[All AWS Certified Developer - Associate DVA-C02 Questions]

A company is developing an ecommerce application that uses Amazon API Gateway APIs. The application uses AWS Lambda as a backend. The company needs to test the code in a dedicated, monitored test environment before the company releases the code to the production environment.

Which solution will meet these requirements?

  • A. Use a single stage in API Gateway. Create a Lambda function for each environment. Configure API clients to send a query parameter that indicates the environment and the specific Lambda function.
  • B. Use multiple stages in API Gateway. Create a single Lambda function for all environments. Add different code blocks for different environments in the Lambda function based on Lambda environment variables.
  • C. Use multiple stages in API Gateway. Create a Lambda function for each environment. Configure API Gateway stage variables to route traffic to the Lambda function in different environments.
  • D. Use a single stage in API Gateway. Configure API clients to send a query parameter that indicates the environment. Add different code blocks for different environments in the Lambda function to match the value of the query parameter.

The answer is C - we should create multiple stages and different Lambdas that will be utilised based on API Gateway stages variables. https://docs.aws.amazon.com/apigateway/latest/developerguide/amazon-api-gateway-using-stage-variables.html

Selected Answer: C
Lambda functions for each environment: Creating separate Lambda functions for each environment helps to ensure that the code for testing in the test environment is isolated from the production code.

Selected Answer: C
C. Use multiple stages in API Gateway. Create a Lambda function for each environment. Configure API Gateway stage variables to route traffic to the Lambda function in different environments: This is the recommended approach. Using multiple stages in API Gateway (one for testing and one for production) allows for clear separation of environments. Having a dedicated Lambda function for each environment ensures isolation and reduces the risk of accidental changes impacting the production environment. API Gateway stage variables can be used to manage configurations specific to each stage, such as function names or other parameters.
