AWS Certified SysOps Administrator – Associate — Question 111

A SysOps administrator is reviewing AWS Trusted Advisor recommendations. The SysOps administrator notices that all the application servers for a finance application are listed in the Low Utilization Amazon EC2 Instances check. The application runs on three instances across three Availability Zones. The SysOps administrator must reduce the cost of running the application without affecting the application’s availability or design.

Which solution will meet these requirements?

Answer options

• A. Reduce the number of application servers.
• B. Apply rightsizing recommendations from AWS Cost Explorer to reduce the instance size.
• C. Provision an Application Load Balancer in front of the instances.
• D. Scale up the instance size of the application servers.

Correct answer: B

Explanation

The correct answer is B, as applying rightsizing recommendations allows the administrator to optimize costs by adjusting the instance sizes based on actual utilization without compromising availability. Option A would reduce availability by lowering the server count, C does not address cost reduction directly, and D would increase costs by scaling up the existing instances.
