Elastic Block Store Quiz
Currently a company makes use of EBS snapshots to back up their EBS Volumes. As a part of the business continuity requirement, these snapshots need to be made available in another region. How can this be achieved?
A. Directly create the snapshot in the other region.
B. Create Snapshot and copy the snapshot to new region.
C. Copy the snapshot to an S3 bucket and then enable Cross-Region Replication for thebucket.
D. Copy the EBS Snapshot to an EC2 instance in another region.
B. Create Snapshot and copy the snapshot to new region.
AWS Documentation mentions the following:
A snapshot is constrained to the region where it was created. After you create a snapshot of an EBS volume, you can use it to create new volumes in the same region. For more information, follow the link on Restoring an Amazon EBS Volume from a Snapshot below. You can also copy snapshots across regions, making it possible to use multiple regions for geographical expansion, data center migration, and disaster recovery.

Option C is incorrect. Because, the snapshots which we are taking from the EBS are stored in AWS managed S3. We don’t have the option to see the snapshot in S3. Hence, option C can’t be the correct answer.
