83. A technician is troubleshooting a computer that is not booting properly. The technician suspects a corrupted system file. Which of the following tools should the technician use to repair the issue?
Answer: A
The technician should use sfc /scannow to repair the corrupted system file.
Using the command sfc /scannow allows the technician to scan and repair corrupted system files that could be preventing the computer from booting properly.
A) sfc /scannow
This option is correct as the sfc (System File Checker) tool specifically scans for and repairs corrupted system files. Running this command can restore missing or corrupted files that are essential for the operating system, thus addressing the booting issue.
B) chkdsk
While chkdsk is a useful tool for checking the integrity of the file system and hard drive, it primarily focuses on disk errors rather than system file corruption. It may help with some booting issues related to disk faults, but it does not directly repair system files.
C) msconfig
The msconfig tool is used for system configuration and managing startup programs and services. It does not have the capability to repair corrupted system files, making it ineffective for resolving the specific issue of a computer not booting due to file corruption.
D) diskpart
Diskpart is a command-line utility used for disk partitioning and management. It does not address corrupted system files, and using it would not resolve the booting problems arising from file corruption.
Conclusion
The correct choice, sfc /scannow, directly targets the repair of corrupted system files, which is critical in this scenario. Other options, such as chkdsk, msconfig, and diskpart, do not focus on system file integrity and therefore do not adequately address the technician's concern regarding booting issues caused by file corruption.
