A desktop technician is performing maintenance on a Windows workstation that has been experiencing stability issues after a recent software installation. Company policy requires technicians to audit system file integrity and log any modified or corrupted protected files, but strictly prohibits making any automatic repairs or file replacements during the initial investigation phase. Which of the following command-line executions fulfills this requirement?

  1. sfc /verifyonlyAnswer
  2. B
    sfc /scannow
  3. C
    chkdsk /r
  4. D
    fsck -n

Answer

The command 'sfc /verifyonly' scans the integrity of protected system files without attempting any automated repairs.
The 'sfc /verifyonly' command instructs System File Checker to scan all protected system files for integrity issues and write the diagnostic outcome to logs without repairing or modifying any files, satisfying the audit-only policy requirement.

Step-by-Step Solution

1
Identify the primary administrative objective and constraints.
The requirement is to audit and log system file corruption while adhering to a strict no-repair restriction.
Administrative policy dictates that no system files should be modified during the initial diagnostic step.
2
Evaluate the appropriate command-line utility for system file verification.
System File Checker (sfc.exe) is the Windows utility designed to inspect protected system files.
Selecting SFC isolates system file validation from disk sector checks or third-party file operations.
3
Select the switch that restricts SFC to non-destructive auditing.
The /verifyonly flag scans all protected system files and outputs integrity violations without replacing modified files.
Using /verifyonly meets the exact policy criteria of reporting findings without executing automated repairs.
