AWS Certified Solutions Architect – Professional (SAP-C02) — Question 333
A company has a legacy application that runs on multiple NET Framework components. The components share the same Microsoft SQL Server database and communicate with each other asynchronously by using Microsoft Message Queueing (MSMQ).
The company is starting a migration to containerized .NET Core components and wants to refactor the application to run on AWS. The .NET Core components require complex orchestration. The company must have full control over networking and host configuration. The application's database model is strongly relational.
Which solution will meet these requirements?
Answer options
- A. Host the INET Core components on AWS App Runner. Host the database on Amazon RDS for SQL Server. Use Amazon EventBiridge for asynchronous messaging.
- B. Host the .NET Core components on Amazon Elastic Container Service (Amazon ECS) with the AWS Fargate launch type. Host the database on Amazon DynamoDUse Amazon Simple Notification Service (Amazon SNS) for asynchronous messaging.
- C. Host the .NET Core components on AWS Elastic Beanstalk. Host the database on Amazon Aurora PostgreSQL Serverless v2. Use Amazon Managed Streaming for Apache Kafka (Amazon MSK) for asynchronous messaging.
- D. Host the NET Core components on Amazon Elastic Container Service (Amazon ECS) with the Amazon EC2 launch type. Host the database on Amazon Aurora MySQL Serverless v2. Use Amazon Simple Queue Service (Amazon SQS) for asynchronous messaging.
Correct answer: D
Explanation
Amazon ECS with the Amazon EC2 launch type satisfies the requirement for complex container orchestration while granting full control over the underlying host configuration and networking, unlike serverless options like Fargate or App Runner. Amazon Aurora MySQL Serverless v2 provides a highly scalable, strongly relational database that fits the application's data model. Finally, Amazon SQS is the ideal AWS-native queueing service to replace MSMQ for asynchronous messaging between components.
