Answer: Create a version from the current production Lambda function, update the API Gateway to point to this version, publish the optimized code, set a canary release on the production stage with traffic percentage, and use the $LATEST version for the endpoint, publishing to the canary.
Option A is the correct answer because it involves defining a function version for the existing production Lambda function, updating the API Gateway to reference this version, and then publishing the optimized code. A canary release is set up on the production API Gateway stage to direct a specified percentage of traffic to the canary release, allowing the changes to be tested in production without changing the API Gateway URL. This step-by-step process ensures controlled traffic distribution and thorough testing of the optimized code.
