Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 69

Which two are true concerning the configuring of Flashback database in a Data Guard environment? (Choose two.)

Answer options

• A. It enables the use of far sync instances.
• B. It is a prerequisite for the use of Fast Start Failover.
• C. It permits a primary database that was disabled after failover to be reinstated as a standby.
• D. It permits a physical standby database to be converted to a snapshot standby database.
• E. It is required in order for a snapshot standby database to be converted to a physical database.

Correct answer: A, B

Explanation

The correct answers, A and B, are true because Flashback database functionality is essential for using far sync instances and is a prerequisite for Fast Start Failover. The other options are incorrect as they either misrepresent the purpose of Flashback in relation to standby databases or state requirements that are not related to Flashback functionality.
