Question 4

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?

APackage each Python library in its own .zip file archive. Deploy each Lambda function with its own copy of the library.

BCreate a Lambda layer with the required Python library. Use the Lambda layer in both Lambda functions.

CCombine the two Lambda functions into one Lambda function. Deploy the Lambda function as a single .zip file archive.

DDownload the Python library to an S3 bucket. Program the Lambda functions to reference the object URLs.

Question 5

A company caches session information for a web application in an Amazon DynamoDB table. The company wants an automated way to delete old items from the table.

What is the simplest way to do this?

AWrite a script that deletes old records; schedule the script as a cron job on an Amazon EC2 instance.

BAdd an attribute with the expiration time; enable the Time To Live feature based on that attribute.

CEach day, create a new table to hold session data; delete the previous day's table.

DAdd an attribute with the expiration time; name the attribute ItemExpiration.
