A worked example

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

Operating SystemsEasy

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?

Correct.

The concept

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

Why this answer

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

  • Correct: chkdsk is designed exactly for this scan-and-repair scenario while minimizing downtime.
  • Bformat initializes a volume and erases data; it does not scan and repair an existing volume.
  • CSelf-healing NTFS runs automatically in the background for minor corruption and is not something an administrator invokes as a command-line tool.
  • DFormat-Volume is a PowerShell cmdlet used to format a volume, not to repair an existing one.
