AWS Certified Solutions Architect – Associate (SAA-C03) — Question 622

A company runs a website that stores images of historical events. Website users need the ability to search and view images based on the year that the event in the image occurred. On average, users request each image only once or twice a year. The company wants a highly available solution to store and deliver the images to users.

Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Store images in Amazon Elastic Block Store (Amazon EBS). Use a web server that runs on Amazon EC2.
• B. Store images in Amazon Elastic File System (Amazon EFS). Use a web server that runs on Amazon EC2.
• C. Store images in Amazon S3 Standard. Use S3 Standard to directly deliver images by using a static website.
• D. Store images in Amazon S3 Standard-Infrequent Access (S3 Standard-IA). Use S3 Standard-IA to directly deliver images by using a static website.

Correct answer: D

Explanation

Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is the ideal storage class for data that is accessed less frequently but requires rapid access when requested, offering lower storage costs than S3 Standard. Hosting the images as a static website directly from S3 provides a highly available solution without the ongoing compute costs and management overhead of Amazon EC2 instances with EBS or EFS. Therefore, S3 Standard-IA combined with static website hosting is the most cost-effective and highly available choice.
