AWS Certified DevOps Engineer - Professional DOP-C02 — Topic 1 Question 70

Question

A company has an application that runs on a fleet of Amazon EC2 instances. The application requires frequent restarts. The application logs contain error messages when a restart is required. The application logs are published to a log group in Amazon CloudWatch Logs. An Amazon CloudWatch alarm notifies an application engineer through an Amazon Simple Notification Service (Amazon SNS) topic when the logs contain a large number of restart-related error messages. The application engineer manually restarts the application on the instances after the application engineer receives a notification from the SNS topic. A DevOps engineer needs to implement a solution to automate the application restart on the instances without restarting the instances. Which solution will meet these requirements in the MOST operationally efficient manner?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Configure an AWS Systems Manager Automation runbook that runs a script to restart the application on the instances. Configure an Amazon EventBridge rule that reacts when the CloudWatch alarm enters ALARM state. Specif... Amazon EventBridge routes events between services with rules, enabling event-driven, decoupled architectures. Amazon CloudWatch collects metrics, logs and alarms to monitor and react to operational health. AWS Config tracks resource configuration changes and evaluates compliance.
