Exam AWS Certified Developer Associate topic 1 question 350 discussion

B. Create a function alias. Configure the alias to split the traffic between the two versions of the Lambda function. To split traffic between the existing and new versions of a Lambda function, the developer can create a function alias and configure it to split the traffic between the two versions. A function alias is a pointer to a specific version of a Lambda function, and can be used to route traffic to the appropriate version. The developer can use the AWS Management Console or the AWS CLI to create and configure the function alias.

100% B is the correct response

B Use routing configuration on an alias to send a portion of traffic to a second function version. For example, you can reduce the risk of deploying a new version by configuring the alias to send most of the traffic to the existing version, and only a small percentage of traffic to the new version. https://docs.aws.amazon.com/lambda/latest/dg/configuration-aliases.html

B for me

Ans: D https://docs.aws.amazon.com/lambda/latest/dg/configuration-versions.html You can use versions to manage the deployment of your functions. For example, you can publish a new version of a function for beta testing without affecting users of the stable production version. Lambda creates a new version of your function each time that you publish the function. The new version is a copy of the unpublished version of the function. Note: Lambda doesn't create a new version if the code in the unpublished version is the same as the previous published version.

It is B
