result in incorrect color printing.

154. A technician is complaining about the following printer issue: The print appears faded on the paper. What are two possible causes of this issue? (Choose two.)

     • The toner cartridge is low.
     • The paper might be incompatible with the printer.
     • The wrong printer type has been selected.
     • The printer does not have enough RAM.
     • The print queue is overloaded.

     • Explanation & Hint: When a technician encounters an issue with print appearing faded on paper, two likely causes could be: The Toner Cartridge is Low: This is a common reason for faded prints, especially in laser printers. When toner levels are low, the printer can’t apply enough toner to the paper, resulting in a faded appearance. Replacing or refilling the toner cartridge is a straightforward solution to this problem. The Paper Might be Incompatible with the Printer: Using the wrong type of paper for the specific printer can affect print quality. Some printers are optimized for certain types of paper, and using a different kind might not absorb or hold the ink or toner properly, leading to faded prints. Switching to a compatible paper type as recommended by the printer manufacturer can improve print quality. The other options, such as the wrong printer type being selected, the printer not having enough RAM, or the print queue being overloaded, are less likely to cause faded prints. Selecting the wrong printer type might affect print layout or formatting but typically does not result in faded prints. Insufficient printer RAM and an overloaded print queue generally affect the printer’s ability to process and manage print jobs efficiently, but they do not directly impact the intensity of the print on the paper.

155. A librarian is complaining about the following printer issue: The printer control panel displays no image. What are two possible causes of this issue? (Choose two.)

     • The contrast of the screen may be set too low.
     • The printer is not turned on.
     • The room temperature is above normal.
     • The print queue is overloaded.
     • The printer lid has not been closed securely.

     • Explanation & Hint: When a librarian is facing an issue where the printer control panel displays no image, two possible causes could be: The Contrast of the Screen May Be Set Too Low: If the contrast setting on the printer’s control panel is too low, it might make the display appear blank or very faint. Adjusting the contrast settings to increase visibility can resolve this issue if the display is otherwise functioning properly. The Printer is Not Turned On: This may seem basic, but it’s a common oversight. If the printer is not properly powered on, the control panel will not display any image. Ensuring that the printer is connected to a power source and turned on is a fundamental step to resolve this issue. The other options, such as the room temperature being above normal, the print queue being overloaded, or the printer lid not being closed securely, are less likely to cause an issue with the printer control panel display. Room temperature typically affects the printer’s internal mechanics rather than its electronic display. An overloaded print queue might delay printing or cause operational errors, but it wouldn’t impact the display on the control panel. Similarly, an unsecured printer lid might trigger an error message or halt printer operations, but it’s unlikely to affect the control panel display directly.

156. A teacher is complaining about the following printer issue: The paper is creased after printing. What are two possible causes of this issue? (Choose two.)

     • The paper-feed tray might not be firmly adjusted against the edges of the printer.
     • The paper might be loaded incorrectly.
     • Print jobs are being sent to the wrong printer.
     • The wrong printer type has been selected.
     • The laser printer is emitting too much radiation.

     • Explanation & Hint: When a teacher experiences the issue of paper being creased after printing, two possible causes could be: The Paper-Feed Tray Might Not Be Firmly Adjusted Against the Edges of the Printer: If the paper-feed tray is not properly aligned or adjusted, it can cause the paper to feed into the printer at an angle or inconsistently. This misalignment can lead to the paper being creased as it moves through the printer. Adjusting the tray to ensure it is snug against the edges of the printer and that paper is aligned correctly can help prevent this issue. The Paper Might Be Loaded Incorrectly: Loading paper improperly into the printer’s tray can also cause creasing. This includes overfilling the tray, using paper that is bent or curled, or not aligning the paper correctly in the tray. Ensuring that the paper is loaded properly, without any pre-existing creases or curls, and in accordance with the printer’s guidelines, can reduce the occurrence of this issue. The other options, such as print jobs being sent to the wrong printer, the wrong printer type being selected, or the laser printer emitting too much radiation, are not likely to be relevant to the issue of paper creasing. Sending jobs to the wrong printer or selecting the wrong printer type would typically affect where and how the document is printed, but not the physical condition of the paper. The concept of a laser printer emitting “too much radiation” is a misconception and is not associated with paper creasing. Laser printers use laser technology to transfer toner to paper, which does not involve harmful levels of radiation.

