AWS Certified Developer Associate Practice Test 2

Correct answer - "Use AWS Lambda aliases" : AWS Lambda also supports creating aliases for each of your Lambda function versions. Conceptually, an AWS Lambda alias is a pointer to a specific Lambda function version. It is also a resource similar to a Lambda function, and each alias has a unique ARN. Each alias maintains an ARN for the function version to which it points.

"Disable AWS Lambda versioning" - Although possible, aliases are a great way to shift traffic when new versions are available

"Use environment variables" - Environment variables enable you to dynamically pass settings to your function code

"Enable X-Ray integration" - You can use AWS X-Ray to trace your AWS Lambda functions
