AWS Certified SysOps Administrator – Associate — Question 214

A company recently deployed MySQL on an Amazon EC2 instance with a default boot volume. The company intends to restore a 1.75 TB database. A SysOps administrator needs to provision the correct Amazon Elastic Block Store (Amazon EBS) volume. The database will require read performance of up to 10,000 IOPS and is not expected to grow in size.

Which solution will provide the required performance at the LOWEST cost?

Answer options

• A. Deploy a 2 TB Cold HDD (sc1) volume.
• B. Deploy a 2 TB Throughput Optimized HDD (st1) volume.
• C. Deploy a 2 TB General Purpose SSD (gp3) volume. Set the IOPS to 10,000.
• D. Deploy a 2 TB Provisioned IOPS SSD (io2) volume. Set the IOPS to 10,000.

Correct answer: C

Explanation

The correct answer is C because a 2 TB General Purpose SSD (gp3) volume can be provisioned to meet the required IOPS at a lower cost compared to the other options. Options A and B do not provide sufficient IOPS, while option D, while capable, is more expensive than necessary for the performance requirement.