157. A receptionist is complaining about the following printer issue: The print queue seems to be functioning properly, but the printer does not print. What are two possible causes of this issue? (Choose two.)

     • There is a bad cable connection.
     • The printer has an error such as out of paper, out of toner, or paper jam.
     • The print queue is overloaded.
     • A test page was never printed.
     • The wrong printer type has been selected.

     • Explanation & Hint: When a receptionist encounters an issue where the print queue seems to be functioning properly, but the printer does not print, two possible causes could be: There is a Bad Cable Connection: A faulty or disconnected cable can disrupt the communication between the computer and the printer. Even if the print queue on the computer appears to be functioning normally, a bad cable connection can prevent the printer from receiving the print commands. Checking and ensuring a secure and functional cable connection or replacing a damaged cable can resolve this issue. The Printer has an Error such as Out of Paper, Out of Toner, or Paper Jam: These are common printer errors that can halt printing operations. The printer might display these errors on its control panel or through indicator lights. If the printer is out of paper or toner, or if there is a paper jam, it will not be able to complete the print job despite the queue appearing normal. Resolving these issues (by adding paper, replacing toner, or clearing a jam) can enable the printer to start printing again. The other options, such as the print queue being overloaded, a test page never being printed, or the wrong printer type being selected, are less likely to be the direct cause of the printer not printing in this scenario. An overloaded print queue might slow down printing but typically doesn’t stop it completely. A test page not being printed would not affect subsequent print jobs. Selecting the wrong printer type could cause format or compatibility issues, but it wouldn’t usually result in the printer not printing at all if it’s correctly connected and operational.

158. A photographer is complaining about the following printer issue: The paper is not being fed into the printer. What are two possible causes of this issue? (Choose two.)

     • The paper may be wrinkled.
     • The printer could be set to print to a different paper size than is currently loaded.
     • The paper tray is flimsy.
     • A test page was never printed.
     • The wrong printer type has been selected.

     • Explanation & Hint: When a photographer experiences an issue with paper not being fed into the printer, two possible causes could be: The Paper May Be Wrinkled: Wrinkled or curled paper can cause feed issues in printers. If the paper is not flat or has any physical deformities, it might not be picked up properly by the printer’s rollers. Using smooth, flat paper that is free from wrinkles can help prevent this issue. The Printer Could Be Set to Print to a Different Paper Size Than Is Currently Loaded: If the printer settings specify a different paper size than the size actually loaded in the tray, it can lead to feeding problems. The printer might attempt to feed paper from a tray or a slot that isn’t loaded with the correct size, resulting in no paper being fed for printing. Ensuring that the printer settings match the actual paper size loaded in the printer can resolve this problem. The other options, such as the paper tray being flimsy, a test page never being printed, or the wrong printer type being selected, are less likely to directly cause the issue of paper not being fed into the printer. A flimsy paper tray might affect the stability of the paper but generally does not prevent it from being fed into the printer. The absence of a test page printout would not impact the printer’s ability to feed paper. Selecting the wrong printer type in the printer settings might cause formatting issues or print errors but typically doesn’t result in a failure to feed paper.

159. A reporter is complaining about the following printer issue: The printer is printing unknown characters. What are two possible causes of this issue? (Choose two.)

     • The wrong or an outdated printer driver is installed.
     • The printer has a loose connection.
     • The laser printer is emitting too much radiation.
     • A test page was never printed.
     • The wrong printer type has been selected.

     • Explanation & Hint: In the scenario where a printer is producing unknown characters, the two most plausible causes are: The Wrong or an Outdated Printer Driver is Installed: This is a common cause of printing issues. Printer drivers facilitate communication between the computer and the printer. If the driver is incorrect or outdated, it can lead to miscommunication, resulting in the printer outputting unknown or garbled characters. Updating or reinstalling the correct printer driver can often resolve this issue. The Printer has a Loose Connection: A loose or faulty connection between the printer and the computer can lead to intermittent or incorrect data transmission. This can manifest as the printer printing unknown characters because it is not receiving the correct information from the computer. Checking and securing all cables, or even replacing them if they are damaged, can help fix this problem. It’s important to address both software (driver) and hardware (connection) aspects when troubleshooting printer issues like this.

160. While a technician is installing a printer, the technician hears a loud clicking noise. Which device should the technician check first?

