Oracle Database 12c: Advanced Administration — Question 29

You execute the RMAN commands:
RMAN> BACKUP VALIDATE DATABASE;
RMAN> RECOVER CORRUPTION LIST;
Which task is performed by these commands?

Answer options

• A. Corrupted blocks, if any, are repaired in the backup created.
• B. Only those data files that have corrupted blocks are backed up.
• C. Corrupted blocks in the data files are checked and repaired before performing the database backup.
• D. The database is checked for physically corrupt blocks and any corrupted blocks are repaired.

Correct answer: C

Explanation

The correct answer is C because the command BACKUP VALIDATE DATABASE checks for corruption in the data files and RECOVER CORRUPTION LIST repairs any corrupted blocks before the backup occurs. Options A, B, and D are incorrect because they either misrepresent the nature of the backup process or suggest actions that are not part of the commands executed.
