AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 236

Question

A company has a three-tier application for image sharing. 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?

Accepted Answer

Correct answer: D. The correct answer is D. Option 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. AWS Elastic Beanstalk provisions and manages the underlying environment for you with little operational effort. Amazon S3 provides durable, scalable object storage that is fully managed. Amazon RDS is a managed relational database that handles patching, backups and failover. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
