AWS Certified Solutions Architect – Associate (SAA-C03) — Question 55

A company wants to migrate its on-premises application to AWS. The application produces output files that vary in size from tens of gigabytes to hundreds of terabytes. The application data must be stored in a standard file system structure. The company wants a solution that scales automatically. is highly available, and requires minimum operational overhead.
Which solution will meet these requirements?

Answer options

• A. Migrate the application to run as containers on Amazon Elastic Container Service (Amazon ECS). Use Amazon S3 for storage.
• B. Migrate the application to run as containers on Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon Elastic Block Store (Amazon EBS) for storage.
• C. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling group. Use Amazon Elastic File System (Amazon EFS) for storage.
• D. Migrate the application to Amazon EC2 instances in a Multi-AZ Auto Scaling group. Use Amazon Elastic Block Store (Amazon EBS) for storage.

Correct answer: C

Explanation

Option C is correct because Amazon Elastic File System (Amazon EFS) provides a scalable and highly available file storage solution that fits the requirement for a standard file system structure with automatic scaling. The other options either use storage solutions that do not meet the requirements for file system structure (like Amazon S3 and Amazon EBS) or do not leverage the automatic scaling capabilities of EFS.
