Disk, File, Informational, and OS Management Commands for A+
Short answer
These commands are used by technicians to inspect and perform basic repairs on filesystems, gather identity and version information, manage local accounts, and refresh or report Group Policy. Examples include running chkdsk to fix filesystem errors, using robocopy for large data migrations, and running sfc to repair protected system files.
Why it appears on the exam
- Which command would you use to repair protected system files? (sfc /scannow) - Which command displays the Windows build number? (winver) - Which tool copies files and preserves attributes with mirroring options? (robocopy)
Key concepts
Concept 1
Required terms
chkdsk: Checks a disk for file system errors and optionally attempts repairs; common switches include /f (fix) and /r (recover readable information). format: Formats a volume with a filesystem, erasing existing data; used to prepare drives for use. diskpart: Command-line disk partitioning tool for creating, deleting, extending, or assigning partitions and volumes. md and rmdir: md (mkdir) creates directories; rmdir removes empty directories (use /s to remove directories with contents).
Example
Run chkdsk /f on a volume that reports filesystem errors; schedule for reboot if it is the system drive.

How Disk, File, Informational, and OS Management Commands works
These commands are used by technicians to inspect and perform basic repairs on filesystems, gather identity and version information, manage local accounts, and refresh or report Group Policy. Examples include running chkdsk to fix filesystem errors, using robocopy for large data migrations, and running sfc to repair protected system files.
Example
Use robocopy to mirror a user profile to a backup location before imaging a machine.
Concept 3
Common confusion
Learners sometimes run destructive commands (format, diskpart) without confirming target disks. Emphasize verifying disk numbers in diskpart before issuing partition commands and always backing up data before destructive operations.
Example
Run gpresult /r to confirm whether a local policy is applied after a configuration change.
Concept 4
Core 2 (220-1202) question cues
Which command would you use to repair protected system files? (sfc /scannow); Which command displays the Windows build number? (winver); Which tool copies files and preserves attributes with mirroring options? (robocopy).
Example
Run chkdsk /f on a volume that reports filesystem errors; schedule for reboot if it is the system drive.

Q1.A technician is troubleshooting this situation: Run chkdsk /f on a volume that reports filesystem errors; schedule for reboot if it is the system drive. What should they identify?
Q2.A support ticket includes this clue: Use robocopy to mirror a user profile to a backup location before imaging a machine. Which concept is being tested?
Q3.An A+ support scenario describes this situation: Run gpresult /r to confirm whether a local policy is applied after a configuration change. Which answer fits best?
