Question

A company hosts a monolithic web application on an Amazon EC2 instance. Application users have recently reported poor performance at specific times. Analysis of Amazon CloudWatch metrics shows that CPU utilization is 100% during the periods of poor performance. The company wants to resolve this performance issue and improve application availability. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

Accepted Answer

Correct answer: A, E. The correct answer is A, E. Option A: Use AWS Compute Optimizer to obtain a recommendation for an instance type to scale vertically. Option E: Create an Auto Scaling group and an Application Load Balancer to scale horizontally. 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. This option delivers the requirement at the lowest cost.
