CompTIA A+ Core 2 (220-1102) — Question 512

A user's enterprise-issued smartphone does not respond to touch after starting up the operating system. Which of the following should a technician try next?

Answer options

• A. Contact the vendor for assistance.
• B. Replace the screen assembly.
• C. Confirm the touch screen functionality.
• D. Restore to factory settings.

Correct answer: C

Explanation

The correct answer is C because confirming the touch screen functionality is a necessary troubleshooting step to determine if the issue is hardware-related or a software problem. Options A and B are premature actions without diagnosing the touch screen first, and D would be a last resort after ensuring the touch screen itself is functional.
