AWS Certified Solutions Architect – Associate (SAA-C02) — Question 153

A solutions architect is designing the cloud architecture for a new application being deployed to AWS. The application allows users to interactively download and upload files. Files older than 2 years will be accessed less frequently. The solutions architect needs to ensure that the application can scale to any number of files while maintaining high availability and durability.
Which scalable solutions should the solutions architect recommend? (Choose two.)

Answer options

• A. Store the files on Amazon S3 with a lifecycle policy that moves objects older than 2 years to S3 Glacier.
• B. Store the files on Amazon S3 with a lifecycle policy that moves objects older than 2 years to S3 Standard-Infrequent Access (S3 Standard-IA)
• C. Store the files on Amazon Elastic File System (Amazon EFS) with a lifecycle policy that moves objects older than 2 years to EFS Infrequent Access (EFS IA).
• D. Store the files in Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data older than 2 years.
• E. Store the files in RAID-striped Amazon Elastic Block Store (Amazon EBS) volumes. Schedule snapshots of the volumes. Use the snapshots to archive data older than 2 years.

Correct answer: B

Explanation

Option B is correct because storing files on Amazon S3 with a lifecycle policy that transitions older files to S3 Standard-IA offers a cost-effective storage solution for infrequently accessed data while still providing high availability. Option A, while also viable, is typically used for archival storage, which may not align with the application's need for high accessibility of files. Options C, D, and E are less suitable due to higher costs and lower scalability compared to S3.
