IT Essentials (Version 7.00) – IT Essentials 7.0 Chapter 7 Exam Answers

  1. To clean laptops, which two products are recommended? (Choose two.)

    • cotton swabs
    • mild cleaning solution
    • ammonia
    • rubbing alcohol
    • car wax
      Explanation:

      To clean a laptop computer, mild substances and lint-free cloths are required. Cleaners should be nonabrasive. Otherwise they can damage the laptop components.

  2. What are three common input devices found on laptops? (Choose three.)

    • touchpad
    • fingerprint reader
    • web camera
    • external monitor
    • PS/2 keyboard
    • AC power connector
      Explanation:

      Touchpads, fingerprint readers, and web cameras are common devices on modern laptops. An external monitor is an output device. While a PS/2 keyboard is an input device, it is not commonly used with laptops. An AC power connector provides a method to recharge the battery, but provides no data input to the laptop.?

  3. Which two statements are true of a laptop CPU when compared to a desktop CPU? (Choose two.)

    • Laptop CPUs operate at higher clock speeds.
    • Laptop CPUs use smaller cooling devices.
    • Laptop CPUs consume more power.
    • Laptop CPUs are interchangeable with desktop CPUs.
    • Laptop CPUs are designed to produce less heat.
      Explanation:

      Laptop CPUs are designed to use less power and generate less heat than desktop CPUs.

  4. A technician has been asked to decide which laptop components should be cleaned on a monthly basis as part of a maintenance routine. What are two examples of components that should be included? (Choose two.)

    • exterior case
    • keyboard
    • CPU
    • optical drive
    • RAM
      Explanation:

      Routine preventive maintenance includes the cleaning of parts that can get dirty with everyday use. Internal components are not required to be cleaned as often as external parts. Nonabrasive cleaners should be used to ensure that no damage is caused to laptop components.

  5. What are two methods typically used on a mobile device to provide internet connectivity? (Choose two.)

    • cellular
    • Zigbee
    • Wi-Fi
    • Z-Wave
    • GPS
      Explanation:

      Mobile devices commonly use Wi-Fi and cellular to connect to the internet. The cellular connection uses the cellular data network for a fee. The Wi-Fi connection uses an 802.11 wireless network in the area to connect to the internet.

  6. A customer brings a laptop into a computer repair shop. The technician can tell that the laptop is powered on by the power light, but nothing displays on the screen. What are two possible issues that could cause this symptom? (Choose two.)

    • The backlight needs adjusting.
    • The display properties need adjusting.
    • The laptop has gone into sleep mode.
    • The screen cutoff switch needs cleaning or is damaged.
    • The video cable is loose.
      Explanation:

      A dark screen on a laptop when the display is up and the laptop is powered on could happen because the laptop is in sleep mode. Tap a key to see if that is the case. If that does not work, remove the battery and AC power cord, then reinstall the battery and attach the power cord and try powering on again. The problem could also be a dirty or damaged screen cutoff switch. Use the repair manual to locate and clean or replace the switch.

  7. Which type of RAM modules are designed for the space limitations of laptops?

    • SODIMMs
    • SRAM
    • SIMMs
    • DIMMs
      Explanation:

      SRAM is not used for desktops or laptops as a RAM module, but as L1 cache inside the CPU. SIMMs were replaced by DIMMs on desktops as RAM modules.

  8. What is a design consideration for mobile CPUs used in laptops compared with desktop CPUs?

    • They are interchangeable with desktop CPUs.
    • They require smaller cooling mechanisms than desktops do.
    • They operate at higher clock speeds than desktops do.
    • They consume more power than desktops do.
      Explanation:

      Laptop CPUs are designed to generate less heat and therefore require smaller cooling mechanisms than their desktop counterparts.

  9. Which protocol can be used to transfer messages from an email server to an email client?

    • SMTP
    • POP3
    • SNMP
    • HTTP
      Explanation:

      SMTP is used to send mail from the client to the server but POP3 is used to download mail from the server to the client. HTTP and SNMP are protocols that are unrelated to email.

  10. What is a characteristic of laptop motherboards?

    • Laptop motherboards use the same form factors as desktop motherboards.
    • Laptop motherboards are proprietary.
    • Laptop motherboards use standard form factors.

      Explanation:

      Digitizers are used in mobile device touchscreens. The digitizer converts user touch actions such as a swipe or tap into an input digital signal.

  14. What type of backlight is used in an LED display?

    • LCD
    • LED
    • CCFL
    • light-generating pixels
      Explanation:

      Light-emitting diode (LED) displays use an LED backlight to illuminate pixels on the screen. In contrast, liquid crystal displays (LCDs) use either an LED or cold cathode fluorescent lamp (CCFL) backlight. Organic LEDs (OLEDs) do not use a backlight.

  15. Where is an integrated microphone normally located on a laptop?

    • near the exterior on either side of the keyboard by the plastic frame
    • by the exterior ports
    • in the top of the display
    • under the keyboard near the pointing device or touchpad
      Explanation:

      A laptop webcam, microphone, and wireless antenna are commonly located in the top of the display.

  16. Which ACPI state turns the CPU and RAM off and copies the contents of RAM to a temporary file on the hard disk?

    • S0
    • S1
    • S2
    • S3
    • S4
      Explanation:

      The Advanced Configuration and Power Interface (ACPI) standard provides support for power states that are very important to mobile devices such as laptops.

      S0 – The computer is on and CPU running.
      S1 – CPU and RAM have power, but unused devices are powered down.
      S2 – CPU is off; RAM is refreshed.
      S3 – CPU is off; RAM is set to a slow refresh rate.
      S4 – CPU and RAM are off (and RAM contents saved to a temp file).
      S5 – The computer is off.

  17. What could be used in conjunction with a laptop in order to read flash media?

    • SSD
    • card reader
    • M.2 card
    • SO-DIMM
      Explanation:

      A flash card reader (sometimes simply called a card reader) accepts a variety of flash card types and commonly attaches to a USB port.

  18. Which step would be important in the removal of laptop memory?

    • Align the memory module notch at a 45-degree angle and press to release.
    • Attach an AC adapter before starting the procedure.
    • Press outward on the clips that hold the memory module.
    • Gently press down on the memory module until it releases from the slot.

  19. Which laptop component would be considered an FRU?

    • SODIMM
    • display
    • battery
    • external card reader
      Explanation:

  20. Which characteristic should be considered when a replacement mobile device battery is being selected?

    • It has the same power ratings.
    • It is from the same manufacturer.
    • It provides a warranty.

  25. A technician has been called on site to help a user who has a laptop problem. At which point should the technician look online for additional possible solutions to a laptop problem?

    • after questioning the user
    • before establishing a theory of probable cause
    • after testing a theory to determine the cause
    • after implementing preventive measures
      Explanation:

      The steps of the troubleshooting process are as follows:

      Identify the problem.
      Establish a theory of probable cause.
      Test the theory to determine the cause.
      Establish a plan of action to resolve the problem and implement the solution.
      Verify full system functionality and, if applicable, implement preventive measures.
      Document findings, actions, and outcomes.
      It is during step 4 that if no solution is achieved in the previous step that a technicians needs further research.
