AWS Certified Solutions Architect – Associate (SAA-C02) — Question 39

A company wants to migrate a high performance computing (HPC) application and data from on-premises to the AWS Cloud. The company uses tiered storage on premises with hot high-performance parallel storage to support the application during periodic runs of the application, and more economical cold storage to hold the data when the application is not actively running.
Which combination of solutions should a solutions architect recommend to support the storage needs of the application? (Choose two.)

Answer options

• A. Amazon S3 for cold data storage
• B. Amazon Elastic File System (Amazon EFS) for cold data storage
• C. Amazon S3 for high-performance parallel storage
• D. Amazon FSx for Lustre for high-performance parallel storage
• E. Amazon FSx for Windows for high-performance parallel storage

Correct answer: A, D

Explanation

The correct answers are A and D. Amazon S3 is ideal for cost-effective cold data storage, making it suitable for the application's inactive periods. Amazon FSx for Lustre provides the high-performance parallel storage required during intensive application runs, while the other options either do not meet the performance needs or are not suited for cold storage.
