CompTIA A+ Core 2 (220-1202)Operating SystemsEasy
A technician is troubleshooting a Windows 10 workstation that is experiencing issues with system stability and performance. The technician suspects that the operating system's core files might be corrupted or missing. Which command-line utility should the technician use to scan and attempt to repair these critical system files?
- Achkdsk /f
- Bsfc /scannow
- Crobocopy C:\Source D:\Destination
- Dipconfig /all
Show answer & explanationAnswer & explanation
Correct answer: B. sfc /scannow
The System File Checker (sfc) command with the /scannow option is specifically designed to scan all protected system files for corruption and replace incorrect versions with correct Microsoft versions.
Why the other options are wrong
- A. chkdsk is used to check a disk for errors, not system file corruption.
- C. robocopy is used for robust file copying, not system file repair.
- D. ipconfig /all displays detailed network configuration information.
