This service makes it easy for simple devices to trigger AWS Lambda functions that execute a specific action.

• A. AWS IoT 1-Click
• B. AWS IoT Greengrass
• C. AWS IoT Events
• D. Amazon Lex

Answer: (A)

Connecting simple, button-like devices to AWS Lambda with minimal setup is what AWS IoT 1-Click is designed for. It provides pre-provisioned devices and a managed flow that triggers a Lambda function when a button is pressed, so a specific action can be executed automatically without building a full IoT system. The other services serve different purposes: AWS IoT Greengrass runs Lambda locally on edge devices for offline or low-latency processing; AWS IoT Events detects patterns in device data to trigger actions; Amazon Lex builds chatbots and is not about triggering Lambda from a physical device. So the service that makes it easy for simple devices to trigger Lambda functions is AWS IoT 1-Click.
