Oracle Cloud Infrastructure 2020 Architect Associate — Question 54

You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple compute instances in Oracle
Cloud Infrastructure (OCI).
The storage volumes include boot volumes and block volumes for your data storage. You need to create backups of these storage volumes in the most time- efficient manner.
How can you meet this requirement?

Answer options

• A. Create clones of all boot volumes and block volumes one at a time.
• B. Create on-demand full backups of boot volumes, and copy data in block volumes to Object Storage using OCI CLI.
• C. Create on-demand full backups of block volumes, and create custom images from the boot volumes.
• D. Group together multiple storage volumes in a volume group and create volume group backups.

Correct answer: D

Explanation

The correct answer is D because grouping storage volumes into a volume group allows for simultaneous backups, which is more time-efficient. Options A and B involve backing up volumes one at a time or copying data separately, which is slower. Option C focuses on block volumes and images but does not optimize the backup process across multiple volumes.
