Question

A company has an application that receives batches of orders from partners every day. The application uses an AWS Lambda function to process the batches. If a batch contains no orders, the Lambda function must publish to an Amazon Simple Notification Service (Amazon SNS) topic as soon as possible. Which combination of steps will meet this requirement with the LEAST implementation effort? (Choose two.)

Accepted Answer

Correct answer: A, C. The correct answer is A, C. Option A: Update the existing Lambda function's code to send an Amazon CloudWatch custom metric for the number of orders in a batch for each partner. Option C: Set up an Amazon CloudWatch alarm that will send a notification to the SNS topic when the value of the custom metric is 0. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. AWS Batch schedules and runs batch computing jobs at any scale without managing clusters. Amazon SNS is a managed pub/sub service for fan-out notifications to many subscribers.
