CompTIA A+ Core 2 (220-1002) — Question 452

A technician is working on a Windows 10 PC that is running slowly.
Which of the following commands should the technician use to correct this issue? (Choose two.)

Answer options

• A. dir
• B. chkdsk
• C. dism
• D. ipconfig
• E. format
• F. diskpart

Correct answer: B, C

Explanation

The correct answers are B (chkdsk) and C (dism) because chkdsk checks for and repairs file system errors, which can slow down a PC, while dism is used to fix Windows image issues that can also lead to performance degradation. The other options, such as dir, ipconfig, format, and diskpart, do not address performance problems directly.
