Which AWS service allows you to define alarms that automatically roll back a CodeDeploy deployment when a CloudWatch metric breaches a threshold?
Answer: CloudWatch Alarms with CodeDeploy rollback triggers
CodeDeploy supports automatic rollback when a CloudWatch Alarm you associate with the deployment group enters the ALARM state.
In a canary deployment on AWS Lambda using CodeDeploy, what does the 'Canary10Percent5Minutes' configuration mean?
Answer: 10% of traffic shifts immediately, remaining 90% shifts after 5 minutes
Canary10Percent5Minutes shifts 10% of traffic to the new version immediately, waits 5 minutes, then shifts the remaining 90%.
Which X-Ray feature helps identify the slowest components in a distributed application by visualizing latency across service calls?
Answer: Service map with latency histograms
X-Ray service maps display response time distributions and highlight high-latency nodes across microservice calls.
When running integration tests in CodePipeline, which action provider lets you invoke an AWS Lambda function as a test step?
Answer: AWS Lambda invoke action
CodePipeline's Lambda invoke action lets you call a Lambda function directly as a pipeline action, returning success or failure to the pipeline.
A team wants zero-downtime deployments for an ECS Fargate service. Which deployment controller type achieves this using weighted target groups?
Answer: CODE_DEPLOY with blue/green
CODE_DEPLOY deployment controller for ECS uses two target groups with weighted routing to shift traffic with zero downtime.
Which CloudWatch feature enables you to automatically detect anomalous patterns in metric data without manually setting static thresholds?
Answer: CloudWatch Anomaly Detection
CloudWatch Anomaly Detection uses ML to model expected metric behavior and alerts when values deviate significantly.
In AWS CodeBuild, which test report type natively integrates to display pass/fail results directly in the CodeBuild console?
Answer: JUnit XML and Cucumber JSON test reports
CodeBuild Test Reports support JUnit XML and Cucumber JSON formats, rendering pass/fail breakdowns natively in the console.
