A company needs to clone large amounts of production data (stored on Amazon EBS volumes attached to EC2 instances) into a test environment in the same AWS Region. Changes to the cloned data must not affect production. The software requires consistently high I/O performance. A solutions architect must minimize the time required to clone the data. Which solution meets these requirements?

Correct answer: Take EBS snapshots of the production volumes. Enable the EBS fast snapshot restore feature on the snapshots. Restore the snapshots into new EBS volumes and attach the new volumes to EC2 instances in the test environment..
Why this is the answer
The correct solution leverages EBS snapshots with Fast Snapshot Restore (FSR) to quickly create new, fully provisioned EBS volumes in the test environment. FSR ensures that the restored volumes immediately deliver their maximum provisioned performance, which is crucial for the requirement of consistently high I/O. Cloning data via snapshots creates independent copies, preventing changes in the test environment from affecting production. Incorrect options: Restoring to EC2 instance store volumes is problematic because instance store is ephemeral and data would be lost if the instance stops or terminates. EBS Multi-Attach allows multiple instances to attach to a single volume, but it's not designed for cloning data into a separate test environment without affecting the original. Attaching production volumes directly to test instances would violate the requirement that changes to cloned data must not affect production. Creating and initializing new EBS volumes before restoring from snapshots would add an unnecessary step and potentially delay the availability of data, as the initialization process can take time.
