Oracle Database 12c: Advanced Administration — Question 77

RMAN is configured to create backupset backups for your database. You issue the command to back up the database:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which two statements are true about the backup performed by the command?

Answer options

• A. Only the used blocks in the data files are backed up.
• B. It backs up all the data files and deletes obsolete backups after the backup is complete.
• C. It backs up only those archived log files that are not backed up at least once.
• D. It backs up all the archived log files and deletes the ones that were just backed up.
• E. It backs up all archived redo log files and online log files and deletes the archived log files after the backup is complete.

Correct answer: B, D

Explanation

The correct answer B states that all data files are backed up and obsolete backups are deleted afterward, which is true for the command issued. Option D is also correct as it indicates that all archived log files are backed up and the ones just backed up are deleted. Options A, C, and E do not accurately reflect the behavior of the command executed.
