AWS Certified Solutions Architect – Associate (SAA-C03) — Question 31

A company's website uses an Amazon EC2 instance store for its catalog of items. The company wants to make sure that the catalog is highly available and that the catalog is stored in a durable location.
What should a solutions architect do to meet these requirements?

Answer options

• A. Move the catalog to Amazon ElastiCache for Redis.
• B. Deploy a larger EC2 instance with a larger instance store.
• C. Move the catalog from the instance store to Amazon S3 Glacier Deep Archive.
• D. Move the catalog to an Amazon Elastic File System (Amazon EFS) file system.

Correct answer: D

Explanation

The correct answer is D because Amazon Elastic File System (Amazon EFS) provides a durable and highly available storage solution that can be accessed concurrently by multiple EC2 instances. The other options either do not provide the necessary durability or availability, such as Amazon ElastiCache for Redis (A), which is meant for caching and not long-term storage, or Amazon S3 Glacier Deep Archive (C), which is designed for infrequent access and has longer retrieval times.