     • hard drive
     • RAM
     • optical drive
     • monitor

     • Explanation & Hint: If a technician hears a loud clicking noise while installing a printer, the first device to check would typically be the hard drive. Clicking noises are often associated with hard drives, especially when they encounter read/write errors or mechanical failures. This is commonly referred to as the “click of death” and can be a sign of a failing hard drive. The other components listed (RAM, optical drive, monitor) are less likely to produce a clicking noise. RAM does not have moving parts, so it wouldn’t make a clicking sound. An optical drive could make a noise when reading a disc, but it’s usually more of a whirring or spinning sound rather than clicking. Monitors do not have moving parts either and are unlikely to produce such noises. Therefore, investigating the hard drive should be the initial step when addressing the clicking noise issue during printer installation.

161. While a technician is installing a printer, the technician hears a loud clicking noise. Which device should the technician check first?

     • hard drive
     • sound card
     • optical drive
     • monitor

     • Explanation & Hint: If a technician hears a loud clicking noise while installing a printer, the device they should check first is the optical drive. This recommendation is based on the context of the situation – installing a printer. It’s possible that the installation involves the use of a CD or DVD for printer drivers or software, and if the optical drive is in use during this process, it could make clicking noises if there is an issue with the disc (like scratches or dirt) or a mechanical problem with the drive itself. While hard drives can also make clicking noises, these are usually associated with more serious issues like the “click of death,” indicating hard drive failure. However, in the context of printer installation, the hard drive is less likely to suddenly exhibit this kind of problem. The sound card and monitor are unlikely to be sources of a clicking noise. Sound cards typically produce electronic sounds or noise, not mechanical clicking, and monitors don’t have moving parts that would cause such a noise.

162. While working in a computer training room, the technician notices that one computer emits a loud clicking noise. Which device should the technician check first?

     • hard drive
     • sound card
     • optical drive
     • monitor

     • Explanation & Hint: When a technician notices a loud clicking noise coming from a computer in a training room, the first device to check should be the hard drive. Clicking noises coming from a computer are often associated with hard drives, especially when they encounter read/write errors or mechanical failures. This is commonly referred to as the “click of death” and can be a sign of a failing hard drive. Hard drives have moving parts (like the read/write head and spinning platters), and a clicking sound could indicate that these parts are malfunctioning. This issue should be addressed promptly, as it could lead to data loss. The other devices listed are less likely to produce a clicking noise: Sound Card: A sound card typically wouldn’t produce a mechanical clicking noise. Issues with sound cards usually manifest as problems with audio output, like distortion or no sound at all. Optical Drive: While an optical drive could potentially make a clicking noise when reading a disc, this would only occur if a disc is in use. If the noise is constant and not related to disc usage, the optical drive is less likely to be the cause. Monitor: Monitors, especially modern LCD/LED types, do not have moving parts and are unlikely to produce a clicking noise. Noise from monitors would be unusual and more likely electronic in nature if it occurs. Given these considerations, investigating the hard drive should be the initial step in resolving the issue of the clicking noise in the computer.

163. While working in a computer training room, the technician notices that one computer emits a loud clicking noise. Which device should the technician check first?

     • hard drive
     • internal speaker
     • optical drive
     • monitor

     • Explanation & Hint: When a technician notices a loud clicking noise coming from a computer in a training room, the first device to check should be the hard drive. Clicking noises from a computer are commonly associated with hard drive issues. These noises can indicate mechanical failures or read/write errors, often referred to as the “click of death,” which could be a sign of a failing hard drive. Hard drives have mechanical components like read/write heads and spinning platters, and problems with these parts can produce clicking sounds. While the other components listed might also produce sounds, they are less likely to produce a clicking noise: Internal Speaker: While the internal speaker can produce various sounds, a consistent clicking noise is unlikely to originate from it unless specifically produced by the system’s audio output, which is rare in normal operation. Optical Drive: An optical drive might make clicking noises, but this is typically only when reading or writing to a disc. If no disc is being used, or if the noise is continuous and not obviously tied to disc activity, the optical drive is less likely to be the cause. Monitor: Monitors, especially newer ones, do not have moving parts and thus are unlikely to produce mechanical clicking noises. Any noise from a monitor would be unusual and more likely to be electronic in nature if it occurs. Therefore, the hard drive is the most likely culprit for a clicking noise in a computer and should be the first component to check.

