CompTIA A+ Core 2 (220-1102) — Question 64

A user reports a PC is running slowly. The technician suspects high disk I/O. Which of the following should the technician perform NEXT?

Answer options

• A. resmon.exe
• B. msconfig.exe
• C. dfrgui.exe
• D. msinfo32.exe

Correct answer: A

Explanation

The correct answer is A, as resmon.exe (Resource Monitor) provides detailed information about disk usage, helping the technician diagnose high disk I/O. Options B (msconfig.exe), C (dfrgui.exe), and D (msinfo32.exe) do not focus specifically on real-time resource monitoring and are less relevant for identifying disk I/O issues.
