OFFLINE BACKUPS MUST BE DONE IN MOUNT MODE

4. þ B, D, and F. Offline backups must be done in mount mode. This is

the only backup type for a noarchivelog mode database, but it can be

incremental.

ý A, C, and E. A is wrong because the database must be mounted, or RMAN

won’t be able to connect to its repository or find the location of the datafiles.

C is wrong because an IMMEDIATE shutdown is clean—it is only an ABORT

that would cause problems. E is wrong because an archivelog mode database

can certainly be backed up offline—it just isn’t necessary.
