View the Exhibit and examine the RMAN commands.
Which statement describes the effect of a backup retention policy on the backup of a backup set?
A.
Either all the copies of a backup set are obsolete or none of them are as per the retention
policy.
B.
The copies of the backup will be reported as obsolete under a redundancy-based backup

C.
The copies of the backup will be reported as obsolete under a recovery window-based
backup retention policy.
D.
All the copies of the backup set are counted as one instance of a backup and will deleted
in backup set exceeds the redundancy-based backup retention policy.
Yes it is A, note in the Exhibit we see that we are talking aout the “recovery window retention policy”

you can see that it says ….
For a recovery window retention policy, either all of the copies of a backup set are obsolete, or none of them are. This point is easiest to grasp when viewing the output of the LIST and REPORT commands.
after some more consideration …

Effect of a Backup Retention Policy on Backups of Backups
For a backup retention policy based on redundancy, a backup set is counted as one instance of a backup. This statement is true even if there are multiple copies of the backup pieces that form the backup set, such as when a backup set has been backed up from disk to tape.
For a recovery window retention policy, either all of the copies of a backup set are obsolete, or none of them are. This point is easiest to grasp when viewing the output of the LIST and REPORT commands.
