You need to deploy a third-party machine learning model to IoT Edge devices for local inferencing. The model is packaged as a Docker container. Which component of IoT Edge is responsible for managing the lifecycle of this container on the device?

✓ Correct Answer & ExplanationAzure IoT Edge

Correct Answer

IoT Edge Agent (edgeAgent) module

Why This Answer Is Correct

The IoT Edge Agent (edgeAgent) is the management plane of IoT Edge. It reads the deployment manifest from IoT Hub, pulls container images from the registry, and manages the lifecycle (start, stop, restart) of all modules including custom containers. edgeHub handles message routing between modules and upstream.

More Azure IoT Edge Practice Questions

You have an Azure IoT Edge device deployed at a factory. A custom module processes sensor data and should forward only anomaly alerts to IoT Hub to minimize bandwidth. Normal readings should be discarded at the edge. How do you configure this routing?

An IoT Edge device in a remote oil field has intermittent internet connectivity. You need the device to continue collecting and processing sensor data during outages and sync to the cloud when connectivity is restored. Which IoT Edge capability enables this?

You need legacy devices without native IoT SDK support to connect to IoT Hub through an IoT Edge device. Each legacy device should appear as a separate device identity in IoT Hub. Which IoT Edge gateway pattern should you implement?

You are deploying an IoT Edge solution to 500 devices in a factory. You need to update the deployment manifest for all devices simultaneously whenever a new module version is released. Which approach scales for 500 devices without manual per-device updates?

You need to deploy an IoT Edge custom module that requires access to a hardware device (e.g., /dev/ttyUSB0 for serial communication) on the host gateway. How should you configure this module in the deployment manifest?
