Question 5

You had an outage in yourapplication 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?

A. Open OCI Console, select File Storage Service, find the snapshot you created and click restore. B. 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. C. Open OCI Console, select File Storage Service, find the shared storage, then click onsnapshot and 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: C

Question 13

You are the Solutions Architect of a large company and are tasked with migrating all your services to Oracle Cloud Infrastructure. As part of this, you first design a Virtual Cloud Network (VCN) with a public subnet and a private subnet.
