Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 82

Which two are true about offloading backups to a physical standby database in a Data Guard environment?

Answer options

• A. The standby database must be registered in an RMAN catalog after the primary database has been registered.
• B. The standby database cannot be registered in an RMAN catalog if the primary database has not been registered.
• C. Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.
• D. The standby database must be registered in an RMAN catalog before the primary database has been registered.

Correct answer: B, C

Explanation

Option B is correct because the registration of the primary database is a prerequisite for adding the standby database to the RMAN catalog. Option C is also accurate since backups of the standby control file can be used for restoring the primary's control file when taken from the appropriate catalog. Options A and D are incorrect because they misrepresent the order and requirements for RMAN registration in relation to the primary database.
