Question

Drag and Drop Question You are developing an IoT solution. The solution requires bidirectional communication between a .NET application and Azure IoT Hub. You need to obtain connection information for a single test device. Which three commands should you use to develop the solution? To answer, move the appropriate commands from the list of commands to the answer area and arrange them in the correct order. NOTE: Each correct selection is worth one point. Answer:

Explanation

The correct three-command sequence is: (1) 'az extension add --name <iot-extension-name>' to install the Azure IoT CLI extension required for IoT Hub commands, (2) 'az iot hub device-identity create --hub-name <iot-hub-name> --device-id <device-id>' to register a new test device in IoT Hub, and (3) 'az iot hub device-identity show-connection-string --hub-name <iot-hub-name> --device-id <device-id>' to retrieve the device connection string needed for bidirectional communication in the .NET application. This sequence follows the logical flow of: install prerequisites → create the device identity → retrieve connection credentials.
