Exam AWS Certified Developer Associate topic 1 question 46 discussion

C. Create one API Gateway with multiple stages with one Lambda function with multiple aliases.

C is the answer

C) Correct - API Gateway allows you to create multiple stages (e.g., dev, test, prod) within a single API Gateway. You can use a single Lambda function and deploy multiple versions of it using aliases. An alias in AWS Lambda allows you to point to specific versions of the Lambda function. For instance, you can have dev, test, and prod aliases. With this approach, you only need to manage one API Gateway and one Lambda function, and the environment configurations are handled by stages (in API Gateway) and aliases (in Lambda).

Correct answer is C

Indeed with all of you, C is the correct one. First of all we need a lambda function with different versions. Then we have to create a lambda alias for each enviroment (dev, test, live for example) and make sure that each alias has the correct version associated. API Gateway side, we can create one stage for each environment as well and use a variable in order to solve at runtime the right environment

I dont really understand, why it is supposed to be C. Multiple stages for the api gateway ok. But a lambda with multiple aliases does not make sense go me. This would be the same lambda just with different names. But for Prod, dev and staging you would need different lambdas with different code, because it does not make any sense to have different stages if the code is the same?

C. D is doable but is not the easiest way, as you have to if else based on @PathVariable
