AWS Certified Solutions Architect – Associate (SAA-C02) — Question 292

A company wants to use high performance computing (HPC) infrastructure on AWS for financial risk modeling. The company's HPC workloads run on Linux. Each
HPC workflow runs on hundreds of AmazonEC2 Spot Instances, is short-lived, and generates thousands of output files that are ultimately stored in persistent storage for analytics and long-term future use.
The company seeks a cloud storage solution that permits the copying of on premises data to long-term persistent storage to make data available for processing by all EC2 instances. The solution should also be a high performance file system that is integrated with persistent storage to read and write datasets and output files.
Which combination of AWS services meets these requirements?

Answer options

• A. Amazon FSx for Lustre integrated with Amazon S3
• B. Amazon FSx for Windows File Server integrated with Amazon S3
• C. Amazon S3 Glacier integrated with Amazon Elastic Block Store (Amazon EBS)
• D. Amazon S3 bucket with a VPC endpoint integrated with an Amazon Elastic Block Store (Amazon EBS) General Purpose SSD (gp2) volume

Correct answer: A

Explanation

Amazon FSx for Lustre is a high-performance file system specifically optimized for fast processing of Linux-based workloads like HPC, and it natively integrates with Amazon S3 to read and write datasets directly. Amazon FSx for Windows File Server is designed for Windows environments, which does not match the Linux requirement. Amazon EBS volumes are block storage and cannot be natively shared across hundreds of concurrent EC2 instances in the same manner as a distributed FSx for Lustre file system.
