Question 1

A user's webcam is not working during video calls. What should you do first to troubleshoot?

Restart the computer. Unplug and reconnect the USB cable. Replace the webcam. Check if the webcam is enabled and selected as the video source in the video call application.

Correct Answer: Check if the webcam is enabled and selected as the video source in the video call application.

The first step in troubleshooting a non-functional webcam during video calls is to verify that the webcam is enabled and selected as the video source within the video call application's settings. This ensures that the application is attempting to use the correct webcam and that the webcam is not disabled or blocked by the application. If the webcam is not enabled or selected, the video call will not be able to access the webcam feed. The other options, such as restarting the computer, replacing the webcam, or unplugging and reconnecting the USB cable, should be attempted only after confirming that the webcam is properly configured within the application.

Question 2

A customer reports that their printer is not printing any documents. What should you check first?

Uninstall and reinstall the printer driver. Replace the printer's USB cable. Replace the printer's ink cartridges. Ensure the printer is turned on and connected to the computer.

Correct Answer: Ensure the printer is turned on and connected to the computer.

When troubleshooting a printer that is not printing documents, the first step should be to verify that the printer is powered on and properly connected to the computer. This basic check ensures that there is a proper communication channel between the printer and the computer. If the printer is not turned on or not connected correctly, it will not be able to receive print jobs from the computer. Replacing ink cartridges, uninstalling and reinstalling the printer driver, or replacing the USB cable should only be considered after confirming that the printer is powered on and connected properly.

Question 3

A user's external hard drive is not recognized by their computer. What should be done to diagnose the issue?

Try connecting the hard drive to another USB port or a different computer. Format the hard drive. Replace the computer's motherboard. Install a new hard drive.

Correct Answer: Try connecting the hard drive to another USB port or a different computer.

Connecting the hard drive to a different USB port or computer will help determine if the issue is with the hard drive, cable, or computer. Other options may lead to data loss or unnecessary disassembly.
