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?

Options

Adism
Bchkdsk
Cdiskpart
Dsfc

Explanation

The marked answer is chkdsk (Check Disk), which scans the filesystem for errors and bad sectors that can cause files - including OS files - to become corrupt or inaccessible, and can attempt repairs. It is worth noting that sfc (System File Checker - option D) is the tool most specifically designed to scan and restore corrupt Windows system files by comparing them against a cached copy, and is frequently cited in this context. chkdsk operates at the disk/filesystem layer and is the correct answer here when the root cause is suspected to be disk-level corruption. diskpart is a disk partitioning utility and does not check file integrity. dism (Deployment Image Servicing and Management) repairs the Windows component store and is typically used when sfc cannot fix corrupted files on its own.
