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.
