CompTIA A+ Core 2 (220-1102) — Question 480

A customer called the help desk to report that a new USB CD drive is not working. Which of the following tools should the technician use to diagnose the issue?

Answer options

• A. lusrmgr.msc
• B. devmgmt.msc
• C. certmgr.msc
• D. perfmon.msc

Correct answer: B

Explanation

The correct answer is B, devmgmt.msc, as this tool accesses Device Manager, allowing the technician to check the status of hardware devices, including USB CD drives. The other options are incorrect because lusrmgr.msc manages user accounts, certmgr.msc handles certificates, and perfmon.msc is used for performance monitoring, none of which are relevant to diagnosing hardware issues.
