AWS Certified Developer Associate DVA-C02 Practice Question

A development team has created a REST API in Amazon API Gateway with two stages: dev and prod. Both stages invoke the same AWS Lambda function. The team wants calls to the dev stage to invoke the dev alias of the function and calls to the prod stage to invoke the prod alias-without editing the API's integration settings whenever the API is promoted between stages.

Which API Gateway feature enables this behavior?

  • Create a separate custom domain name for each stage-alias combination.

  • Configure a stage variable that holds the Lambda alias and reference it in the integration URI.

  • Enable a canary deployment for the stage and route all traffic to the desired alias.

  • Attach a usage plan that maps requests from each stage to a different Lambda alias.
