Which command creates a daily backup task using the Scheduler at 02:00?

• A. /system scheduler add name=nightly-backup start-time=02:00 interval=1d on-event=\"/system backup save name=nightly\"
• B. /system scheduler add name=nightly-saver start-time=02:00 interval=1d on-event=\"/system backup save name=nightly\"
• C. /system scheduler add name=nightly-backup start-time=03:00 interval=1d on-event=\"/system backup save name=nightly\"
• D. /system scheduler add name=nightly-backup start-time=02:00 interval=1w on-event=\"/system backup save name=nightly\"

Answer: (A)

Scheduling a daily task at a fixed time uses the start-time to set when it runs, interval set to 1d for a daily repetition, and on-event to execute the backup command. This command defines a task named nightly-backup, runs at 02:00 every day, and executes /system backup save name=nightly, which creates the nightly backup file at that time. That combination—02:00 start time, daily interval, and the backup command—matches the requirement precisely. The other options diverge by using a different time (03:00), a weekly interval (1w), or only changing the task name without affecting the actual timing and action, so they don’t meet the stated goal as cleanly.
