Oracle Cloud Infrastructure 2019 Developer Associate — Question 41

You had an outage in your application caused by the loss of a shared volume provisioned by File Storage Service (FSS). At this point, you need to restore the data from a snapshot you created of the FSS. What are the steps to restore the data?

Answer options

• A. Access the directory where the shared volume is mounted, then cd into .snapshot folder, find the snapshot folder you want to recover and use cp or rsync tool to copy the files to the original location.
• B. Open OCI Console, select File Storage Service, find the shared storage, then click on snapshot and restore.
• C. Open OCI Console, select File Storage Service, find the snapshot you created and click restore.
• D. Access the directory, where you mounted the shared volume, then cd into .snapshot folder and find the snapshot folder you want to recover and rename that folder to the original folder name.

Correct answer: B

Explanation

The correct answer is B because it outlines the proper process for restoring a snapshot directly through the OCI Console interface, which is the most straightforward method. Options A and D involve manual file copying and renaming, which are not the standard procedures for restoring snapshots in FSS. Option C, while close, is incomplete as it does not mention the initial step of selecting the shared storage before restoring the snapshot.
