Upgrade Oracle DBA 11g to Oracle Database 12c — Question 53

Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2, both of which are open. RMAN is connected to the target database pdb2_1.
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which statement is true about the execution of this command to back up the database?

Answer options

• A. All data files belonging to pdb2_1 are backed up and all archive log files are deleted.
• B. All data files belonging to pdb2_1 are backed up along with the archive log files.
• C. Only the data files belonging to pdb2_ are backed up.
• D. This command gives an error because archive log files can be backed up only when RMAN is connected to the root database.

Correct answer: C

Explanation

The correct answer is C because the command will only back up the data files associated with the currently connected PDB, pdb2_1. Options A and B incorrectly suggest that archive logs will be deleted or backed up, which is not applicable here since RMAN is only targeting pdb2_1. Option D is also incorrect, as RMAN can back up archive logs while connected to a PDB, but it does not apply in this context.
