1Z0-1123-25 Question 118
Select 2Your organization plans to implement near real-time replication of a 1 TB block volume from the Ashburn region to the Phoenix region for disaster recovery. The source block volume is currently attached to a running Compute instance in Ashburn, and it is encrypted using Oracle-managed keys. Which two actions must you perform to properly configure and enable replication for this block volume?
- A
Create an empty block volume in Phoenix of matching size before starting replication, so the replication process can synchronize properly.
- B
From the block volume details page in Ashburn, select 'Create Replication,' specify Phoenix as the target region, and confirm the configuration.
- C
Detach the block volume from the running Compute instance before initiating replication to ensure data consistency on the secondary site.
- D
Enable volume group replication on the compartment containing the block volume; this will automatically replicate all volumes within that compartment to Phoenix.
- E
Allow the replication to create the target volume automatically in Phoenix, because you are using Oracle-managed encryption keys and no additional key setup is required in the target region.
Show answer and explanation
Correct answers: B, E
Explanation
To set up OCI Block Volume Replication correctly, you configure it from the source volume in the OCI Console by selecting 'Create Replication' and choosing the target region. The replication feature automatically creates a corresponding volume in the target region, making manual creation of a volume unnecessary. For volumes encrypted with Oracle-managed keys, there's no need for additional key configuration in the target region. Refer to the official OCI documentation on Block Volume Replication (https://docs.oracle.com/en-us/iaas/Content/Block/Tasks/volumereplication.htm) for more details and best practices.
- A. Incorrect.
Incorrect. You do not need to manually create a block volume on the target side. Using the built-in replication feature automatically creates and manages the target volume.
- B. Correct.
Correct. Configuring block volume replication is done from the source volume's details page. You specify the target region (Phoenix), and the replication process handles volume creation in the target region.
- C. Incorrect.
Incorrect. Detaching the volume is not a requirement for replication. OCI block volume replication can replicate data while the volume is attached to a running instance.
- D. Incorrect.
Incorrect. Volume group replication is used to replicate a group of volumes together (including boot volumes). It does not automatically replicate all individual block volumes in a compartment unless they are explicitly part of that group.
- E. Correct.
Correct. When using Oracle-managed keys, you do not need to configure any additional encryption keys in the target region. The replication process will handle encryption with the same Oracle-managed key in Phoenix.
