1Z0-1072-25 Question 210
Single answerYou have an application spanning multiple block volumes in different availability domains. You create a volume group to perform a single backup of all these volumes simultaneously. However, when you initiate the volume group backup, it fails due to an error indicating that not all volumes are in the same availability domain. What is the best approach to resolve this issue so you can create a consistent backup of all volumes at once?
- A
Migrate all block volumes to the same availability domain, then recreate your volume group and initiate the backup again
- B
Change the block volume attachment types to iSCSI instead of paravirtualized attachments to allow cross-AD backups
- C
Use an Object Storage bucket and copy volume data into it before performing the volume group backup
- D
Add an additional volume group in each availability domain to replicate the existing group
Show answer and explanation
Correct answer: A
Explanation
In Oracle Cloud Infrastructure, volume groups allow you to perform single-point backups and clones of multiple block volumes that share the same lifecycle requirements. However, all block volumes in a single volume group must reside in the same availability domain (AD) for the backup to be consistent. When volumes span multiple ADs, you must migrate them to a single AD or create separate volume groups per AD. For more details, refer to the OCI Block Volume Service documentation on Volume Groups and Backup Best Practices.
- A. Correct.
Correct. Volume groups must have all their block volumes located in the same availability domain for a single-point backup to succeed. By relocating volumes to a single availability domain and then creating the volume group again, you can perform a consistent volume group backup.
- B. Incorrect.
Incorrect. Changing the attachment type does not circumvent the requirement that all volumes in a volume group must reside in the same availability domain for a single group backup to succeed.
- C. Incorrect.
Incorrect. Storing data in an Object Storage bucket is not equivalent to performing a volume group backup. While you can place discrete backups in Object Storage, it does not replace the cross-AD restriction for volume group backups.
- D. Incorrect.
Incorrect. Adding another volume group in each availability domain does not solve the single backup error. The requirement is that a single volume group for backup must contain volumes all in the same availability domain.
