    • 0607:1234:aa10:ba01
    • 2001:0DB8
    • ba01
      

      Answers Explanation & Hints: An IPv6 address is made up of 128 bits that are represented as eight blocks of four hexadecimal digits that are called hextets. Because each hexadecimal digit represents four bits, each hextet represents 16 bits. The /64 network prefix indicates that the first 64 bits, or first four hextets, represent the network portion of the address. Because there are 128 bits in an IPv6 address, this leaves the last 64 bits, or last four hextets, to represent the host identifier. The value for the last four hextets is 0607:1234:aa10:ba01.

39. How can a user prevent specific applications from accessing a Windows computer over a network?

    • Enable MAC address filtering.
    • Disable automatic IP address assignment.
    • Block specific TCP or UDP ports in Windows Firewall.
    • Change default usernames and passwords.
      

      Answers Explanation & Hints: Network applications have specific TCP or UDP ports that can be left open or blocked in Windows Firewall. Disabling automatic IP address assignment may result in the computer not being able to connect to the network at all. Enabling MAC address filtering is not possible in Windows and would only block specific network hosts, not applications. Changing default usernames and passwords will secure the computer from unauthorized users, not from applications.

46. A technician is explaining the differences between inkjet printers and laser printers to a customer. Which two comparisons should the technician make? (Choose two.)

    • Inkjet printers are less expensive as an initial purchase than laser printers.
    • A laser printer is significantly slower than an inkjet printer.
    • Both laser and inkjet printers produce poor quality images.
    • The laser printer output is dry after printing, but an inkjet printer may still have wet ink on the paper after printing.
    • Inkjet printers use plain paper to make economical prints, but laser printers require more expensive thermal paper.

    • Explanation & Hint: When explaining the differences between inkjet and laser printers to a customer, the technician should make the following two comparisons: Inkjet printers are less expensive as an initial purchase than laser printers. This is generally true; the upfront cost of inkjet printers is typically lower than that of laser printers. The laser printer output is dry after printing, but an inkjet printer may still have wet ink on the paper after printing. Laser printers use toner and a heat process to fuse the toner to the paper, which results in a dry print immediately after printing. Inkjet printers, on the other hand, use liquid ink which can sometimes require a short time to dry. The other statements are incorrect: A laser printer is not significantly slower than an inkjet printer. In fact, laser printers are usually faster, especially for text documents. Both laser and inkjet printers can produce high-quality images, with modern printers often providing excellent image quality suitable for a variety of professional and home uses. Inkjet printers do not exclusively use plain paper to make economical prints, nor do laser printers require thermal paper. Both types of printers can print on a variety of media, and laser printers typically use regular printer paper, not thermal paper.

When the CPU overheats, most systems are designed to reboot automatically to prevent damage. While other components like the hard drive, RAID (Redundant Array of Independent Disks), BIOS (Basic Input/Output System), and wireless NIC (Network Interface Controller) can potentially cause issues, they are less likely to be the cause of sudden reboots compared to the power supply and CPU. A failing hard drive or RAID issues would more commonly result in system freezes or error messages, BIOS issues would typically prevent the computer from booting up correctly in the first place, and a faulty wireless NIC is more likely to cause network-related problems rather than a system reboot.

87. 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
    • RAID
    • BIOS
    • wireless NIC

    • Explanation & Hint: When a computer reboots suddenly without user intervention, particularly after being used for an extended period, it often points to issues related to hardware stability or overheating. The two hardware components most likely to cause this problem are: Power Supply: A faulty or inadequate power supply can cause the computer to reboot unexpectedly. If the power supply is unable to deliver consistent power due to age, damage, or being underpowered for the system’s requirements, it can lead to sudden reboots. This is especially likely if the computer has been under continuous use, placing more demand on the power supply. CPU (Central Processing Unit): The CPU is another common culprit in cases of unexpected reboots, often due to overheating. Continuous use can cause the CPU temperature to rise, especially if the cooling system (like fans or heat sinks) is not working effectively or if thermal paste has degraded.

89. 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
    • ROM
    • wireless NIC
    • motherboard

    • Explanation & Hint: CPU and Power Supply are indeed two pieces of hardware that could cause a computer to reboot randomly. Let’s explore why these are correct and why the other options are less likely: CPU (Central Processing Unit): The CPU is the brain of the computer, handling all the instructions it receives from hardware and software. Overheating is a common reason a CPU might cause the computer to reboot. If the CPU gets too hot, it can trigger a safety mechanism that restarts the computer to prevent damage. Additionally, a CPU that is malfunctioning or under extreme stress from processes can also lead to system instability and random reboots. Power Supply: As previously mentioned, a faulty or inadequate power supply can lead to instability in the computer’s operation. Inconsistencies in power delivery or a failing power supply unit can cause the computer to reboot unexpectedly. This is one of the most common hardware issues that lead to random reboots. Now, let’s discuss why the other options are less likely: Surge Strip: While a faulty surge strip can cause power issues, it’s more likely to cut off power entirely rather than cause random reboots. Surge strips typically protect against power surges and do not directly interact with the computer’s internal processes. ROM (Read-Only Memory): ROM is a type of non-volatile memory used mainly for firmware (a software that is closely tied to specific hardware). Issues with ROM are less likely to cause random reboots and more likely to result in boot failures or errors in executing firmware-related tasks. Wireless NIC (Network Interface Controller): A wireless NIC, which handles network connections, is unlikely to cause random reboots. Issues with a wireless NIC would more commonly result in network connectivity problems, not system instability. Motherboard: While a faulty motherboard can cause a wide range of issues, including reboots, it’s less common compared to CPU and power supply problems. Motherboard issues can be more complex and varied, affecting various aspects of the computer’s operation. In summary, the CPU and Power Supply are more directly linked to the common causes of random reboots, such as overheating and power instability, respectively.