164. While working in a computer training room, the technician notices that one computer emits a loud clicking noise. Which device should the technician check first?

     • hard drive
     • internal speaker
     • motherboard
     • CPU fan

     • Explanation & Hint: When a technician hears a loud clicking noise from a computer in a training room, the first device to check should be the hard drive. This is because clicking noises are commonly associated with hard drive issues, such as mechanical failures or read/write errors. These noises can indicate significant problems, often referred to as the “click of death,” suggesting a potential failure of the hard drive. Other components listed are less likely to produce a clicking noise: Internal Speaker: The internal speaker in a computer usually doesn’t produce a clicking sound unless it’s being driven by a specific audio signal. It’s not a common source of mechanical noises. Motherboard: While the motherboard is a central component, it doesn’t have moving parts that would produce a clicking sound. Issues with the motherboard typically manifest as system errors or failures to boot, not as audible clicking. CPU Fan: Although fans can make noises, these are usually more of a whirring or buzzing sound rather than a distinct clicking. However, if the fan is hitting something or is severely unbalanced, it might produce a clicking noise. After checking the hard drive, if no issue is found, the CPU fan could be a secondary item to inspect. Considering these possibilities, the hard drive is the most likely source of a loud clicking noise in a computer and should be examined first.

165. Every time a user turns on the computer in the morning, the user hears a loud clicking noise. Which device should the technician check first?

     • hard drive
     • internal speaker
     • motherboard
     • CPU fan

     • Explanation & Hint: When a user hears a loud clicking noise every time they turn on their computer, the first device a technician should check is the hard drive. Clicking noises from a computer are commonly associated with hard drive issues, particularly mechanical failures or read/write errors. This type of noise, often referred to as the “click of death,” can indicate a significant problem with the hard drive, such as the failure of the read/write head or spindle motor. The other components listed are less likely to be the source of a clicking noise: Internal Speaker: It’s unlikely for the internal speaker to produce a clicking noise unless it’s being driven by specific audio signals, which is uncommon during the startup process. Motherboard: The motherboard itself doesn’t have moving parts that would produce a mechanical clicking sound. Issues with motherboards typically manifest in other ways, such as failure to boot or system errors. CPU Fan: While fans can sometimes make noises, these are usually more of a whirring or buzzing sound rather than a distinct clicking. However, if a fan blade is hitting an obstruction or if there’s a bearing issue, it could produce a clicking sound. This is less common compared to hard drive issues but could be a secondary check if the hard drive is not the culprit. Given these considerations, the hard drive should be the primary focus of the technician’s initial investigation.

166. Every time a user turns on the computer in the morning, the user hears a loud clicking noise. Which device should the technician check first?

     • hard drive
     • optical drive
     • CPU fan
     • CPU

     • Explanation & Hint: When a user reports hearing a loud clicking noise every time they turn on their computer, the first device a technician should check is the hard drive. Clicking noises emanating from a computer are often associated with hard drive issues, especially mechanical failures or read/write errors. This kind of noise, sometimes referred to as the “click of death,” can indicate a significant problem with the hard drive’s mechanical components, like the read/write head or the spindle motor. The other components listed, while they can produce noises, have characteristics that are different from a clicking sound: Optical Drive: An optical drive can make clicking noises, but this is typically only when a disc is being read or written to. If the noise occurs every time the computer is turned on, regardless of whether a disc is in the drive, it’s less likely to be the cause. CPU Fan: CPU fans can make a variety of noises, especially if they are malfunctioning or if something is obstructing the fan blades. While a fan issue can sometimes sound like clicking, it’s usually more of a whirring or buzzing sound. CPU: The CPU itself does not make noise, as it lacks moving parts. Any noise directly associated with the CPU would more likely be related to its cooling system, such as the CPU fan. Given these points, the hard drive is the most probable source of the clicking noise and should be examined first.

167. When a co-worker steps into another office, the co-worker notices that the computer is making a loud clicking noise and asks about it. The technician is contacted to investigate. Which device should the technician check first?

