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

Existing customers continue to use the current stage (e.g., prod), which is integrated with the old Lambda version. The new stage (e.g., test) can point to the new Lambda version without affecting the production stage. B) Eliminated - routing even 10% of traffic to the new Lambda version could cause issues for customers if the new version has any problems. C) Eliminated - This approach introduces an extra Lambda function to filter requests, increasing complexity. D) Eliminated - Creating a new API Gateway involves replicating configurations like authorizers, throttling, and endpoints. Maintaining two separate API Gateways adds long-term management overhead.

How not C

It's hands-down A.

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

A is the correct answer.

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

Why not B? There is canary testing in Lambda Functions

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 As a newer version of the lambda function is deployed with the necessary changes, a new stage of the API Gateway can be used ot test the changes of the lambda function.

A : create new API stage (add stage) - correct D: crew new API Gateway (create new one) - incorrect

A is correct. Why the "correct answer" is always wrong? What's the point?

A is ok according to my perspective.

A's true

A is true

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.

The answer is A
