What should a technician attempt FIRST to resolve missing files in a home directory on a Linux server?

• A. mount /home
• B. Check file permissions
• C. Restart the NFS service
• D. Run a file recovery tool

Answer: (A)

Mounting the /home directory should be the first step to resolve missing files on a Linux server because the home directory is typically a separate filesystem that needs to be mounted for access. If the /home directory is not mounted, users will not see any of their files or subdirectories, which can lead to the misunderstanding that files are missing. By mounting the /home directory, the technician can verify whether the relevant filesystem containing the user home directories has been properly attached and is accessible. Other options such as checking file permissions or restarting the NFS service could be necessary steps after ensuring that the filesystem itself is mounted. If the home directory is not mounted, checking permissions or trying to recover files would not yield any results, as the system wouldn't have access to the actual directory structure or files. Similarly, running a file recovery tool would only be warranted if it was confirmed that the files were indeed missing from an accessible filesystem, which is not the case if the mounting issue is at play.