90. 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
    • RAID
    • ROM
    • wireless NIC
    • motherboard

    • Explanation & Hint: In this scenario, the two pieces of hardware that could most likely cause a computer to reboot randomly throughout the day are the CPU and Power Supply. Here’s why these are the correct choices, and why the other options are less likely: CPU (Central Processing Unit): The CPU is crucial for processing all computer operations. If the CPU overheats or fails due to other issues like manufacturing defects or age, it can lead to system instability, causing the computer to reboot unexpectedly. Overheating is particularly common and can be triggered by inadequate cooling, dust buildup, or thermal paste degradation. Power Supply: The power supply is responsible for providing stable power to the computer. If it’s faulty, provides insufficient power, or fluctuates in power output, it can lead to random reboots. Power supply issues are a common cause of such problems, especially in older or lower-quality units. Now, let’s explain why the other options are less likely: RAID (Redundant Array of Independent Disks): RAID is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units. While RAID issues can lead to data loss or corruption, they are unlikely to cause the computer to reboot randomly. ROM (Read-Only Memory): ROM contains firmware used during the booting process. Problems with ROM would typically prevent a computer from booting up rather than causing it to reboot randomly. Wireless NIC (Network Interface Controller): A wireless NIC facilitates wireless networking. Issues with a wireless NIC would more likely lead to network connectivity problems, not random reboots of the entire system. Motherboard: The motherboard, while a central component, is less likely to be the cause compared to the CPU and power supply. However, it’s worth noting that a faulty motherboard can also lead to random reboots due to its role in connecting and managing all computer components. In summary, the CPU and Power Supply are the most likely culprits in this scenario due to their direct involvement in the computer’s power management and processing tasks.

91. 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
    • ROM
    • wireless NIC
    • motherboard

    • Explanation & Hint: For a computer that reboots several times before eventually starting, two suspect components that could be causing this issue are the Power Supply and the Motherboard. Here’s an explanation for these choices and why the other options are less likely: Power Supply: If the power supply is failing or not providing consistent power, it can cause the computer to reboot multiple times before it stabilizes and starts properly. Issues like power fluctuations or inadequate power output can lead to such behavior. The power supply is a common culprit in cases where a computer struggles to start up correctly. Motherboard: The motherboard is the central hub for all computer components. If there are issues with the motherboard, such as faulty capacitors, bad solder joints, or problems with the BIOS firmware that resides on it, it can lead to instability during the boot process. This can manifest as repeated reboots before the system successfully starts. Now, let’s discuss why the other options are less likely: CPU (Central Processing Unit): While a faulty CPU can cause a system to be unstable, it’s less likely to cause multiple reboots before a successful start. CPU problems typically result in a failure to boot or system instability after booting. BIOS (Basic Input/Output System): BIOS issues can prevent a computer from starting, but they are less likely to cause multiple reboots before a successful start. BIOS problems usually result in a failure to boot or error messages during the boot process. ROM (Read-Only Memory): ROM in this context usually refers to the memory where the BIOS firmware is stored. Like BIOS issues, ROM problems would more likely lead to boot failure or error messages rather than multiple reboots. Wireless NIC (Network Interface Controller): A wireless NIC is involved in network connectivity and is unlikely to cause issues with the boot process. Problems with a wireless NIC typically manifest as connectivity issues once the system has booted. In this scenario, the Power Supply and Motherboard are the most likely candidates due to their integral roles in providing power and facilitating the boot process.

92. 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
    • ROM
    • BIOS
    • RAID
    • wireless NIC

    • Explanation & Hint: In the scenario where a computer reboots several times before eventually starting, the two suspect components to consider are the Power Supply and the BIOS. Here’s why these components are likely suspects, along with explanations for why the other options are less likely: Power Supply: A failing or inadequate power supply can cause instability during the boot process. If the power supply is not delivering consistent and sufficient power, it can lead to the computer rebooting multiple times before it stabilizes enough to start properly. This is a common issue and should be one of the first components to check in such scenarios. BIOS (Basic Input/Output System): BIOS issues can lead to a variety of startup problems. If the BIOS is corrupted, improperly configured, or facing compatibility issues with hardware, it can cause the system to reboot repeatedly during the boot process. This might be due to the BIOS attempting to reset to safe parameters or encountering errors that prevent normal startup. Now, let’s consider why the other options are less likely: CPU (Central Processing Unit): While a faulty CPU can cause system instability, it generally leads to a failure to boot or system crashes rather than repeated reboots during the startup process. ROM (Read-Only Memory): ROM typically refers to the non-volatile memory where the BIOS is stored. Issues with ROM itself are rare and would more likely prevent the computer from starting at all rather than causing multiple reboots. RAID (Redundant Array of Independent Disks): Problems with RAID configurations usually lead to data access or storage issues. While it’s possible for RAID issues to impact the boot process, especially if the system disk is part of a RAID array, it’s less likely to cause repeated reboots compared to power supply or BIOS issues. Wireless NIC (Network Interface Controller): A wireless NIC, being primarily responsible for network connectivity, is unlikely to cause issues with the boot process. Problems with a wireless NIC would typically manifest as network-related issues after the system has booted. In summary, the Power Supply and BIOS are the most likely components to investigate in this case, given their crucial roles in powering the system and initiating the boot process.

