AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A CloudOps engineer is configuring Amazon CloudWatch to scale an Auto Scaling group. The group must launch one additional EC2 instance whenever the average CPUUtilization metric stays above 70 percent for 5 consecutive minutes. The solution must work without relying on EventBridge rules, Lambda functions, or other custom code. Which type of action should the engineer attach to the CloudWatch alarm to meet these requirements?

  • Specify a Systems Manager Automation document that uses the EC2:Run command to start a new instance.

  • Attach the ARN of a scaling policy associated with the Auto Scaling group.

  • Publish the alarm state to an Amazon SNS topic that triggers a Lambda function to add capacity.

  • Use an EC2 recovery action ARN so the instance restarts when the threshold is breached.
