Câu 54: AWS Certified Developer - Associate DVA-C02(New)

A developer is designing a serverless application with two AWS Lambda functions to process photos. One Lambda function stores objects in an Amazon S3 bucket and stores the associated metadata in an Amazon DynamoDB table. The other Lambda function fetches the objects from the S3 bucket by using the metadata from the DynamoDB table. Both Lambda functions use the same Python library to perform complex computations and are approaching the quota for the maximum size of zipped deployment packages. What should the developer do to reduce the size of the Lambda deployment packages with the LEAST operational overhead?

1. A. Package each Python library in its own .zip file archive. Deploy each Lambda function with its own copy of the library.
2. B. Create a Lambda layer with the required Python library. Use the Lambda layer in both Lambda functions. — đáp án hiện tại
