NEW QUESTION # 70
You have configured RMAN SBT channels to write backups to media.
You then take an RMAN backup by using this command:
Which three are true? (Choose three.)
- A. The control file is included in the self-contained archival backup.
- B. The data file backups in the self-contained archive backup are not considered obsolete for two years regardless of the retention policy.

- D. All archive logs created after this backup are kept for two years.
- E. The restore point is a label for the system change number (SCN) that will be saved two years after the archival backup was taken.
- F. The SPFILE is included in the self-contaied archival backup.
Answer: A,B,F
Explanation:
The restore point is a label for the SCN to which this archival backup can be restored and recovered , and is captured just after the data file backups complete. (F is wrong) Normal restore points are retained in the database for at least the number of days specified for the CONTROL_FILE_RECORD_KEEP_TIME initialization parameter (A incorrect)
- The control file autobackup that RMAN automatically makes when you use the backup .. keep command has a copy of the restore point (and also the spfile D and E are correct) KEEP - Specifies the backup as an archival backup, which is a self-contained backup that is exempt from the configured retention policy.
UNTIL TIME - Specifies the time until which the backup or copy must be kept (B correct)
