Question

A company hosts a production database on an Amazon Elastic Block Store (Amazon EBS) backed Amazon EC2 instance. As part of an annual disaster recovery exercise, the company needs to restore recent EBS snapshots to a new EC2 instance in a second Availability Zone.

After the snapshots are restored to EBS volumes, the resulting volumes must deliver all of their provisioned performance. The company must perform validation tests on the restored data as quickly as possible.

Which configuration will meet these requirements?

A. Enable EBS fast snapshot restore (FSR) on the snapshots for the second Availability Zone. Create new EBS volumes in the second Availability Zone from the snapshots. Attach the new EBS volumes to a new EC2 instance.
B. Enable EBS fast snapshot restore (FSR) on the snapshots for the current Availability Zone. Create new EBS volumes in the second Availability Zone from the snapshots, Attach the new EBS volumes to a new EC2 instance.
C. Specify Provisioned IOPS on the snapshots, Create new EBS volumes in the second Availability Zone from the snapshots. Attach the new EBS volumes to a new EC2 instance.
D. Specify Provisioned IOPS on the existing EBS volumes. Create the snapshots. After the snapshots are completed, create new EBS volumes in the second Availability Zone from the snapshots. Attach the new EBS volumes to a new EC2 instance.

Answer

A. Enable EBS fast snapshot restore (FSR) on the snapshots for the second Availability Zone. Create new EBS volumes in the second Availability Zone from the snapshots. Attach the new EBS volumes to a new EC2 instance.

Explanation

This configuration utilizes the EBS fast snapshot restore (FSR) feature to ensure that the restored EBS volumes in the second Availability Zone deliver their full provisioned performance immediately after restoration, allowing for rapid validation tests on the restored data.

Here’s how it works:

  1. Enable FSR on the EBS snapshots for the second Availability Zone. This pre-warms the storage resources required for the restored volumes in the target Availability Zone.
  2. Create new EBS volumes in the second Availability Zone from the snapshots with FSR enabled.
  3. Attach the newly created EBS volumes to a new EC2 instance in the second Availability Zone.

By enabling FSR on the snapshots for the second Availability Zone, the restored EBS volumes will have their full provisioned IOPS performance available immediately after the restoration process completes. This eliminates the need for an initial data loading phase, allowing the company to perform validation tests on the restored data as quickly as possible.

Other options are either not applicable or do not meet the requirements:

B. Enabling FSR on the snapshots in the current Availability Zone does not guarantee full performance for the restored volumes in the second Availability Zone.
C. Specifying Provisioned IOPS on the snapshots does not provide immediate full performance for the restored volumes, as there would still be an initial data loading phase.
D. Specifying Provisioned IOPS on the existing EBS volumes before taking snapshots does not impact the performance of the restored volumes in the second Availability Zone.
