AWS Certified Solutions Architect – Associate (SAA-C02) — Question 157

A solutions architect is designing the storage architecture for a new web application used for storing and viewing engineering drawings. All application components will be deployed on the AWS infrastructure.
The application design must support caching to minimize the amount of time that users wait for the engineering drawings to load. The application must be able to store petabytes of data. Which combination of storage and caching should the solutions architect use?

Answer options

• A. Amazon S3 with Amazon CloudFront
• B. Amazon S3 Glacier with Amazon ElastiCache
• C. Amazon Elastic Block Store (Amazon EBS) volumes with Amazon CloudFront
• D. AWS Storage Gateway with Amazon ElastiCache

Correct answer: A

Explanation

The correct answer is A because Amazon S3 can store large amounts of data and works seamlessly with Amazon CloudFront, which provides caching to improve loading times. Options B and D do not provide the necessary caching capabilities for a web application, while option C, while it includes CloudFront, does not efficiently handle petabyte-scale storage as effectively as S3.
