Selected Answer: C
This approach involves creating a single API Gateway and a single Lambda function. Within the API Gateway, you can create multiple stages, each corresponding to a different environment (development, test, production). Similarly, for the Lambda function, you can create multiple aliases, each pointing to a different version of the Lambda function that corresponds to each environment. This setup allows for clear separation of environments within the same set of resources. It simplifies deployment and management by reducing the number of resources and also provides an easy way to promote changes from one environment to another.

Selected Answer: C
API Gateway A stage in API Gateway represents a deployment of your API. You can have separate stages for development, test, and production. Each stage can have its own settings, such as stage variables, custom domains, and caching configurations. Lambda function Each alias can point to a specific version of your Lambda function. This allows you to promote versions through different environments without changing the function's Amazon Resource Name (ARN) in your API Gateway.
