AWS Certified SysOps Administrator – Associate (legacy) — Question 730

A user has launched an EC2 instance. The user is planning to setup the CloudWatch alarm. Which of the below mentioned actions is not supported by the
CloudWatch alarm?

Answer options

• A. Notify the Auto Scaling launch config to scale up
• B. Send an SMS using SNS
• C. Notify the Auto Scaling group to scale down
• D. Stop the EC2 instance

Correct answer: A

Explanation

CloudWatch alarms can trigger scaling policies for Auto Scaling groups, execute EC2 instance actions like stop or terminate, and send notifications via Amazon SNS. They cannot directly target or notify an Auto Scaling launch config, as it is a configuration template rather than an active operational resource.
