AWS Certified Solutions Architect – Associate (SAA-C02) — Question 774

A solutions architect is helping a company design storage for a high performance computing (HPC) environment that is based on Amazon Linux. The workload stores and processes a large number of engineering drawings that require shared storage. The company needs a solution that can support hundreds of Amazon
EC2 instances. The solution also must provide sub-millisecond latencies.
Which solution meets these requirements?

Answer options

• A. Amazon EC2 instance store
• B. Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io2)
• C. Amazon Elastic File System (Amazon EFS)
• D. Amazon FSx for Lustre

Correct answer: D

Explanation

Amazon FSx for Lustre is a high-performance parallel file system designed specifically for HPC workloads, offering sub-millisecond latencies and concurrent access for hundreds of EC2 instances. Amazon EBS and EC2 instance stores do not support shared file access across hundreds of instances natively. Amazon EFS supports shared access but cannot match the parallel processing capabilities and low latency of FSx for Lustre for HPC workloads.
