Oracle Cloud Infrastructure 2019 Developer Associate — Question 8

You are responsible for creating and maintaining an enterprise application that consists of multiple storage volumes across multiple instances. 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. You can create clones of storage volumes one at a time
• B. You can group together multiple storage volumes in a volume group and create volume group backups
• C. You can create on-demand one-off backups of boot volumes, but not block volumes
• D. You can create on-demand one-off backups of block volumes, but not boot volumes

Correct answer: D

Explanation

The correct answer is D because on-demand one-off backups are specifically available for block volumes, allowing for efficient data protection. Options A and B are less efficient and do not take advantage of the capabilities of block volume backups. Option C is incorrect since it suggests that boot volumes can be backed up on demand, which is not applicable here.