93. 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
    • RAID
    • wireless NIC

    • Explanation & Hint: In the scenario where a computer reboots unexpectedly while a user is working on a spreadsheet, the two components most likely to cause this issue are the CPU and Power Supply. Here’s an explanation for these choices and why the other options are less likely: CPU (Central Processing Unit): The CPU is critical for processing all the tasks on a computer. If the CPU is overheating, it could cause the computer to reboot unexpectedly as a protective measure. Additionally, other CPU issues like voltage irregularities or physical damage can also lead to sudden reboots. Power Supply: An unstable or failing power supply can cause the computer to reboot without warning. Issues like power surges, inadequate power output, or a failing power supply unit can lead to sudden loss of power or power fluctuations, resulting in the computer rebooting. Now, let’s discuss why the other options are less likely: ROM (Read-Only Memory): ROM, which typically contains firmware like the BIOS, is not usually a direct cause of random reboots. Issues with ROM would more likely lead to boot problems or errors in firmware execution, rather than unexpected reboots during regular operation. BIOS (Basic Input/Output System): While BIOS issues can cause startup problems, they are less likely to cause a computer to reboot randomly during regular operations like working on a spreadsheet. RAID (Redundant Array of Independent Disks): RAID is a data storage technology used for redundancy and performance. Problems with RAID arrays generally lead to data access or storage issues and are unlikely to cause sudden reboots unless the system’s primary disk is affected. Even then, it’s a less common cause compared to CPU or power supply issues. Wireless NIC (Network Interface Controller): A wireless NIC handles network connections and is unlikely to cause the system to reboot. Issues with a wireless NIC would more commonly result in network connectivity problems. In summary, the CPU and Power Supply are the most likely culprits behind a computer rebooting unexpectedly while in use, due to their direct roles in processing and power management.

94. 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
    • RAID
    • wireless NIC

    • Explanation & Hint: If a computer reboots suddenly while a user is working on a spreadsheet, this can be indicative of issues with specific hardware components. The two components most likely to cause such an issue are: Power Supply: A faulty or unstable power supply unit (PSU) is a common cause of unexpected reboots. If the PSU is unable to deliver consistent power, possibly due to age, wear, damage, or being underpowered for the computer’s requirements, it can result in the computer rebooting suddenly. This kind of issue can occur regardless of the specific tasks being performed on the computer. Motherboard: The motherboard, being the central hub that connects all components of the computer, could also be a cause of sudden reboots. Issues such as faulty capacitors, poor soldering, electrical short circuits, or other hardware failures on the motherboard can lead to instability and cause the system to reboot. While other components like the CPU, BIOS (Basic Input/Output System), RAID (Redundant Array of Independent Disks), and wireless NIC (Network Interface Controller) might also be responsible for various computer issues, they are less likely to cause sudden reboots in the scenario described: A CPU problem would more commonly lead to system freezes or shutdowns due to overheating, rather than reboots. BIOS issues typically prevent the computer from booting correctly or affect system stability in more consistent ways. Problems with RAID setups usually manifest in data access or storage issues. A malfunctioning wireless NIC would primarily affect network connectivity, not cause the system to reboot.

95. 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
    • BIOS
    • ROM

    • Explanation & Hint: When a computer reboots suddenly without user intervention, particularly after being used for an extended period, it often points to issues related to hardware stability or overheating. The two hardware components most likely to cause this problem are: Power Supply: A faulty or inadequate power supply can cause the computer to reboot unexpectedly. If the power supply is unable to deliver consistent power due to age, damage, or being underpowered for the system’s requirements, it can lead to sudden reboots. This is especially likely if the computer has been under continuous use, placing more demand on the power supply. CPU (Central Processing Unit): The CPU is another common culprit in cases of unexpected reboots, often due to overheating. Continuous use can cause the CPU temperature to rise, especially if the cooling system (like fans or heat sinks) is not working effectively or if thermal paste has degraded. When the CPU overheats, most systems are designed to reboot automatically to prevent damage. While other components like the hard drive, RAID (Redundant Array of Independent Disks), BIOS (Basic Input/Output System), and wireless NIC (Network Interface Controller) can potentially cause issues, they are less likely to be the cause of sudden reboots compared to the power supply and CPU. A failing hard drive or RAID issues would more commonly result in system freezes or error messages, BIOS issues would typically prevent the computer from booting up correctly in the first place, and a faulty wireless NIC is more likely to cause network-related problems rather than a system reboot.

96. A client packet is received by a server. The packet has a destination port number of 137. What service application is the client requesting?

    • NetBIOS (NetBT)
    • SMB/CIFS
    • HTTPS
    • SLP

    • Explanation & Hint: The destination port number in a packet helps identify the service or protocol intended for the communication. If a client packet is received by a server with a destination port number of 137, it indicates that the client is requesting the NetBIOS (NetBT) service. Here’s a brief explanation of the services associated with the given port numbers and protocols: NetBIOS (NetBT): Port 137 is associated with NetBIOS Name Service. NetBIOS provides services related to the session layer of the OSI model and is used for LAN-based network communication. NetBIOS over TCP/IP (NetBT) uses port 137 for name resolution services. SMB/CIFS: The Server Message Block (SMB) protocol, often referred to in the context of the Common Internet File System (CIFS), typically uses ports like 445 or 139 (in combination with NetBIOS). Port 137 is not directly associated with SMB/CIFS. HTTPS: HTTPS (Hypertext Transfer Protocol Secure) uses port 443. It is the secure version of HTTP, used primarily for secure communication over a computer network within a web browser. SLP (Service Location Protocol): SLP uses port 427 for service discovery in local networks. It’s not associated with port 137. Therefore, a packet with a destination port number of 137 is meant for a NetBIOS service, specifically the NetBIOS Name Service.

