Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 461
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A developer published a change to a new version of an AWS Lambda function. To test the change, the developer must route 50% of the traffic to the new version and 60% of the traffic to the current version.

What is the MOST operationally efficient way to meet this requirement?

  • A. Create two Amazon Route 53 records that use a simple routing policy to route traffic to the different versions of the Lambda function. Create another Route 53 record that uses a weighted routing policy to route 50% of the traffic to each simple routing record. Test the Lambda function by using the weighted routing record.
  • B. Create an Amazon API Gateway API with a POST method that is integrated with the Lambda function. Add a stage variable that includes the version of the Lambda function. Add a canary release that will override the version variable 50% of the time. Deploy and test the Lambda function through the API Gateway stage.
  • C. Create a Lambda function alias. Set the weight to 50% for the current version and 50% for the new version. Set the event source mappings for the Lambda function to point to the alias.
  • D. Update the event source mappings for the Lambda function. In the mappings, set the weight to 50% for the current version and 50% for the new version.

La manera más sencilla es usar un alias de Lambda con una configuración de enrutamiento ponderado (routing weights) para distribuir el tráfico entre versiones.
