AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An operations engineer must ensure that when the root EBS volume of any Amazon EC2 instance reaches 90 percent disk utilization, the volume is automatically expanded and the file system is resized. The engineer wants a fully managed, code-free solution that minimizes ongoing maintenance. Which approach will meet these requirements across all instances?

  • Place the instances in an Auto Scaling group and configure a scaling policy that launches larger instance types with bigger root volumes when the alarm fires.

  • Trigger an AWS Lambda function from the CloudWatch alarm that calls the ModifyVolume API and runs a shell command to resize the file system.

  • Create an AWS Config custom rule that detects volumes over 90 percent utilization and invokes Systems Manager Run Command to execute a disk-resize script on the instance.

  • Create a CloudWatch alarm for 90 percent disk utilization and an EventBridge rule that targets the AWS-ExtendEbsVolume Systems Manager Automation runbook.
