Microsoft AZ-220: Verify that telemetry messages from devices arrive to IoT Central.

Question

You have an Azure IoT Central solution. You need to verify that telemetry messages from devices arrive to IoT Central. What should you use?

A. the Azure IoT explorer
B. the az command in Azure CLI
C. Azure Service Bus Explorer
D. the Azure IoT Tools for VS Code extension pack

Answer

A. the Azure IoT explorer

Explanation

To verify that telemetry messages from devices arrive in Azure IoT Central, you should use option A: the Azure IoT Explorer.

Here’s a detailed explanation for why this option is the correct choice:

1. Azure IoT Central is a fully managed, cloud-based IoT platform that simplifies the deployment and management of IoT solutions. It provides a central interface for monitoring and controlling devices, as well as collecting telemetry data from those devices.
2. Azure IoT Explorer is a powerful tool specifically designed for working with Azure IoT Hub and IoT Central. It allows you to monitor and interact with devices, as well as send and receive telemetry messages.
3. By using Azure IoT Explorer, you can connect to your Azure IoT Central solution and verify that telemetry messages from devices are being received. You can subscribe to telemetry topics and observe the incoming messages in real-time.
4. Azure IoT Explorer provides a user-friendly interface with features such as device management, message routing, and device twin exploration. This makes it an ideal tool for monitoring and troubleshooting telemetry data in Azure IoT Central.

Option B, the az command in Azure CLI, is a command-line interface that can be used to interact with various Azure services. While it can be used for managing IoT resources, it is not specifically designed for verifying telemetry messages in Azure IoT Central.

Option C, Azure Service Bus Explorer, is a tool used for managing and monitoring Azure Service Bus, which is a different Azure messaging service. It is not directly related to Azure IoT Central and may not provide the necessary functionality for verifying telemetry messages.

Option D, the Azure IoT Tools for VS Code extension pack, is an extension pack for the Visual Studio Code editor that provides tools for developing and debugging IoT applications. While it can be used for development purposes, it is not specifically designed for verifying telemetry messages in Azure IoT Central.

Therefore, the correct tool to use for verifying telemetry messages from devices in Azure IoT Central is the Azure IoT Explorer (option A).
