1Z0-1123-25 Question 115
Select 2Your organization hosts critical database block volumes in the Phoenix region and needs to maintain near real-time copies in the Ashburn region for disaster recovery. Which TWO steps must you perform to properly set up OCI Block Volume Replication so that the replica remains synchronized in the Ashburn region?
- A
Create a block volume replica in the Phoenix region, specifying the Ashburn region as the target and configuring replication parameters to match your RPO.
- B
Attach the volume replica to a compute instance in the Ashburn region as soon as the replication is created, ensuring live writes are continually relayed.
- C
Update IAM policies to include permissions required for volume replication across regions, such as 'manage volume-replication' in your tenancy or compartments.
- D
Place both source and destination block volumes in the exact same compartment to ensure cross-region replication completes successfully.
Show answer and explanation
Correct answers: A, C
Explanation
When setting up OCI Block Volume Replication, you must create the replication from the source region (Phoenix) to the destination region (Ashburn) and ensure all required IAM permissions are in place. Attaching the replicated volume to a compute instance is optional and depends on your usage scenario. The compartments for source and destination volumes do not need to be identical in order for replication to succeed. For additional guidance, refer to the official OCI documentation: https://docs.oracle.com/en-us/iaas/Content/Block/Concepts/blockvolumereplication.htm
- A. Correct.
Correct. Configuring the volume replica in the source region and specifying the target region is essential for setting up block volume replication. You must define replication parameters (e.g., RPO windows) that suit your business requirements.
- B. Incorrect.
Incorrect. Attaching a replica to a compute instance in the target region is not required to enable or maintain replication. You only need to attach it in Ashburn if you want to use or boot from that replica, but it� not mandatory for the replication process itself.
- C. Correct.
Correct. You must grant the appropriate IAM permissions to allow block volume replication. Without the necessary 'manage volume-replication' or similar privileges, OCI cannot create or maintain replicas across regions.
- D. Incorrect.
Incorrect. You can replicate a block volume to a different compartment or region. It is not mandatory that both volumes reside in the same compartment. The replication configuration itself handles cross-region transfers.