97. A client packet is received by a server. The packet has a destination port number of 22. What service application is the client requesting?

    • SSH
    • SMB/CIFS
    • HTTPS
    • SLP

    • Explanation & Hint: The client packet with a destination port number of 22 is requesting the SSH (Secure Shell) service. Port 22 is the standard TCP/IP port assigned for SSH communications. SSH is a cryptographic network protocol used for operating network services securely over an unsecured network. It is commonly used for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.

98. A client packet is received by a server. The packet has a destination port number of 143. What service application is the client requesting?

    • IMAP
    • SMB/CIFS
    • HTTPS
    • SLP

    • Explanation & Hint: The client packet with a destination port number of 143 is requesting the IMAP (Internet Message Access Protocol) service. Port 143 is the standard port used by IMAP, which is a protocol for accessing email on a remote server from a local client. IMAP allows clients to read emails as if they were stored locally on their device, but actually, the emails are maintained on the server. As for the other options: SMB/CIFS: The Server Message Block (SMB) protocol and the Common Internet File System (CIFS) are used for file sharing, printer sharing, and other network communication tasks. These protocols typically use port 445 or 139, not port 143. HTTPS: HTTPS (Hypertext Transfer Protocol Secure) is used for secure communication over a computer network within a web browser and typically uses port 443. It is not related to port 143. SLP (Service Location Protocol): SLP is used for computers and other devices to find services in a local area network without prior configuration. It typically uses port 427, not port 143. Therefore, a packet with a destination port number of 143 is specifically requesting IMAP services.

99. A client packet is received by a server. The packet has a destination port number of 23. What service application is the client requesting?

    • Telnet
    • SMB/CIFS
    • HTTPS
    • SLP

    • Explanation & Hint: The client packet with a destination port number of 23 is requesting the Telnet service. Telnet is a network protocol used for bidirectional interactive text-based communication over a virtual terminal. It operates on port 23, which is the standard assignment for Telnet services. Telnet is often used for remote administration of devices but is less secure compared to modern protocols like SSH (Secure Shell) because it transmits data, including login credentials, in plaintext. As for the other options: SMB/CIFS: The Server Message Block (SMB) protocol and the Common Internet File System (CIFS) are used for network file sharing and printer services. These protocols typically operate on ports 139 and 445, not port 23. HTTPS: HTTPS (Hypertext Transfer Protocol Secure) is used for secure web browsing, encrypting the data exchanged between a web browser and a server. It operates on port 443, not port 23. SLP (Service Location Protocol): SLP is used for locating services in Local Area Networks (LANs) without prior configuration. This protocol typically uses port 427, not port 23. Therefore, a packet with a destination port number of 23 specifically indicates a request for Telnet services.

100. A client packet is received by a server. The packet has a destination port number of 161. What service application is the client requesting?

     • SNMP
     • SMB/CIFS
     • HTTPS
     • SLP

     • Explanation & Hint: The client packet with a destination port number of 161 is requesting the SNMP (Simple Network Management Protocol) service. SNMP is a widely used protocol for network management and monitoring. Port 161 is the designated port for SNMP agents to listen for SNMP requests from managers. SNMP is primarily used to collect information from, and configure, network devices such as routers, switches, printers, and servers. Explanation of the incorrect options: SMB/CIFS: Server Message Block (SMB) and Common Internet File System (CIFS) are protocols used for network file sharing and printer services. They typically use ports 139 and 445, not port 161. HTTPS: Hypertext Transfer Protocol Secure (HTTPS) is used for secure communication over a computer network within a web browser. It encrypts the data exchanged between a web browser and a server and operates on port 443, not port 161. SLP (Service Location Protocol): SLP is used for locating services in local area networks without prior configuration. It typically uses port 427, not port 161. Thus, a packet with a destination port number of 161 is specifically indicative of a request for SNMP services.

101. A client packet is received by a server. The packet has a destination port number of 389. What service application is the client requesting?

     • LDAP
     • SMB/CIFS
     • HTTPS
     • SLP

     • Explanation & Hint: The client packet with a destination port number of 389 is requesting the LDAP (Lightweight Directory Access Protocol) service. LDAP is used for accessing and maintaining distributed directory information services over an Internet Protocol network. Port 389 is the standard port for LDAP communications, facilitating operations like directory searches and modifications. Explanation of the incorrect options: SMB/CIFS: Server Message Block (SMB) and Common Internet File System (CIFS) are protocols used for network file sharing and printer services. They operate on ports 139 and 445, not port 389. HTTPS: Hypertext Transfer Protocol Secure (HTTPS) is used for secure web communications and typically operates on port 443. It’s not associated with port 389. SLP (Service Location Protocol): SLP is used for locating services in local area networks without prior configuration, typically operating on port 427, not port 389. Therefore, a packet with a destination port number of 389 is specifically indicative of a request for LDAP services.

102. A client packet is received by a server. The packet has a destination port number of 25. What service application is the client requesting?

     • SMTP
     • SMB/CIFS
     • HTTPS
     • SLP

     • Explanation & Hint: The client packet with a destination port number of 25 is requesting the SMTP (Simple Mail Transfer Protocol) service. SMTP is used for sending emails over the Internet. Port 25 is the standard port designated for SMTP communications and is primarily used for email transmission between mail servers or from email clients to mail servers for sending emails. Explanation of the incorrect options: SMB/CIFS: Server Message Block (SMB) and Common Internet File System (CIFS) are protocols used for network file sharing and printer services. They typically use ports 139 and 445, not port 25. HTTPS: Hypertext Transfer Protocol Secure (HTTPS) is used for secure web communications, operating typically on port 443. It’s not associated with port 25. SLP (Service Location Protocol): SLP is used for locating services in local area networks without prior configuration, typically operating on port 427, not port 25. Thus, a packet with a destination port number of 25 specifically indicates a request for SMTP services.

