CompTIA Linux+ XK0-006 (V8) Practice Question

You created a systemd service named backup.service that should run a shell script once each night. After starting it you run:

$ systemctl status backup.service
● backup.service - Daily Backup Job
   Loaded: loaded (/etc/systemd/system/backup.service; enabled; vendor preset: disabled)
   Active: active (exited) since Wed 2025-07-30 04:02:15 EDT; 5min ago
  Process: 458 ExecStart=/usr/local/bin/backup.sh (code=exited, status=0/SUCCESS)

Which statement correctly explains what this output means?

  • The status output shows the backup script exited with an error, so the unit is currently in a failed state.

  • The service is a long-running daemon that is still running in the background and will restart automatically if its PID terminates.

  • The backup script ran once, exited with status 0, and systemd now shows the unit as active (exited) even though no process is running.

  • Because vendor preset is disabled, the service is actually disabled and will not start automatically on the next boot.
