[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company has a three-tier image-sharing application. The application uses an Amazon EC2 instance for the front-end layer, another EC2 instance for the application layer, and a third EC2 instance for a MySQL database. A solutions architect must design a scalable and highly available solution that requires the least amount of change to the application.
Which solution meets these requirements?

  • A. Use Amazon S3 to host the front-end layer and AWS Lambda functions for the application layer. Move the database to an Amazon DynamoDB table and use Amazon S3 to store and serve users' images.
  • B. Use load-balanced Multi-AZ AWS Elastic Beanstalk environments for the front-end and the application layer. Move the database to an Amazon RDS instance with multiple read replicas to serve users' images.
  • C. Use Amazon S3 to host the front-end layer and a fleet of Amazon EC2 instances in an Auto Scaling group for the application layer. Move the database to a memory optimized instance type to store and serve users' images.
  • D. Use load-balanced Multi-AZ AWS Elastic Beanstalk environments for the front-end layer and the application layer. Move the database to an Amazon RDS Multi-AZ DB instance. Use Amazon S3 to store and serve users' images.