103. A client packet is received by a server. The packet has a destination port number of 427. What service application is the client requesting?

     • SLP
     • SMB/CIFS
     • SMTP
     • DNS

     • Explanation & Hint: The client packet with a destination port number of 427 is requesting the SLP (Service Location Protocol) service. SLP is used for locating services in local area networks without prior configuration. It typically operates on port 427, facilitating network services to find and use other services within the same network. Explanation of the incorrect options: SMB/CIFS: Server Message Block (SMB) and Common Internet File System (CIFS) are protocols used for network file sharing and printer services. They typically use ports 139 and 445, not port 427. SMTP: Simple Mail Transfer Protocol (SMTP), used for sending emails, operates typically on port 25. It’s not associated with port 427. DNS: The Domain Name System (DNS), which translates domain names to IP addresses, typically uses port 53, not port 427. Therefore, a packet with a destination port number of 427 is specifically indicative of a request for SLP services.

104. A client packet is received by a server. The packet has a destination port number of 53. What service application is the client requesting?

     • DNS
     • SMTP
     • DHCP
     • TFTP

     • Explanation & Hint: The client packet with a destination port number of 53 is requesting the DNS (Domain Name System) service. DNS is used for translating human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other on the network. Port 53 is the standard port used for both DNS queries and responses. Explanation of the incorrect options: SMTP: Simple Mail Transfer Protocol (SMTP), used for sending emails, typically operates on port 25. It is not associated with port 53. DHCP: Dynamic Host Configuration Protocol (DHCP), which is used for dynamically distributing network configuration parameters, such as IP addresses, typically uses ports 67 and 68, not port 53. TFTP: Trivial File Transfer Protocol (TFTP), a simplified version of FTP used to transfer files, typically uses port 69. It’s not associated with port 53. Therefore, a packet with a destination port number of 53 specifically indicates a request for DNS services.

105. A client packet is received by a server. The packet has a destination port number of 427. What service application is the client requesting?

     • SLP
     • SMTP
     • DNS
     • DHCP

     • Explanation & Hint: The client packet with a destination port number of 427 is requesting the SLP (Service Location Protocol) service. SLP is used for locating services in local area networks without prior configuration. It typically operates on port 427, facilitating network services to find and use other services within the same network. Explanation of the incorrect options: SMB/CIFS: Server Message Block (SMB) and Common Internet File System (CIFS) are protocols used for network file sharing and printer services. They typically use ports 139 and 445, not port 427. SMTP: Simple Mail Transfer Protocol (SMTP), used for sending emails, operates typically on port 25. It’s not associated with port 427. DNS: The Domain Name System (DNS), which translates domain names to IP addresses, typically uses port 53, not port 427. Therefore, a packet with a destination port number of 427 is specifically indicative of a request for SLP services.

106. Which is the compressed format of the IPv6 address 2001:0db8:0000:0000:0000:a0b0:0008:0001?

     • 2001:db8::a0b0:8:1
     • 2001:db80:0:1::80:1
     • 2001:db8::ab8:1:0:1000
     • 2001:db80:::1::80:1

     • Explanation & Hint: The compressed format of the IPv6 address 2001:0db8:0000:0000:0000:a0b0:0008:0001 can be derived by following the rules for IPv6 address compression. These rules allow for the omission of leading zeros in each 16-bit block and the replacement of one or more consecutive blocks of zeros with a double colon (::). However, the double colon can only be used once in an address to ensure its uniqueness. Given these rules, the correct compressed format for this IPv6 address is: 2001:db8::a0b0:8:1 Explanation of the options: 2001:db8::a0b0:8:1: Correct. It omits leading zeros and replaces consecutive blocks of zeros with a double colon. 2001:db80:0:1::80:1: Incorrect. This changes the value of the original address (the second block is db80 instead of db8) and misplaces zeros. 2001:db8::ab8:1:0:1000: Incorrect. This changes the value of the original address and does not correctly represent the zero blocks. 2001:db80:::1::80:1: Incorrect and invalid. Multiple uses of the double colon (::) are not allowed in a single IPv6 address, and it also changes the value of the original address.

116. What ACPI power state describes when the CPU and RAM are off and the contents of RAM have been saved to a temporary file on the hard drive?

     • S4
     • S1
     • S2
     • S3

     • Explanation & Hint: The ACPI (Advanced Configuration and Power Interface) power state that describes the condition where the CPU and RAM are off, and the contents of RAM have been saved to a temporary file on the hard drive, is known as S4. In the S4 state, also known as “hibernation,” the system saves the contents of the memory to a hard drive or other non-volatile storage. This allows the computer to turn off completely, which means the CPU, RAM, and most of the other components are powered down. When the system is powered back on, it can resume from where it left off by reading the saved data from the hard drive.

126. 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 laser printer is emitting too much radiation.
     • The wrong printer type has been selected.

     • 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.

