AWS Certified SysOps Administrator – Associate — Question 152

A SysOps administrator is testing an application that is hosted on five Amazon EC2 instances. The instances run in an Auto Scaling group behind an Application Load Balancer (ALB). High CPU utilization during load testing is causing the Auto Scaling group to scale out. The SysOps administrator must troubleshoot to find the root cause of the high CPU utilization before the Auto Scaling group scales out.

Which action should the SysOps administrator take to meet these requirements?

Answer options

• A. Enable instance scale-in protection.
• B. Place the instance into the Standby state.
• C. Remove the listener from the ALB.
• D. Suspend the Launch and Terminate process types.

Correct answer: D

Explanation

The correct action is to suspend the Launch and Terminate process types, which will prevent the Auto Scaling group from scaling out while the administrator investigates the high CPU utilization issue. The other options do not directly address the need to halt scaling activities or could disrupt the load balancing and availability of the application.
