Topic 1 Question 238
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?
Enable instance scale-in protection.
Place the instance into the Standby state.
Remove the listener from the ALB.
Suspend the Launch and Terminate process types.

you have to suspend the launch and termination of instances in order to troubleshoot the issues.

You can put an instance that is in the InService state into the Standby state, update or troubleshoot the instance, and then return the instance to service. Instances that are on standby are still part of the Auto Scaling group, but they do not actively handle load balancer traffic.

Placing the instance into the Standby state (answer B) would remove the instance from the ALB target group, which would prevent it from receiving traffic. The answer is D, because you need Suspend the Launch and Terminate process so that you can troubleshoot to find the root cause of the high CPU utilization before the Auto Scaling group scales out.