     • hard drive
     • monitor
     • CPU fan
     • CPU

     • Explanation & Hint: When a computer emits a loud clicking noise, the first device a technician should check is the hard drive. This is because a clicking sound often indicates a problem with the hard drive, commonly known as the “click of death.” This noise can be a sign of mechanical failure within the hard drive, which might lead to data loss. While other components like the CPU fan or the CPU itself could potentially make unusual noises, these are usually more like whirring or buzzing sounds rather than clicking. The monitor is unlikely to make such a noise unless it’s related to its internal electronics, which is less common compared to hard drive issues. Therefore, the technician should start by examining the hard drive to diagnose the issue accurately and take appropriate action.

168. When a user turns on a workstation, the screen displays an “Invalid Boot Disk” error. The user calls the help desk. Which device should the technician check first?

     • hard drive
     • power supply
     • CPU fan
     • CPU

     • Explanation & Hint: When a user encounters an “Invalid Boot Disk” error upon turning on a workstation, the first device a technician should check is the hard drive. This error typically indicates that the system is unable to find a bootable operating system, which is usually stored on the hard drive. The problem could be due to various issues with the hard drive, such as a failure, disconnection, corruption of system files, or incorrect boot order in the BIOS settings. The power supply is less likely to be the cause of this specific error. While a failing power supply can cause a range of issues, it wouldn’t typically result in an “Invalid Boot Disk” message. Similarly, the CPU fan and the CPU are not the primary suspects for this error. Issues with the CPU or its cooling fan might prevent the computer from booting, but they wouldn’t usually cause an “Invalid Boot Disk” message to appear. Therefore, the technician should start by checking the hard drive to ensure it is properly connected, functioning, and configured as the primary boot device in the system’s BIOS or UEFI settings.

169. When a user turns on a workstation, the screen displays an “Invalid Boot Disk” error. The user calls the help desk. Which device should the technician check first?

     • hard drive
     • motherboard
     • CPU fan
     • CPU

     • Explanation & Hint: When a user encounters an “Invalid Boot Disk” error upon turning on a workstation, the first device a technician should check is the hard drive. This error typically indicates that the system is unable to find a bootable operating system, which is usually stored on the hard drive. The problem could be due to various issues with the hard drive, such as a failure, disconnection, corruption of system files, or incorrect boot order in the BIOS settings. The motherboard could be a secondary point of investigation, particularly if there are reasons to suspect a broader hardware failure or issues with the BIOS settings. However, motherboard issues would typically manifest in more generalized boot failures or system instability, not specifically an “Invalid Boot Disk” error. The CPU fan and the CPU are less likely to be the cause of this specific error. While problems with the CPU or its cooling fan might prevent the computer from booting entirely, they generally wouldn’t cause an “Invalid Boot Disk” message to appear. Therefore, the technician should start by checking the hard drive to ensure it is properly connected, functioning, and configured as the primary boot device in the system’s BIOS or UEFI settings.

170. A user reports that a drive is no longer there. The technician asks the user to demonstrate the problem. Within the application, the user demonstrates that the drive, that was present in the save options yesterday, is now no longer an option. What should the technician do to see if the drive is recognized by the operating system?

     • Use Device Manager.
     • Check the Startup folder.
     • Bring up a command prompt and type ipconfig.
     • Swap the data cables of the mechanical drive and the SSD.

     • Explanation & Hint: To determine if the drive is recognized by the operating system, the technician should use Device Manager. Device Manager in Windows is a system utility that lists all the hardware devices installed on the computer. It can be used to check if the drive is being detected by the operating system and if there are any issues with the drivers or the device itself. Here’s why the other options are less appropriate: Check the Startup folder: This action is not relevant to the problem. The Startup folder contains programs that run on system startup, and it wouldn’t provide information about the presence or status of a drive. Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used to display network configuration details and is not related to checking the status of storage drives. Swap the data cables of the mechanical drive and the SSD: While this could be a step in troubleshooting hardware connection issues, it’s more invasive and should be considered only after confirming that the drive is not recognized by the operating system through less intrusive methods like checking Device Manager. Therefore, the first step should be to open Device Manager and look under the “Disk drives” section to see if the missing drive is listed. If it is not listed, the technician might then consider physical troubleshooting steps like checking connections or swapping cables.

171. A computer has two mechanical hard drives. The second drive (D:) is used for data storage. When trying to save an email attachment to the local hard drive, the user notices that the D: drive is not an option. What should the technician do to see if the drive is recognized by the operating system?

