Correct Answer: D. Create an Amazon Simple Queue Service (Amazon SQS) queue Send the requests to the queue.Configure the queue as an event source for Lambda

Explanation

解析:An event source mapping is a Lambda resource that reads from an event source and invokes a Lambda function. You can use event source mappings to process items from a stream or queue in services that don't invoke Lambda functions directly.https://docs.aws.amazon.com/lambda/latest/dg/invocation-eventsourcemapping.html
