Question 1 of 48

Domain: Design High-Performing Architectures

The engineering team at a data analytics company has observed that its flagship application functions at its peak performance when the underlying Amazon Elastic Compute Cloud (Amazon EC2) instances have a CPU utilization of about 50%. The application is built on a fleet of Amazon EC2 instances managed under an Auto Scaling group. The workflow requests are handled by an internal Application Load Balancer that routes the requests to the instances.
As a solutions architect, what would you recommend so that the application runs near its peak performance state?

Configure the Auto Scaling group to use target tracking policy and set the CPU utilization as the target metric with a target value of 50%

Configure the Auto Scaling group to use a Amazon Cloudwatch alarm triggered on a CPU utilization threshold of 50%

Configure the Auto Scaling group to use simple scaling policy and set the CPU utilization as the target metric with a target value of 50%

Configure the Auto Scaling group to use step scaling policy and set the CPU utilization as the target metric with a target value of 50%
