Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 59

Which three are true about using RMAN in a Data Guard environment?

Answer options

• A. A recovery catalog is required when RMAN is used to take backups from a logical standby database in a Data Guard configuration if you plan to recover the primary using those backups.
• B. Backups of archived redo logs taken on a physical standby are interchangeable with a primary.
• C. A recovery catalog is required when RMAN is used to take backups from a physical standby database if you plan to recover the primary using those backups.
• D. Backups of control files taken on a physical standby are not interchangeable with a primary.
• E. Backups of data files taken on a physical standby are interchangeable with a primary.

Correct answer: B, C, E

Explanation

Option B is correct because archived redo logs from a physical standby can indeed be used for recovery on the primary. Option C is also accurate since a recovery catalog is required for RMAN backups from a physical standby intended for primary recovery. Option E is true as data file backups from a physical standby can be used interchangeably with the primary. Option A is incorrect because the recovery catalog is not needed for logical standbys in this scenario, and option D is wrong since control file backups are also not interchangeable.
