Question 96

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

    Correct Answer: C, D

    Flashback Database permits a primary database that was disabled after failover to be reinstated as a standby. This is because the flashback feature allows the primary database to be rolled back to a specific point in time before the failover occurred, making it possible to reinstate it as a standby database. Additionally, Flashback Database permits a physical standby database to be converted to a snapshot standby database. Flashback must be enabled to facilitate the conversion between physical and snapshot standby databases, as it allows changes made during the snapshot standby mode to be undone, returning the database to its previous physical standby state.
