Question

A company is migrating its multi-tier on-premises application to AWS. The application consists of a single-node MySQL database and a multi-node web tier. The company must minimize changes to the application during the migration. The company wants to improve application resiliency after the migration. Which combination of steps will meet these requirements? (Choose two.)

Accepted Answer

Correct answer: A, C. The correct answer is A, C. Option A: Migrate the web tier to Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer. Option C: Migrate the database to an Amazon RDS Multi-AZ deployment. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. 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.
