Question 1

A client's monitor is not displaying an image when connected to their PC, but the PC seems to be running with no apparent issues. What is the most likely solution?

Correct Answer: Check if the monitor cable is securely connected to both the PC and the monitor.

The most likely solution is to check if the monitor cable is securely connected to both the PC and the monitor. If the PC seems to be running with no apparent issues but the monitor is not displaying an image, the problem is likely related to the connection between the PC and the monitor. A loose or damaged cable can prevent the video signal from reaching the monitor. The other options, such as replacing the monitor, removing and reinstalling the RAM, or replacing the power supply, are less likely to be the cause of the issue if the PC is running normally. It's best to start with the simplest potential solution, which is checking the cable connection.

Question 2

A client reports that their external hard drive is not recognized by their laptop when connected through the USB port. The hard drive has been confirmed to work on another computer. What troubleshooting step should you recommend first?

Correct Answer: Try connecting the external hard drive to a different USB port on the laptop.

The best first troubleshooting step is to try connecting the external hard drive to a different USB port on the laptop. This helps determine if the issue is with the specific USB port or the laptop's USB configuration in general. Reformatting the drive may lead to data loss and should only be considered after other troubleshooting steps have been exhausted. Reinstalling the operating system or replacing the motherboard are far too drastic as initial steps and are unlikely to resolve the specific issue of an unrecognized external drive.

Question 3

Sally recently bought a new scanner but she is unable to use it. She has not installed the necessary drivers to allow it to function with her computer. What should Sally do to resolve this issue?

Correct Answer: Visit the manufacturer's website and download the appropriate driver for her scanner model

The best answer is to visit the manufacturer's website and download the appropriate driver for her scanner model. Drivers are software that allow hardware devices like scanners to communicate with the computer's operating system. Without the correct driver installed, the scanner will not function properly. The driver can usually be found on the manufacturer's website, and it is important to download the driver specific to the scanner model and the operating system being used. Restarting the scanner, using Windows Update, or swapping the cable will not resolve the issue if the necessary driver is not installed.
