CompTIA A+ Core 1 (220-1101) — Question 355

A customer's Windows tablet PC was dropped and is no longer responding to touch input on the left half of the screen. The screen protector has several scratches, but the glass is not broken. Which of the following should a technician do to diagnose the issue?

Answer options

• A. Test the digitizer.
• B. Update the device drivers.
• C. Replace the damaged screen protector.
• D. Perform a factory reset.

Correct answer: A

Explanation

Testing the digitizer is essential because it determines if the touch input issue is due to a hardware failure. Updating device drivers or performing a factory reset might not resolve a hardware-related problem, and replacing the screen protector won't fix a damaged digitizer.