     • Use File Explorer.
     • Bring up a command prompt and type ipconfig.
     • Open a web browser and type the following: http://127.0.0.1. Verify if both drives appear in the list.
     • Swap the data cables of the mechanical drive and the SSD.

     • Explanation & Hint: To check if the D: drive (the second mechanical hard drive) is recognized by the operating system, the technician should use File Explorer. File Explorer in Windows is a user-friendly tool that allows users to view and manage files and drives on their computer. By using File Explorer, the technician can quickly verify whether the D: drive is visible to the operating system and accessible. Here’s why the other options are less appropriate: Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used for displaying network configuration details and has no relevance to checking the status of storage drives. Open a web browser and type the following: http://127.0.0.1: This address is a loopback address for the local machine, typically used for network testing. It would not provide information about the local storage drives. Swap the data cables of the mechanical drive and the SSD: This hardware troubleshooting step should be considered only after confirming through software means (like using File Explorer) that the drive is not recognized. Swapping cables is more invasive and should be a later step in the troubleshooting process. Therefore, the technician should start by opening File Explorer to see if the D: drive is listed under “This PC” or “Computer.” If the drive is not visible there, further troubleshooting steps, including checking disk management, examining physical connections, or swapping cables, may be necessary.

172. A user reports that a drive is no longer there. The technician asks the user to demonstrate the problem. Within the application, the user demonstrates that the drive, that was present in the save options yesterday, is now no longer an option. What should the technician do to see if the drive is recognized by the operating system?

     • Use Device Manager.
     • Boot into UEFI/BIOS and see if the drive appears.
     • Open a web browser and type the following: http://127.0.0.1. Verify if both drives appear in the list.
     • Bring up a command prompt and type ipconfig.

     • Explanation & Hint: To determine if the drive is recognized by the operating system after a user reports that it is no longer visible in the save options of an application, the technician should take the following steps: Use Device Manager: This is a good initial step. Device Manager shows all the hardware components of the system, including storage drives. If the drive is not listed in Device Manager, it suggests that the operating system is not recognizing it, which could be due to a hardware issue or a driver problem. Boot into UEFI/BIOS and see if the drive appears: This is another important step if the drive is not visible in Device Manager. Checking the UEFI/BIOS will determine if the drive is recognized at the hardware level. If the drive is not detected in the UEFI/BIOS, it suggests a more fundamental hardware issue, such as a disconnected or failed drive. The other options are not relevant to the problem: Open a web browser and type the following: http://127.0.0.1: This action would not provide any useful information regarding the status of local storage drives. The address 127.0.0.1 is the loopback address used for network testing and does not relate to local drive configuration. Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used to display network configuration and is not relevant to checking the status of storage drives. Therefore, the technician should start with Device Manager to see if the drive is recognized by the operating system, and if not, proceed to check the UEFI/BIOS settings.

173. A laptop has an NVMe drive (C:) and a mechanical hard drive (D:). When the user tries to save a spreadsheet to the D: drive, the user notices that the D: drive is not there. What should the technician do to see if the drive is recognized by the operating system?

     • Use the Disk Management Control Panel.
     • Open a web browser and type the following: http://127.0.0.1. Verify if both drives appear in the list.
     • Bring up a command prompt and type ipconfig.
     • Swap the data cables of the mechanical drive and the SSD.

     • Explanation & Hint: To determine if the D: drive (mechanical hard drive) is recognized by the operating system on a laptop with both an NVMe drive (C:) and a mechanical hard drive, the technician should use the Disk Management Control Panel. Disk Management is a Windows utility that provides a detailed view of all connected storage devices, their partitions, and statuses. It can be used to verify whether the D: drive is visible to the operating system and to manage drive partitions. Here’s why the other options are less appropriate: Open a web browser and type the following: http://127.0.0.1: This action is not useful for this issue. The address 127.0.0.1 is a loopback address for network testing and is not related to local storage drive configuration. Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used for displaying network configuration information and is irrelevant to checking the status of storage drives. Swap the data cables of the mechanical drive and the SSD: This is not typically applicable to laptops, as their internal drives often use different connectors (NVMe drives use a dedicated slot, while mechanical drives use a SATA connection) and are not as easily swappable as in desktops. Moreover, physical troubleshooting like this should only be considered after confirming the drive’s status through software diagnostics. Therefore, the technician should open the Disk Management tool (which can be accessed by right-clicking on “This PC” or “My Computer” and selecting “Manage,” then navigating to “Disk Management”) to see if the D: drive is listed and in a healthy state. If the drive is not visible in Disk Management, further hardware diagnostics or a physical inspection might be necessary.

