A company is using AWS CodePipeline to automate its release pipeline. AWS CodeDeploy is being used in the pipeline to deploy an application to Amazon Elastic Container Service (Amazon ECS) using the blue/green deployment model. The company wants to implement scripts to test the green version of the application before shifting traffic. These scripts will complete in 5 minutes or less. If errors are discovered during these tests, the application must be rolled back. Which strategy will meet these requirements?

AfterAllowTestTraffic lifecycle event in the hooks section will not shift the whole traffic to the green application but only a small percentage of traffic to the newly deployed version. C is the answer

CodeDeploy Blue/Green deployments, the AfterAllowTestTraffic hook is triggered after the test traffic redirection to the new version (Green) is set. Additional verification, testing, or other custom actions can be automated by executing Lambda functions at this time.
