The solution must maximize the scalability of the Lambda function and must prevent successfully processed SQS messages from being processed multiple times.

Which solution will meet these requirements?

Options:

A.

Set the batch window to 1 second in the Lambda function ' s event source mapping.

B.

Set the batch size to 1 in the Lambda function ' s event source mapping.

C.

Set a value of ReportBatchItemFailures in the FunctionResponseTypes list in the Lambda function ' s event source mapping.

D.

Set the reserved concurrency to 1 in the Lambda function ' s concurrency and recursion detection settings.

Question 54

A large enterprise is deploying a web application on AWS. The application runs on Amazon EC2 instances behind an Application Load Balancer.
