SAA-C03 Question #519: Real Exam Question with Answer & Explanation

Question

A company runs an application that uses Docker containers in an on-premises data center. The application runs on a container host that stores persistent data files in a local volume. Container instances use the stored persistent data. The company wants to migrate the application to fully managed AWS services. Which solution will meet these requirements?

Options

• AUse Amazon Elastic Kubernetes Service (Amazon EKS) with self-managed nodes. Attach an
• BUse Amazon Elastic Container Service (Amazon ECS) with the AWS Fargate launch type. Create
• CUse Amazon Elastic Container Service (Amazon ECS) with the AWS Fargate launch type. Create
• DUse Amazon Elastic Container Service (Amazon ECS) with the Amazon EC2 launch type. Create

Explanation

The company wants to move from an on-premises Docker environment to fully managed AWS services with persistent storage. The best fit is: Amazon ECS with AWS Fargate launch type: This is a serverless container orchestration solution where AWS manages the underlying infrastructure, removing the need to manage EC2 or Kubernetes nodes. Amazon EFS (Elastic File System): This is a fully managed, scalable, and shared file system for use with ECS tasks. It supports persistent storage for containers, replacing the local volumes used on-premises. This combination (ECS + Fargate + EFS) is fully managed and requires no manual server Option A uses EKS with self-managed nodes, which is not fully managed. Option C (DynamoDB) is for structured key-value storage, not for persistent file storage. Option D uses ECS with EC2 launch type, which is not serverless and requires managing
