QUESTION 141

QUESTION 142
You have configured RMAN SBT channels to write backups to media.
You then take an RMAN backup by using this command:

They are never considered obsolete by RMAN.

They can optionally be written to a fast recovery area (FRA).

All archive logs are retained after an archival backup is taken, until the next archival backup is taken of the same database.

Archive logs are retained if they are necessary to allow the database to be recovered to a consistent state when an archival backup is restored.

The SPFILE is included in the archival backup.

Use of a recovery catalog is always required to support the creation and use of archival backups. G)The ARCHIVAL attribute for a backup overrides the RMAN retention policy.
