Oracle Database Administration II — Question 109

Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)

Answer options

• A. Online Redo Log backups can be created while connected to the root container.
• B. Control file backups can be created while connected to the root container.
• C. The BACKUP TABLESPACE command can back up a PDB tablespace even if RMAN is connected to CDB$ROOT.
• D. Archived Redo Log backups can be created while connected to an application root CDB.
• E. Control file backups can be created while connected to a nonroot container.

Correct answer: B, C

Explanation

Option B is correct because control file backups can indeed be created while connected to the root container. Option C is also correct as the BACKUP TABLESPACE command can back up a PDB tablespace from CDB$ROOT. The other options are incorrect because online redo log backups cannot be created from the root container, archived redo log backups are not limited to application roots, and control file backups from nonroot containers do not apply to the question's context.