127. 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.
     • The printer has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: When a printer starts printing unknown characters, it’s typically related to issues with communication or data interpretation between the computer and the printer. Two possible causes for this issue could be: The wrong or an outdated printer driver is installed: If the printer driver is incorrect or outdated, it may not translate the document data correctly for the printer, leading to the printing of unknown or garbled characters. Ensuring that the correct, up-to-date driver for the specific printer model is installed is crucial. The printer has been installed on the wrong port: If the printer is configured to use a port that it’s not actually connected to, or if the port settings are incorrect, this can result in communication problems, leading to printing errors like unknown characters. The other options listed are less likely to be direct causes of this specific issue. A loose connection might stop the printer from working altogether but is less likely to cause it to print unknown characters. The notion of a laser printer emitting too much radiation is not relevant to the issue of printing unknown characters. Lastly, a flimsy paper tray would typically cause paper jams or misfeeds, not issues with the characters being printed.

128. 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 printer has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: When a printer is printing incorrect colors, it’s typically an issue related to the ink or toner and the printer’s ability to accurately apply them. Two possible causes for this issue could be: The print heads might need to be cleaned and calibrated: Over time, print heads can become clogged or misaligned, especially in inkjet printers. This can result in colors not being printed correctly. Cleaning and calibrating the print heads can often resolve these color accuracy issues. An incorrect cartridge could be installed: If a cartridge is not the right type for the printer, or if it’s a color cartridge that’s been installed in the wrong slot, this can lead to incorrect colors being printed. Checking that all cartridges are correct for the model and are installed in the proper slots is important. The other options listed are less likely to be related to the issue of incorrect colors. The type of cable used or the specific port to which the printer is connected generally does not affect color output. Likewise, the quality or condition of the paper tray is not typically related to color printing issues.

129. 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 has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: The Toner Cartridge is Low: A low toner cartridge is a common cause of faded prints in printers. When the toner level is low, the printer is unable to apply a sufficient amount of toner to the paper, leading to lighter or uneven printing. Replacing or refilling the toner cartridge is the standard solution to this problem. The Paper Might be Incompatible with the Printer: Using paper that is not compatible with the printer can also result in faded prints. Different printers are designed to work with specific types of paper, and using the wrong kind can affect print quality. For example, inkjet printers require different paper types compared to laser printers to achieve optimal print quality. Ensuring that the paper used is suitable for the specific printer model can help in resolving print quality issues. The other provided options are less likely to cause faded prints: The Wrong Printer Type has been Selected: While this can affect overall print quality, it typically doesn’t result in faded prints. The Printer has been Installed on the Wrong Port: This would affect the printer’s ability to communicate with the computer, not the quality of the prints. The Paper Tray is Flimsy: A flimsy paper tray might lead to paper feed issues, but it’s not a direct cause of faded printing. In summary, checking the toner levels and verifying the compatibility of the paper with the printer are key steps in addressing the issue of faded prints.

130. 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 printer has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: The issue of the printer control panel displaying no image can be attributed to a couple of possible causes. Based on the options provided, the two most likely causes are: The Contrast of the Screen May be Set Too Low: If the contrast on the printer’s control panel is set too low, it might make the display appear blank or very faint. Adjusting the contrast settings could resolve this issue and bring back the display image. The Printer is Not Turned On: This might seem basic, but it’s a common oversight. If the printer is not properly turned on, the control panel will not display any image. Checking the power connection and ensuring that the printer is switched on is a fundamental step in troubleshooting this issue. The other options are less likely to be the cause of a blank control panel screen: The Room Temperature is Above Normal: While extreme temperatures can affect electronic devices, a slightly elevated room temperature is unlikely to cause the printer’s control panel to display no image. This issue would more likely arise under more extreme conditions. The Printer has been Installed on the Wrong Port: The port through which the printer is connected to a computer impacts data transmission for printing tasks, not the display of the printer’s control panel. The Paper Tray is Flimsy: The condition of the paper tray is unrelated to the display functionality of the printer’s control panel. A flimsy paper tray might cause paper feed issues, but it would not affect the control panel display. In summary, checking the contrast settings of the screen and ensuring that the printer is actually turned on are practical first steps to address the issue of the printer control panel displaying no image.

131. 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 printer has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: The issue of paper being creased after printing can be attributed to a couple of possible causes. Based on the options provided, the two most likely causes are: 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 firmly adjusted, it can lead to misfeeds or skewed feeding of the paper through the printer. This misalignment can cause the paper to crease as it passes through the printer’s internal mechanisms. The Paper Might be Loaded Incorrectly: Incorrectly loaded paper can easily lead to creases. This can happen if the paper is not placed squarely in the tray, is overloaded, or if different sizes or types of paper are mixed in the tray. Ensuring that the paper is loaded correctly and in alignment with the printer’s specifications is crucial to avoid such issues. The other options are less likely to cause paper creasing: Print Jobs are Being Sent to the Wrong Printer: Sending a print job to the wrong printer would not result in paper creasing. It would either result in no printout or a printout from a different printer. The Printer has been Installed on the Wrong Port: The port through which the printer is connected to a computer affects data transmission and has no impact on the physical process of printing, such as paper handling. The Paper Tray is Flimsy: While a flimsy paper tray might contribute to paper feed issues, it is less likely to be a direct cause of paper creasing compared to improper adjustment of the paper-feed tray or incorrect paper loading. In summary, ensuring that the paper-feed tray is properly adjusted and that the paper is loaded correctly are important steps in resolving the issue of paper creasing after printing.

132. A receptionist is complaining about the following printer issue: My impact printer produces faded or light characters. What are two possible causes of this issue? (Choose two.)

     • The ribbon may be worn out.
     • The ribbon may be damaged.
     • The print queue is overloaded.
     • The printer has been installed on the wrong port.
     • The paper tray is flimsy.

