AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A CloudOps engineer manages an Auto Scaling group of t3.small instances running a latency-sensitive REST API. The p95 request latency occasionally increases to several seconds even though the CloudWatch CPUUtilization metric never rises above 20%. During the same periods, the CPUCreditBalance metric falls to 0 for every instance. What is the most cost-effective change that resolves the performance issue?

  • Modify the launch template so the Auto Scaling group uses T3 Unlimited mode.

  • Convert the Auto Scaling group to run Spot Instances of the same t3.small instance type.

  • Add a scaling policy that doubles the desired capacity when CPUUtilization exceeds 60%.

  • Replace the t3.small instances with m6i.large instances in the launch template.
