Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 99 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 99
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company has an AWS Lambda function that processes incoming requests from an Amazon API Gateway API. The API calls the Lambda function by using a Lambda alias. A developer updated the Lambda function code to handle more details related to the incoming requests. The developer wants to deploy the new Lambda function for more testing by other developers with no impact to customers that use the API.

Which solution will meet these requirements with the LEAST operational overhead?

  • A. Create a new version of the Lambda function. Create a new stage on API Gateway with integration to the new Lambda version. Use the new API Gateway stage to test the Lambda function.
  • B. Update the existing Lambda alias used by API Gateway to a weighted alias. Add the new Lambda version as an additional Lambda function with a weight of 10%. Use the existing API Gateway stage for testing.
  • C. Create a new version of the Lambda function. Create and deploy a second Lambda function to filter incoming requests from API Gateway. If the filtering Lambda function detects a test request, the filtering Lambda function will invoke the new Lambda version of the code. For other requests, the filtering Lambda function will invoke the old Lambda version. Update the API Gateway API to use the filtering Lambda function.
  • D. Create a new version of the Lambda function. Create a new API Gateway API for testing purposes. Update the integration of the new API with the new Lambda version. Use the new API for testing.

the request is `Which solution will meet these requirements with the LEAST "operational overhead"?`, Therefore solution C is too crazy and the operation will be complex

Option A requires creating a new stage on API Gateway, which might increase the operational overhead and complexity of managing multiple stages.

There is no need for us to create an all-new API Gateway in order to test the newer version of lambda. As a newer version of the lambda function is deployed with the necessary changes, a new stage of the API Gateway can be used ot test the changes of the lambda function.

In my perspective, A is the correct answer and a pretty typical pattern; I'm not sure why C was chosen, but testing in production is not a smart practice.