     • Explanation & Hint: For the issue of an impact printer producing faded or light characters, the two most likely causes are: The Ribbon May be Worn Out: In impact printers, the ribbon is an essential component for transferring ink onto the paper. Over time and with extensive use, the ribbon can become worn out, leading to faded or light characters being printed. Replacing the worn-out ribbon with a new one should resolve this issue. The Ribbon May be Damaged: Besides general wear and tear, the ribbon can also be damaged or have defects. Damage to the ribbon, such as tears, creases, or inconsistent ink distribution, can result in poor print quality, including faded or light characters. Inspecting the ribbon for damage and replacing it if necessary is a recommended step. The other options are less likely to be the cause of this specific issue: The Print Queue is Overloaded: While an overloaded print queue can lead to delays in printing or errors in print jobs, it does not directly affect the quality of the print itself, such as causing faded or light characters. The Printer has been Installed on the Wrong Port: The port through which the printer is connected to a computer affects its ability to receive data for printing jobs. This would not typically impact the physical quality of the print, such as the intensity of the characters. The Paper Tray is Flimsy: The condition of the paper tray is unlikely to affect the quality of printing in terms of ink intensity. Issues with a flimsy paper tray are more likely to lead to paper jams or misalignment, not faded printing. In summary, checking and potentially replacing the printer’s ribbon, whether due to wear or damage, are key steps in addressing the issue of faded or light characters in impact printer output.

133. 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.
     • The printer has been installed on the wrong port.
     • The printer service is stopped or not working properly.

     • Explanation & Hint: For the issue of paper not being fed into the printer, the two most likely causes are: The Paper May be Wrinkled: If the paper loaded into the printer is wrinkled, it can prevent proper feeding into the printer. Wrinkled paper can jam or misalign within the printer’s feeding mechanism, leading to the paper not being fed at all. Ensuring that the paper is smooth and free of wrinkles before loading it into the printer can help resolve this issue. The Printer Could be Set to Print to a Different Paper Size than is Currently Loaded: If the printer’s settings are configured for a different paper size than the size of the paper actually loaded in the tray, this can cause feeding issues. The printer might attempt to feed paper from a different tray or fail to pick up the paper altogether. Adjusting the printer settings to match the actual paper size loaded in the tray is essential for proper functioning. The other options are less likely to be the cause of this specific issue: The Paper Tray is Flimsy: While a flimsy or damaged paper tray could potentially cause issues with paper alignment or stability, it is less directly related to the problem of paper not being fed into the printer compared to issues with the paper itself or printer settings. The Printer has been Installed on the Wrong Port: The port through which the printer is connected to a computer affects its ability to receive print jobs, not the mechanical process of feeding paper. The Printer Service is Stopped or Not Working Properly: Issues with the printer service would typically affect the printer’s ability to process print jobs or communicate with the computer, rather than the mechanical feeding of paper. In summary, ensuring that the paper is not wrinkled and that the printer settings match the loaded paper size are important steps in resolving the issue of paper not being fed into the printer.

134. 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 printer lid has not been closed securely.
     • The room temperature is above normal.
     • The printer does not have enough RAM.

     • Explanation & Hint: Understood, the two possible causes for the issue of a printer printing unknown characters, based on the provided options, are: The Wrong or an Outdated Printer Driver is Installed: This is a common cause of printing issues. Printer drivers are crucial for the proper communication between the computer and the printer. If the driver is incorrect or outdated, it may not translate the print commands correctly, leading to the printer outputting unknown or garbled characters. Updating or reinstalling the correct printer driver often resolves this problem. The Printer has a Loose Connection: A loose connection between the printer and the computer can result in incomplete or erratic data transmission. This can lead to the printer receiving incomplete or corrupt data, resulting in the printing of unknown characters. Checking and securing all cables and connections between the printer and the computer (or network, if applicable) is important for ensuring reliable communication and proper printing. The other provided options are less likely to cause this specific issue: The Printer Lid has Not Been Closed Securely: While important for the operation of some printers, an unsecured lid typically leads to mechanical issues (like paper jams) rather than the printing of unknown characters. The Room Temperature is Above Normal: While extreme temperatures can affect hardware performance, a slightly elevated room temperature is unlikely to cause a printer to output unknown characters. The Printer Does Not Have Enough RAM: Insufficient RAM in a printer might lead to issues with processing large or complex documents, but it’s more likely to slow down printing or cause incomplete prints rather than the printing of unknown characters. Ensuring that the printer driver is up to date and correct for the printer model, along with checking for secure and proper connections, are the key steps in resolving the issue of unknown characters being printed.

135. 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 service is stopped or not working properly.
     • The printer does not have enough RAM.
     • The print queue is overloaded.

     • Explanation & Hint: The issue of a printer printing incorrect colors can be attributed to a couple of possible causes. Based on the options provided, the two most likely causes are: The Print Heads Might Need to be Cleaned and Calibrated: Over time, print heads can become clogged with ink or dust, which can affect their ability to accurately dispense ink. This can lead to incorrect colors being printed. Additionally, if the print heads are misaligned (a calibration issue), it can also result in color inaccuracies. Cleaning and calibrating the print heads are common solutions to this problem. An Incorrect Cartridge Could be Installed: If an incorrect ink or toner cartridge is installed in the printer, it could lead to wrong color output. This can happen if the cartridge is not compatible with the printer model or if it is a color cartridge placed in the wrong slot. Ensuring that the correct cartridges are installed and properly seated can resolve this issue. The other options are less likely to be the cause of incorrect color printing: The Printer Service is Stopped or Not Working Properly: While a stopped or malfunctioning printer service could lead to printing issues, it is more likely to result in no print output or error messages rather than incorrect colors. The Printer Does Not Have Enough RAM: Insufficient printer RAM can affect the processing of large or complex print jobs but is less likely to be the direct cause of incorrect color output. It might slow down the printing or cause incomplete prints. The Print Queue is Overloaded: An overloaded print queue can lead to delays in printing or mixed-up print jobs but does not typically cause a change in the color output of the prints. In summary, checking and maintaining the print heads and ensuring the correct ink or toner cartridges are installed are crucial steps in resolving the issue of a printer producing prints with incorrect colors.

