AWS Certified SysOps Administrator - Associate SOA-C02 — Topic 1 Question 76

Question

An application runs on Amazon EC2 instances in an Auto Scaling group. Following the deployment of a new feature on the EC2 instances, some instances were marked as unhealthy and then replaced by the Auto Scaling group. The EC2 instances terminated before a SysOps administrator could determine the cause of the health status changes. To troubleshoot this issue, the SysOps administrator wants to ensure that an AWS Lambda function is invoked in this situation. How should the SysOps administrator meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Add a lifecycle hook to the Auto Scaling group to invoke the Lambda function through Amazon EventBridge (Amazon CloudWatch Events). AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures.
