AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 179

Question

A solutions architect is designing a solution to process events. The solution must have the ability to scale in and out based on the number of events that the solution receives. If a processing error occurs, the event must move into a separate queue for review. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Send event details to an Amazon Simple Notification Service (Amazon SNS) topic. Configure an AWS Lambda function as a subscriber to the SNS topic to process the events. Add an on-failure destination to the function. S... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. Amazon SNS is a managed pub/sub service for fan-out notifications to many subscribers.
