A company is designing a new multi-tier web application that consists of the following components: • Web and application servers that run on Amazon EC2 instances as part of Auto Scaling groups • An Amazon RDS DB instance for data storage A solutions architect needs to limit access to the application servers so that only the web servers can access them. Which solution will meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Deploy an Application Load Balancer with a target group that contains the application servers' Auto Scaling group. Configure the security group to allow only the web servers to access the application servers. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. An Application Load Balancer distributes HTTP/HTTPS traffic and supports path/host routing. A load balancer distributes traffic across targets in multiple AZs for availability and scale.
