Deriving a systemd mount-unit name | LPIC-1 101-500 Exam original practice question

104.3Basic

Create a systemd mount unit for /data/backup.

Derive the unit filename from the mount-point path.

Which filename is appropriate?

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

data/backup.mount: Incorrect. A leading slash is not retained as data/ in the unit filename.
mount-data-backup.service: Incorrect. This is not the systemd mount-unit naming convention.
backup.data.mount: Incorrect. The components are in the wrong order.
data-backup.mount: Correct. /data/backup maps to data-backup.mount.
