Question

A developer is creating an AWS Lambda function that is invoked by messages to an Amazon Simple Notification Service (Amazon SNS) topic. The messages represent customer data updates from a customer relationship management (CRM) system The developer wants the Lambda function to process only the messages that pertain to email address changes. Additional subscribers to the SNS topic will process any other messages. Which solution will meet these requirements in the LEAST development effort?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Use an SNS filter policy on the Lambda function subscription to allow only messages that are related to email address changes to invoke the Lambda function. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SNS is a managed pub/sub service for fan-out notifications to many subscribers. This option needs the least custom development effort.
