AWS Certified SysOps Administrator – Associate — Question 424

A company runs an application that uses a MySQL database on an Amazon EC2 instance. The EC2 instance has a General Purpose SSD Amazon Elastic Block
Store (Amazon EBS) volume. The company made changes to the application code and now wants to perform load testing to evaluate the impact of the code changes.
A SysOps administrator must create a new MySQL instance from a snapshot of the existing production instance. This new instance needs to perform as similarly as possible to the production instance.
Which restore option meets these requirements?

Answer options

• A. Use EBS fast snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot.
• B. Use EBS fast snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot.
• C. Use EBS snapshot restore to create a new General Purpose SSD EBS volume from the production snapshot.
• D. Use EBS snapshot restore to create a new Provisioned IOPS SSD EBS volume from the production snapshot.

Correct answer: A

Explanation

To ensure the load test is accurate, the test database must use the same General Purpose SSD volume type as the production database, ruling out Provisioned IOPS options. Standard EBS snapshot restoration experiences 'lazy loading' latency on first access, which would skew performance test results. Utilizing EBS fast snapshot restore (FSR) delivers instant, full performance from the moment of creation, matching the production instance's characteristics.
