Which statement is true about this configuration?

  • A The Close_by primary database instance forwards redo to the FS_inst Far Sync instance, which forwards the redo in turn to the Far_away physical standby database instance.
  • B The far sync instance will not forward redo to the Far_away physical standby because Fast-Start Failover is disabled.
  • C The far sync instance will not forward redo to the Far_away physical standby because the Protection mode is not MaxProtection.
  • D The Close_by primary database instance forwards redo to the Far_away physical standby directly and also sends redo to the FS_inst Far Sync instance.
  • E The FS_inst Far Sync instance forwards redo to the Far_away physical standby only if the Close_by primary database is not able to do so.
Explanation

The nested broker configuration layout represents a redo route from the primary database through the far sync instance to the physical standby database. A far sync instance receives redo from the primary and forwards it to the downstream physical standby. This forwarding is independent of Fast-Start Failover being disabled and is supported in MaxPerformance mode.
