BCJC is running Oracle DB workloads on AWS. Currently, they are running the Oracle RAC (Real Application Cluster) configuration on the AWS public cloud. You`ve been tasked with configuring snapshots on the RAC cluster to enable durability. What is the best method for configuring snapshots to become backups eventually?

Answer options:

A.Create manual snapshots of the RDS backup and write a script that runs the manual snapshot.
B.Enable Multi-AZ failover on the RDS RAC cluster to reduce the RPO and RTO in the event of disaster or failure.
C.Create a script that runs snapshots against the EBS volumes to create backups.
D.Enable automated backups on the RDS RAC cluster; enable auto snapshot copy to a backup region to reduce RPO and RTO.

Answer – C
Currently, Oracle Real Application Cluster (RAC) is not supported as per the AWS documentation. However, you can deploy scalable RAC on Amazon EC2 using the recently-published tutorial and Amazon Machine Images (AMI). So, to create the snapshots (for an eventual backup), you need to save a point-in-time view of the EC2 that is deployed for RAC in the form of a snapshot and create a script that runs snapshots against the EBS volumes, and run it against the snapshot.
Options A, B, and D are all incorrect because RDS does not support Oracle RAC.Option C is CORRECT because Oracle RAC is supported via the deployment using Amazon EC2. Hence, for the data backup, you can create a script that takes the snapshots of the EBS volumes.
