What are the two advantages of RMAN Block Media Recovery (BMR) over file-level recovery?()
A

BMR lowers the mean time to recover (MTTR).

B

BMR supports point-in-time recovery of individual data blocks.

C

BMR enables you to use incremental backups for block recovery.

D

BMR enables recovery even when the database is not mounted or open.

E

BMR enables you to use proxy backups to perform block media recovery.

F

BMR enables increased availability of data during recovery because the data file requires a recovery can remain online.
