AWS Certified SysOps Administrator – Associate (legacy) — Question 57

A company is running a new promotion that will result in a massive spike in traffic for a single application. The SysOps Administrator must prepare the application and ensure that the customers have a great experience. The application is heavy on memory and is running behind an AWS Application Load Balancer (ALB).
The ALB has been pre-warmed, and the application is in an Auto Scaling group.
What built-in metric should be used to control the Auto Scaling group's scaling policy?

Answer options

• A. RejectedConnection Count
• B. Request CountPerTarget
• C. CPUUtilization
• D. MemoryUtilization

Correct answer: C

Explanation

The correct answer is C, CPUUtilization, because it is a common metric used for scaling policies in Auto Scaling groups. While MemoryUtilization is important for memory-heavy applications, it is not a built-in metric for ALB, making options A, B, and D less suitable in this context.
