1.5 Given a scenario, use the appropriate Microsoft command-line tools.
Objective 1.5 sits in Operating Systems, which carries 28% of the A+ Core 2 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
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?
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.
Now you: objective 1.5 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 2
A technician opens an elevated Command Prompt to format a new drive that will host .vhdx files larger than 1 TB. The volume needs a large File Record Segment and a 64 KB allocation unit size. Which command accomplishes this?
Sample question 2 of 2
A technician uses Windows PowerShell to format a volume that will host Data Deduplication and large files, following the recommended allocation unit size and File Record Segment support. Which command should the technician run?
