Configuring and Managing Oracle Data Guard Broker

Examine the Fast-start Failover configuration:

Question Image

Which three statements are true?

Choose three
  • A The observer is not running.
  • B If the primary database is unreachable, the observer will wait 30 seconds before initiating a failover unless the primary database becomes reachable again.
  • C The configuration operates in Maximum Performance mode.
  • D The configuration operates in Maximum Availability mode.
  • E A failover will be initiated immediately if a corrupted control file is detected.
Explanation

The observer reconnects to an unreachable primary for the configured 30-second threshold before initiating fast-start failover. A 30-second Fast-Start Failover Lag Limit applies to a maximum-performance configuration. Because the Corrupted Controlfile health condition is enabled, its detection initiates fast-start failover without waiting for the failover threshold, provided the target is eligible to accept the failover.
