An application uses MySQL on an EC2 instance with a General Purpose SSD (gp) EBS volume. After code changes, you need to create a new MySQL instance from a snapshot of production for realistic load testing. Which restore option will produce a new volume that behaves most like the current production volume?

Correct answer: Use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot..
Why this is the answer
The correct option is to use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot. This approach ensures that the new volume has the same performance characteristics (General Purpose SSD) as the original production volume, which is crucial for realistic load testing. Additionally, using EBS fast snapshot restore pre-warms the volume, meaning all data blocks are immediately available, preventing the performance degradation that can occur with standard restores as data is accessed for the first time. Using Provisioned IOPS SSD (io1/io2) volumes would provide higher performance than the original gp volume, making the load test results unrealistic. Standard snapshot restore, while creating the correct volume type, would result in a "cold" volume where performance might be inconsistent until all data is accessed, which is not ideal for immediate, consistent load testing.
