AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A startup runs 50 Amazon Linux 2 instances across two VPCs. Operations must publish memory utilization and disk I/O metrics to Amazon CloudWatch and stream application logs, without opening SSH access or logging in to each host. Every instance already assumes an IAM role that includes AmazonSSMManagedInstanceCore and CloudWatchAgentServerPolicy. Which approach meets the requirements with the least operational effort?

  • Enable detailed monitoring on the EC2 instances and create a CloudWatch Logs subscription filter to ingest application logs.

  • Add a user-data script to each instance that runs the CloudWatch agent configuration wizard at boot and publishes metrics with PutMetricData.

  • Use AWS Systems Manager Run Command to install the CloudWatch unified agent on all instances, store a common agent configuration in Systems Manager Parameter Store, and start the agent fleet-wide.

  • Deploy the older CloudWatch Logs agent with an IAM instance profile and generate custom metrics later by querying logs with CloudWatch Logs Insights.
