AWS Certified SysOps Administrator – Associate (legacy) — Question 415

A database running on Amazon EC2 requires sustained IOPS performance.
Which kind of Amazon EBS volume should an Administrator choose for this solution?

Answer options

• A. Cloud HDD
• B. General Purpose SSD
• C. Provisioned IOPS SSD
• D. Throughput Optimized HDD

Correct answer: C

Explanation

Provisioned IOPS SSD volumes are specifically engineered to deliver low-latency, sustained IOPS performance for I/O-intensive database workloads on Amazon EC2. General Purpose SSD volumes are cost-effective but do not guarantee the same high, consistent IOPS performance under heavy sustained loads. HDD-based volumes, such as Throughput Optimized HDD and Cloud HDD, are optimized for throughput rather than IOPS and are not suitable for high-performance database needs.
