IT Essentials v7.0:

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.

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 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.
