AWS Certified Solutions Architect – Associate (SAA-C03) — Question 914

A company has a web application that has thousands of users. The application uses 8-10 user-uploaded images to generate AI images. Users can download the generated AI images once every 6 hours. The company also has a premium user option that gives users the ability to download the generated AI images anytime.

The company uses the user-uploaded images to run AI model training twice a year. The company needs a storage solution to store the images.

Which storage solution meets these requirements MOST cost-effectively?

Answer options

• A. Move uploaded images to Amazon S3 Glacier Deep Archive. Move premium user-generated AI images to S3 Standard. Move non-premium user-generated AI images to S3 Standard-Infrequent Access (S3 Standard-IA).
• B. Move uploaded images to Amazon S3 Glacier Deep Archive Move all generated AI images to S3 Glacier Flexible Retrieval.
• C. Move uploaded images to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA). Move premium user-generated AI images to S3 Standard. Move non-premium user-generated AI images to S3 Standard-Infrequent Access (S3 Standard-IA).
• D. Move uploaded images to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA). Move all generated AI images to S3 Glacier Flexible Retrieval.

Correct answer: A

Explanation

Amazon S3 Glacier Deep Archive is the most cost-effective storage tier for user-uploaded images because they are only retrieved twice a year for model training. Premium users require immediate, on-demand access to their generated images, making S3 Standard the correct choice, while non-premium users downloading every 6 hours can be served immediately and cost-effectively via S3 Standard-IA. Options utilizing S3 Glacier Flexible Retrieval are incorrect because Glacier retrieval times (minutes to hours) would disrupt the immediate download experience required by the users.
