The infrastructure team at your company is designing a Maximum Availability Architecture for your Oracle databases consisting of a four-node RAC cluster for the primary database with flashback database configured, and a two-node cluster for the standby database with flashback database configured.
The standby database is in a separate location in another city. There are six services configured and clustered ASM is used for storage on the primary and the standby
Which two statements are true concerning this architecture? (Choose two.)
A.
It protects against site failures after a switchover to the standby database.
B.
It protects against instance failures after a switchover to the standby database.
C.
It does not protect against node failures in case of a failover to the standby database.
D.
It can help to prevent data corruptions before they happen on both the primary and the standby databases.
E.
It does not provide for continuous availability of services in the event of a switchover to the standby database.
