ITE 8 Chapter 7 Exam Answers | ITE 7 Chapter 7 Exam Answers Full 100% 2023 2024

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

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

     Answers Explanation & Hints: 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. 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.
     

     Answers Explanation & Hints: Laptop CPUs are designed to use less power and generate less heat than desktop CPUs.

3. 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
     

     Answers Explanation & Hints: 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.

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

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

     Answers Explanation & Hints: 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.

5. 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.
     

     Answers Explanation & Hints: 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.

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

   • SODIMMs
   • SRAM
   • SIMMs
   • DIMMs

7. 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.
     

     Answers Explanation & Hints: Laptop CPUs are designed to generate less heat and therefore require smaller cooling mechanisms than their desktop counterparts.

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

   • SMTP
   • POP3
   • SNMP
   • HTTP
     

     Answers Explanation & Hints: 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.

9. What is a characteristic of laptop motherboards?

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

      Answers Explanation & Hints: The international mobile subscriber identity (IMSI) number is a unique mobile device number that is commonly programmed on the subscriber identity module (SIM) card or can be programmed on the phone by some service providers.

26. A technician is troubleshooting a laptop with an unresponsive touchscreen. What could be the probable cause?

    • The digitizer is faulty.
    • The DC jack is not grounded or is loose.
    • The battery is not seated properly.
