B API Gateway HTTP API with a Lambda integration
C Lambda@Edge configured on a CloudFront distribution
D Lambda Function URL configured directly on the Lambda function

B Partition key: sessionId (simple primary key)
C Partition key: userId (simple primary key)
D Partition key: randomly generated UUID, Sort key: userId

5. A developer needs to share a common set of Python libraries across multiple AWS Lambda functions to avoid bundling duplicate code in each deployment package. What is the recommended approach?
