Which statement about the RMAN restore and recovery is wrong?

The restored data files can use archived logs and online logs to complete the recovery.

Restore (restore) refers to the previously generated backup set, get one or more objects, and then set to restore these objects.

Recovery (recovery) is a database that is consistent with the given point in time to ensure that this database can be opened.

Usually restored content lags behind the latest database SCN, so you need to ensure consistency through the restoration of the database.

The restored data files can use archived logs and online logs to complete the recovery.
