A company has designed a serverless application that uses Amazon Simple Queue Service (Amazon SQS) nd an AWS Lambda function. The application receives data in an SQS queue on the last day of every onth. The function successfully processes all the data in the queue within 1 day.
A detailed AWS bill shows a large number of SQS API requests throughout the month, even though the ueue receives data only on the last day of the month.
What is the root cause of the extra API requests?
A. Lambda is using long polling to check for messages in the SQS queue.
B. The SQS queue is sending ping messages to Lambda.
C. The function is not automatically deleting the messages from the SQS queue.
D. Visibility timeout is not set to 0 to remove the extra API requests.
