A company has a serverless application that uses an Amazon API Gateway API to invoke an AWS Lambda function. A developer creates a fix for a defect in the Lambda function code. The developer wants to deploy this fix to the production environment. To test the changes, the developer needs to send 10% of the live production traffic to the updated Lambda function version. Which combination of steps will meet these requirements? (Choose two.)

Question

Accepted Answer

A. Publish a new version of the Lambda function that contains the updated code. Publishing a new version creates an immutable snapshot of the updated code that can be referenced by an alias for traffic shifting. C. Create an alias for the Lambda function. Configure weighted routing on the alias. Specify a 10% A Lambda alias supports weighted routing, allowing you to split traffic between two function versions - the stable version and the new one - without changing the API Gateway integration endpoint.

Answer

B. Set up a new stage in API Gateway with a new Lambda function version. Enable weighted routing API Gateway stages do not natively support weighted routing between Lambda function versions; traffic splitting for Lambda is handled at the alias level.

Answer

D. Set up a routing policy on a Network Load Balancer. Configure 10% of the traffic to go to the new Network Load Balancers operate at Layer 4 and are not designed to route traffic between Lambda function versions.

Answer

E. Set up a weighted routing policy by using Amazon Route 53. Configure 10% of the traffic to go to Route 53 weighted routing distributes traffic between different DNS endpoints (e.g., separate ALBs or IPs), not between versions of the same Lambda function.
