Question 9 of 10

One correct answer

lab-backup.service is already making a backup (`activating`), and you type `sudo systemctl start lab-backup.service`. What happens?

The command waits for the current run to end and starts no new backup.
A second backup starts, in parallel with the first.
systemctl answers at once with an error that the service is busy.
