CompTIA A+ Core 2 (220-1102) — Question 37

A technician suspects the boot disk of a user’s computer contains bad sectors. Which of the following should the technician verify in the command prompt to address the issue without making any changes?

Answer options

• A. Run sfc / scannow on the drive as the administrator
• B. Run cleanmgr on the drive as the administrator
• C. Run chkdsk on the drive as the administrator
• D. Run dfrgui on the drive as the administrator

Correct answer: C

Explanation

The correct command is chkdsk, which is specifically designed to check the file system and disk for errors, including bad sectors, without making any changes. The sfc command is used for checking and repairing system files, cleanmgr is for disk cleanup, and dfrgui is for disk defragmentation, none of which directly address the issue of bad sectors.
