CompTIA A+ Core 1 (220-1101) — Question 126

A user reports a monitor, keyboard, mouse, and headset are no longer functioning. The user has restarted the laptop and tested an alternative headset and monitor, but the issue persists. The technician notices the user has a printer, USB-C hub, and AC adapter plugged into the laptop. Which of the following should the technician do to MOST likely resolve the issue?

Answer options

• A. Verify the AC adapter voltage.
• B. Repair the operating system.
• C. Replace the user's USB-C hub.
• D. Reinstall the drivers for affected devices.
• E. Make sure the printer is not drawing too much power.

Correct answer: C

Explanation

The correct answer is C because a faulty USB-C hub can cause multiple peripherals to fail simultaneously. Verifying the AC adapter voltage (A) and repairing the operating system (B) may not directly address the issue since the problem is likely linked to the USB-C hub. Reinstalling drivers (D) and checking the printer's power draw (E) are also less likely to resolve the issue if the hub itself is defective.