136. 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.
     • Use the Msconfig utility.
     • Boot into UEFI/BIOS and see if the drive appears.
     • Remove the drive and attach it to the SATA port used by the SSD. Reboot the computer and see if the drive is recognized.

     • Explanation & Hint: To determine if the D: drive (the mechanical hard drive) is recognized by the operating system, the technician should follow these steps: Use the Disk Management Control Panel: This is the first and most straightforward step. The Disk Management tool in Windows provides a clear view of all the storage devices connected to the system and their status. Here’s how to access it: Right-click on the Start button and select “Disk Management,” or press Windows Key + X and select “Disk Management.” In the Disk Management window, look for the mechanical hard drive. It should be listed with its capacity and partitions. If the drive is shown but does not have a drive letter, it can be assigned one right from this tool. Boot into UEFI/BIOS and See if the Drive Appears: If the drive does not appear in Disk Management, the next step is to check if it is recognized at a hardware level. This involves restarting the computer and entering the UEFI/BIOS setup: Restart the computer and enter the UEFI/BIOS setup (this usually involves pressing a key like F2, Del, or Esc during boot-up, but the exact key can vary depending on the manufacturer). Once in the UEFI/BIOS, navigate to the section where it lists the storage devices. If the mechanical hard drive is not listed here, it indicates a potential hardware issue or connection problem. The other options, while possible, are less immediate or practical as initial steps: Use the Msconfig Utility: The System Configuration utility (msconfig) is more related to startup processes and services and is not typically used for managing or viewing storage devices. Remove the Drive and Attach it to the SATA Port Used by the SSD: This is a more advanced step and should be performed only if the above methods fail to recognize the drive. It involves physically swapping the drives’ connections, which can be helpful in diagnosing a faulty port or cable. However, this should be done cautiously and is typically a last resort after software-level checks have been exhausted.

     • The screen resolution needs recalibration.
     • The screen refresh rate is too low.

     • Explanation & Hint: If a technician is working on a laptop and finds that the GPS is not functioning, the most probable cause from the given options is that Airplane mode is turned on. When Airplane mode is enabled, it disables all wireless communication functions of the device, including Wi-Fi, Bluetooth, and often GPS, to comply with airline regulations. If Airplane mode is accidentally left on, it would prevent the GPS from functioning properly. The other options are less likely to affect the GPS functionality: The GPU (Graphics Processing Unit) overheating: An overheating GPU can cause issues primarily related to graphics processing, display output, and system stability. It is not directly related to the functioning of GPS. The screen resolution needs recalibration: Screen resolution and calibration are related to the visual display and touch input accuracy (if it’s a touchscreen) but do not impact GPS functionality. The screen refresh rate is too low: The refresh rate of the screen affects how smoothly content is displayed and is unrelated to GPS functionality. Therefore, the technician should first check if Airplane mode is active and turn it off if necessary to see if that resolves the GPS issue.

148. A technician is working on a laptop and the GPS is not functioning. What is a probable cause for this situation?

     • Airplane mode is turned on.
     • Wi-Fi is turned off.
     • The screen resolution needs recalibration.
     • The screen refresh rate is too low.

     • Explanation & Hint: If a technician is working on a laptop and the GPS is not functioning, the most probable cause from the given options is that Airplane mode is turned on. When Airplane mode is enabled, it generally disables all wireless communications, which can include not only Wi-Fi and Bluetooth but also GPS in some laptops, particularly if the GPS functionality is integrated with other wireless communication hardware. The other options are less likely to affect GPS functionality: Wi-Fi is turned off: While turning off Wi-Fi disables wireless internet connectivity, it typically does not affect the GPS functionality directly. However, it’s worth noting that some devices use Wi-Fi networks to assist in location determination (known as Wi-Fi triangulation), but this is different from true GPS functionality. The screen resolution needs recalibration: The screen resolution and calibration are related to visual display and touch input accuracy (if it’s a touchscreen) but do not impact the functionality of the GPS system. The screen refresh rate is too low: The refresh rate of the screen affects the smoothness of visual content display and is not related to the functioning of the GPS system. So, the first step the technician should take is to check if Airplane mode is activated and turn it off if it is. This could potentially restore GPS functionality if the laptop’s GPS is indeed affected by this mode.

The other options are less likely to resolve the issue of color discrepancies: Configure the printer for duplex printing: Duplex printing refers to printing on both sides of the paper. This setting does not affect the color accuracy or quality of the prints and is unrelated to the issue at hand. Power cycle the printer: While power cycling (turning the printer off and then on again) can resolve many electronic and software glitches, it is unlikely to fix issues related to color accuracy unless the issue is a temporary glitch in the printer’s color processing. Update the OS: Updating the operating system of the computer can resolve various issues and is generally good practice, but it’s unlikely to directly affect the color accuracy of prints from a printer, unless the issue is specifically related to printer drivers or color profiles managed by the OS. Replace the pickup roller: The pickup roller is responsible for feeding paper into the printer. Issues with the pickup roller can lead to paper jams or feed problems but would not cause color discrepancies between the screen and printed documents. Therefore, the recommended first step is to calibrate the printer to improve the color match between the printed documents and the screen display. This process might involve using specific calibration tools or software provided by the printer manufacturer.
