You deploy an Azure IoT hub.
You need to demonstrate that the IoT hub can receive messages from a device.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Correct Answer:

Explanation

Step 1: Register a device in IoT Hub
Before you can use your IoT devices with Azure IoT Edge, you must register them with your IoT hub. Once a device is registered, you can retrieve a connection string to set up your device for IoT Edge workloads.
Step 2: Configure the device connection string on a device client.
When you're ready to set up your device, you need the connection string that links your physical device with its identity in the IoT hub.
Step 3: Trigger a new send event from a device client.

You are writing code to provision IoT devices by using the Device Provisioning Service.
Which two details from the Overview blade of the Device Provisioning Service are required to provision a new IoT client device? To answer, select the appropriate detail in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation

Box 1: ID Scope
In the Azure portal, select the Overview blade for your Device Provisioning service and copy the ID Scope value. The ID Scope is generated by the service and guarantees uniqueness. It is immutable and used to uniquely identify the registration IDs.
Box 2: Global device endpoint
The global_prov_uri variable, which allows the IoT Hub client registration API IoTHubClient_LL_CreateFromDeviceAuth to connect with the designated Device Provisioning Service instance.
Example code:
static const char* global_prov_uri = "global.azure-devices-provisioning.net"; static const char* id_scope = "[ID Scope]"; Reference:

You need to install the Azure IoT Edge runtime on a new device that runs Windows 10 IoT Enterprise.
In which order should you perform the actions? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Correct Answer:

Explanation

Step 1: From Azure IoT hub, create an IoT Edge device
In the Azure Cloud Shell, enter the following command to create a device named myEdgeDevice in your hub.
az iot hub device-identity create --device-id myEdgeDevice --edge-enabled --hub-name {hub_name} View the connection string for your device, which links your physical device with its identity in IoT Hub.
Copy the value of the connectionString key from the JSON output and save it. This value is the device connection string. You'll use this connection string to configure the IoT Edge runtime in the step 3.
Step 2: From an elevated PowerShell prompt, run the Deploy-IoTEdge cmdlet.
Install the Azure IoT Edge runtime on your IoT Edge device.
* Run PowerShell as an administrator.
* Run the Deploy-IoTEdge command, which performs the following tasks:
- Checks that your Windows machine is on a supported version.
- Turns on the containers feature.
- Downloads the moby engine and the IoT Edge runtime.
Step 3: From an elevated PowerShell prompt, run the Initialize-IoTEdge cmdlet Step 4: Enter the IoT Edge device connection string.
Configure the IoT Edge device with a device connection string.
