View the Exhibit.
A Symmetric RAC and Physical Standby Database configuration is set up for a high availability requirement matching the one in the exhibit with the primary using ‘maximum availability’ protection mode.
Which two benefits are there for each primary instance in sending its redo to a corresponding standby instance, rather than having all the primary instances sending redo to the same standby apply instance? (Choose two.)
A.
If the redo receive load is spread across multiple receiving instances then the primary redo transport is less likely to become a bottleneck.
B.
Multiple standby instances allow the redo to be applied more quickly by the standby apply instance after the redo has already arrived from the primary.
C.
The workloads of the archive processes on the standby instances would be balanced, thereby allowing load balancing across the cluster where the standby resides.
D.
The services on the primary would be symmetric allowing performance on each instance to be equal in the event of a switchover or failover to the standby database.
E.
Multiple standby instances allow the redo to be written to standby redo logs more quickly than just using a single receiving instance by reducing commit time on the primary instances.
