AWS Certified Solutions Architect – Associate (SAA-C03) — Question 999

A company is planning to deploy a business-critical application in the AWS Cloud. The application requires durable storage with consistent, low-latency performance.

Which type of storage should a solutions architect recommend to meet these requirements?

Answer options

• A. Instance store volume
• B. Amazon ElastiCache for Memcached cluster
• C. Provisioned IOPS SSD Amazon Elastic Block Store (Amazon EBS) volume
• D. Throughput Optimized HDD Amazon Elastic Block Store (Amazon EBS) volume

Correct answer: C

Explanation

Provisioned IOPS SSD Amazon Elastic Block Store (Amazon EBS) volumes are designed to provide highly durable block storage with consistent, low-latency performance for I/O-intensive, business-critical applications. In contrast, Instance store volumes are ephemeral and lose data when the instance stops, while Throughput Optimized HDDs are intended for large, sequential workloads rather than low-latency performance. Amazon ElastiCache is an in-memory caching service and does not serve as a durable block storage solution.
