Answers
D.
Use an API Gateway stage variable to configure the Lambda function alias Republish PROD and create a new stage for development Create API Gateway stage variables for PROD and DEV stages Point each stage variable to the PROD Lambda function alias and to the DEV Lambda function alias
Suggested answer: D

Explanation:

API Gateway Stages:Stages in API Gateway represent distinct environments (like PROD and DEV) allowing different configurations.

Stage Variables:Stage variables store environment-specific information, including Lambda function aliases.

Ease of Management:This solution offers a straightforward way to manage different Lambda function versions across environments.
