SOA-C03 Question #34: Real Exam Question with Answer & Explanation

Question

A company runs an application on an Amazon EC2 instance. The application uses a MySQL database. The EC2 instance has a General Purpose SSD (gp3) Amazon EBS volume attached. The company wants to perform load testing using a new MySQL database created from an EBS snapshot of the production instance. The new database must perform as similarly as possible to production. Which solution will meet these requirements in the LEAST amount of time?

Options

• AUse Amazon EBS fast snapshot restore (FSR) to create a new General Purpose SSD volume
• BUse Amazon EBS fast snapshot restore (FSR) to create a new Provisioned IOPS SSD volume
• CUse Amazon EBS standard snapshot restore to create a new General Purpose SSD volume from
• DUse Amazon EBS standard snapshot restore to create a new Provisioned IOPS SSD volume

Explanation

Amazon EBS snapshots are stored in Amazon S3, and standard restores can experience higher latency until data blocks are fully retrieved. Fast Snapshot Restore (FSR) eliminates this latency by ensuring that all blocks are immediately available at full performance. Because the production environment uses a General Purpose SSD (gp3) volume, creating the test database on the same volume type ensures performance characteristics are as similar as possible. Using FSR significantly reduces restore time and allows load testing to begin Provisioned IOPS volumes would introduce different performance characteristics and unnecessary cost. Standard snapshot restore would delay testing due to gradual block hydration. Therefore, using FSR with the same EBS volume type is the fastest and most accurate solution.
