AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An Auto Scaling group launches Amazon Linux 2 instances that run a Java application. Operations needs to collect memory utilization and the application's /var/log/app.log file, and they want to be able to change the collection settings without baking a new AMI or manually connecting to instances. What is the MOST maintainable way to deploy and manage the CloudWatch agent across all current and future instances?

  • Rely on default EC2 metrics and create a CloudWatch Logs subscription filter that streams /var/log/app.log to CloudWatch Logs.

  • Store the agent's JSON configuration as a Systems Manager Parameter and use a State Manager association with the AmazonCloudWatch-ManageAgent document to install and start the agent on all instances.

  • Bake the agent and its configuration into a custom AMI that the Auto Scaling group uses for all launches.

  • Add the agent's configuration file to user data and run amazon-cloudwatch-agent-ctl in the Auto Scaling group launch template.
