Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 42

Which three are true concerning database states after a successful switchover?

Answer options

• A. If the former primary database became a logical standby database it will be in mount state.
• B. The new primary database will be open read-write.
• C. The former primary database will always be open.
• D. If the former primary database became a logical standby database it will be open read-write.
• E. If the former primary database became a physical standby database it will always be open read-only.
• F. If the former primary database became a physical standby database it will be in the same state as the former physical standby database.

Correct answer: A, B, E

Explanation

The correct answers A, B, and E accurately describe the states of the databases after a switchover. A states that the former primary becomes a logical standby in mount state, B indicates that the new primary is open for read-write, and E states that the former primary as a physical standby is always read-only. Options C and D are incorrect as they misrepresent the states of the databases after the switchover.
