AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An operations team created an Amazon CloudWatch composite alarm that enters the ALARM state when any of three underlying metric alarms breach. The team attempted to attach an EC2 Auto Scaling policy to the composite alarm so that additional instances launch automatically, but the console prevented the configuration. Which approach will allow the alarm to trigger the scaling action while following AWS best practices?

  • Enable action suppression on the composite alarm to allow EC2 Auto Scaling actions to be configured.

  • Replace the composite alarm with a standard metric alarm that uses a metric math expression combining the three metrics, then attach the Auto Scaling policy.

  • Create an Amazon EventBridge rule that matches the composite alarm's state change to ALARM and set the Auto Scaling policy as the rule's target.

  • Convert the composite alarm to an anomaly detection alarm and then attach the Auto Scaling policy.
