During a DR test, a company must restore recent EBS snapshots to a new EC2 instance in another Availability Zone and immediately validate that the restored volumes deliver their full provisioned performance. Which configuration will provide the required performance as quickly as possible?

The correct option ensures immediate full performance by enabling EBS Fast Snapshot Restore (FSR) in the target Availability Zone. FSR pre-provisions the snapshot data to an available state, eliminating the typical "warming up" period where restored volumes might experience degraded performance as data is lazily loaded from S3. Creating new EBS volumes from these FSR-enabled snapshots in the target AZ and attaching them to the EC2 instance directly fulfills the requirement for immediate full provisioned performance. The second option is incorrect because enabling FSR in the original AZ does not benefit restorations in a different target AZ. FSR is AZ-specific. The third option is incorrect because merely specifying Provisioned IOPS on snapshots doesn't guarantee immediate full performance upon restoration; the volume still needs to be "warmed up" without FSR. The fourth option is incorrect because setting Provisioned IOPS on existing volumes before snapshotting doesn't inherently make the restored volumes immediately performant without FSR. The performance characteristic is captured, but the restoration process itself still needs FSR to avoid latency.
