Which three are prerequisites for enabling Fast-Start Failover?
To enable Fast-Start Failover, three prerequisites need to be considered. Firstly, the Fast-Start Failover target standby database must receive REDO directly from the primary database to ensure it has the most recent transaction data. Secondly, Flashback Database must be enabled on both the primary and the Fast-Start Failover target standby database to ensure recovery to a prior point in time in case of failure, thus maintaining data integrity. Thirdly, the Data Guard environment must be managed by the Data Guard Broker, which automates the failover process and ensures smooth management of Data Guard configurations.
Fast Start Failover can't be with Fast Start SYNC or Cascade Flashback is necessary in both. DGMRL is necessary in Fast Start Failover configuration
B, D, F - prior to 12.2 Starting with Oracle Database 12c Release 2, the maximum protection mode can be used, but with two or more standby databases
D is wrong.
:) for 12.1 is D ok, wrong is for 12.2
