Question

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?

Accepted Answer

Correct answer: C. The correct answer is C. Option 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. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead.
