DVA-C02 › Troubleshooting and Optimization
This domain covers diagnosing and tuning workloads on AWS: Lambda logging and invocation failures, CodeBuild/CodePipeline build errors, ECS Fargate migrations, and event-driven processing with S3 and DynamoDB. Questions present a symptom, a console or CLI observation, and ask for the most likely cause or the best fix, so you must reason from service behavior rather than memorized limits.
