CompTIA A+ Core 2 (220-1002) — Question 81

A technician is troubleshooting a computer that may have some corrupt operating system files. Which of the following command line tools should the technician use to check these files?

Answer options

Correct answer: D

Explanation

The correct answer is D, sfc, which stands for System File Checker, and is specifically designed to scan and repair corrupted system files. Option A, dism, is used for servicing Windows images and can fix issues but is not primarily for checking system files. Option B, chkdsk, checks for disk errors but does not focus on operating system file corruption. Option C, diskpart, is a disk partitioning tool and is not related to file verification.
