AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A SysOps team created a Bash script that clears application cache and restarts a service. When CPU utilization on an Amazon EC2 instance stays above 90% for 5 minutes, the team wants Amazon CloudWatch to invoke Systems Manager Automation to run this script on the affected instance. Which solution meets the requirement with the least operational overhead?

  • Add the Bash script to the EC2 user-data field and schedule a cron job inside the instance; set the CloudWatch alarm to reboot the instance to force the script to run.

  • Create a custom SSM Automation document of type Automation that includes a single aws:runCommand step referencing the AWS-RunShellScript command document with the Bash script inline, and configure the CloudWatch alarm to start this runbook against the instance.

  • Develop an AWS Lambda function that executes the script by using the SSM send-command API, and have the CloudWatch alarm invoke the function.

  • Configure a State Manager association that runs the Bash script with the AWS-RunShellScript document and set the CloudWatch alarm to publish an SNS notification that triggers the association.