174. A computer has an SSD for the operating system and applications and uses another mechanical hard drive for data storage. The user reports that data can no longer be saved to the mechanical hard drive. What should the technician do to see if the drive is recognized by the operating system?

     • Use Device Manager.
     • Remove the drive and attach it to the SATA port used by the SSD. Reboot the computer and see if the drive is recognized.
     • Open a web browser and type the following: http://127.0.0.1. Verify if both drives appear in the list.
     • Bring up a command prompt and type ipconfig.

     • Explanation & Hint: To check if the mechanical hard drive is recognized by the operating system in a computer that uses an SSD for the operating system and applications, and a mechanical hard drive for data storage, the technician should: Use Device Manager: This is the first step to take. Device Manager in Windows provides a comprehensive list of all hardware devices installed, including storage drives. By opening Device Manager, the technician can quickly see if the mechanical hard drive is recognized by the operating system. If the drive is not listed, it may indicate a problem with the drive’s connection, failure, or an issue with the drivers. The other options provided are less suitable for the initial diagnosis: Remove the drive and attach it to the SATA port used by the SSD: This is a more advanced troubleshooting step that involves physically handling the hardware. It should only be considered if other software-based diagnostic methods (like using Device Manager) do not reveal the cause of the problem. Additionally, this method assumes that the user has the technical skill and tools to safely perform such an operation, which might not be the case. Open a web browser and type the following: http://127.0.0.1: This method is not relevant to the issue. The address 127.0.0.1 is a loopback address used in network testing and does not provide information about local storage drives. Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used to display network configuration details and is not relevant to checking the status of storage drives. Therefore, starting with Device Manager to check if the mechanical hard drive is recognized by the operating system is the most appropriate first step. If the drive is not visible there, further investigation, possibly involving physical checks or swapping SATA ports, may be necessary.

175. A laptop has an NVMe drive (C:) and a mechanical hard drive (D:). When the user tries to save a spreadsheet to the D: drive, the user notices that the D: drive is not there. What should the technician do to see if the drive is recognized by the operating system?

     • Use the Disk Management Control Panel.
     • Determine if the hard drive service is set to start automatically.
     • Bring up a command prompt and type ipconfig.
     • Swap the data cables of the mechanical drive and the SSD.

     • Explanation & Hint: To check if the mechanical hard drive (D:) is recognized by the operating system on a laptop with an NVMe drive (C:) and a mechanical hard drive, the technician should: Use the Disk Management Control Panel: This is the most appropriate first step. Disk Management is a Windows utility that shows a detailed view of all the storage devices connected to the computer, including their format, partition style, and health status. By using Disk Management, the technician can see if the D: drive is visible to the operating system and whether it has any issues such as being unformatted or having a lost partition. The other options are less suitable for this situation: Determine if the hard drive service is set to start automatically: There isn’t a specific “hard drive service” that would need to be set to start automatically in Windows for a drive to be recognized. This option does not apply to the scenario described. Bring up a command prompt and type ipconfig: The ‘ipconfig’ command is used for displaying network configuration information and is not relevant for checking the status of storage drives. Swap the data cables of the mechanical drive and the SSD: In a laptop, swapping data cables isn’t usually feasible or relevant, as laptops typically have dedicated connectors for NVMe and SATA drives and do not use standard data cables like desktops. Additionally, physical manipulation of internal components should only be considered after confirming the drive’s status through software diagnostics. Therefore, the technician should start by opening the Disk Management tool to check if the D: drive is listed and to diagnose any visible issues. If the drive is not visible in Disk Management, further investigation may be necessary, potentially including hardware diagnostics.

176. A user reports that a drive is no longer there. The technician asks the user to demonstrate the problem. Within the application, the user demonstrates that the drive, that was present in the save options yesterday, is now no longer an option. What should the technician do to see if the drive is recognized by the operating system?

     • Use File Explorer.
     • Remove the drive and attach it to the SATA port used by the SSD. Reboot the computer and see if the drive is recognized.
