A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-5Operating Systems

An administrator needs a command-line utility that can scan and repair an NTFS volume while it stays online, with the volume becoming briefly unavailable only during the consistency-restore phase. Which tool should be used?

Format-Volume cmdletFormat-Volume is a PowerShell cmdlet used to format a volume, not to repair an existing one.
formatformat initializes a volume and erases data; it does not scan and repair an existing volume.
self-healing NTFSSelf-healing NTFS runs automatically in the background for minor corruption and is not something an administrator invokes as a command-line tool.
chkdskCorrect · your answerCorrect: chkdsk is designed exactly for this scan-and-repair scenario while minimizing downtime.

Correct.

Checked against learn.microsoft.com, August 2026

Concept

NTFS provides both an automatic background repair feature and an invokable repair utility for larger corruption events.

Why D

chkdsk is the command-line utility that scans and repairs NTFS volumes while keeping them online, with unavailability limited to the consistency-restore phase.

Source

For more significant file system corruption, the chkdsk utility can scan and repair NTFS volumes while keeping them online, minimizing downtime. The only period the volume might be unavailable is during the phase required to restore data consistency.
