Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 183 discussion

C and D should be correct. Given that "The development team plans to test a small percentage of traffic that is directed to new updates before the team commits to a full deployment of the application." then Option D makes more sense than Option E.

CD is the correct answer.

I will got A & D D is nice and clear no debates For A - https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-automated-tests.html#:~:text=You%20can%20use%20the%20sam%20local%20invoke%20command%20to%20manually%20test%20your%20code%20by%20running%20Lambda%20functions%20locally.%20With%20the%20AWS%20SAM%C2%A0CLI%2C%20you%20can%20easily%20author%20automated%20integration%20tests%20by%20first%20running%20tests%20against%20local%20Lambda%20functions%20before%20deploying%20to%20the%20AWS%20Cloud.

C. Enable gradual deployments through AWS SAM templates: Gradual deployments allow you to safely deploy your application while exposing new versions to only a portion of your traffic. This approach is ideal for testing new updates in a production environment without impacting all users. AWS SAM supports the configuration of deployment preferences directly within the SAM template. D. Set the deployment preference type to Canary10Percent30Minutes. Use hooks to test the deployment: The Canary deployment type is suitable for gradually introducing a new version of the Lambda function. In this case, "Canary10Percent30Minutes" means that 10% of the traffic will be directed to the new version for 30 minutes. If no issues are detected, the rest of the traffic is shifted to the new version. The use of hooks allows for automated tests to run against the new deployment, ensuring its stability before full traffic shift.

A: test code during deploy https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-automated-tests.html D: Canary, to deploy a small percentage

C. Enable gradual deployments through AWS SAM templates. D. Set the deployment preference type to Canary10Percent30Minutes. Use hooks to test the deployment.

The correct answers are (C) and (E). (C) is the most important step because it allows you to deploy new Lambda function updates to a small percentage of your traffic. (E) is the second most important step because it allows you to test new Lambda function updates using hooks.
