LFCS Question #850: Real Exam Question with Answer & Explanation

Question

To allow a regular user account to mount and unmount a filesystem (for instance, a cdrom or floppy), which option need to be added to the corresponding line in /etc/fstab?

Options

• Anouidchk
• Balluser
• Cuser
• Dauto

Explanation

The user option in /etc/fstab permits any regular user to mount and unmount the specified filesystem, typically used for removable media like CD-ROMs or floppy drives.

Common mistakes.

• A. nouidchk is an obscure option related to NFS mounts and UIDs, not for general user mounting permissions.
• B. alluser is not a standard fstab mount option.
• D. auto causes the filesystem to be mounted automatically at boot time or when mount -a is run, but does not grant regular users mount/unmount privileges.

Concept tested. fstab mount options for user privileges
