CompTIA A+ Core 2 (220-1002) — Question 332

A user's PC has been running slowly. The user says there have been no changes to the PC. Which of the following tools should the technician use to troubleshoot the cause of the speed reduction?

Answer options

• A. DxDiag
• B. Windows Memory Diagnostic
• C. Performance tab in Task Manager
• D. Disk defragmenter

Correct answer: C

Explanation

The Performance tab in Task Manager provides real-time data on resource usage and can help identify any processes that are consuming excessive CPU or memory. DxDiag is primarily used for diagnosing DirectX-related issues, while the Windows Memory Diagnostic focuses on RAM problems, and the Disk defragmenter helps with disk optimization, none of which directly address overall performance issues.
