A development team needs to redirect a portion of live traffic to a new version of an AWS Lambda function to test its behavior under load while maintaining the stability of their production environment. Which feature of AWS Lambda should the team use to achieve this goal without affecting all users at once?
Use an environment variable to redirect a portion of traffic to a different Lambda function.
Create an alias for the Lambda function and configure weighted traffic distribution between the production version and the new version.
Use the $LATEST version of the Lambda function to gradually shift traffic to the new version.
Reference the new version of the Lambda function using its Amazon Resource Name (ARN) with a specific ratio in the production environment.
