Your company develops a custom module and exports the module as a Linux Dockerfile.
You need to deploy the module to an Azure IoT Edge device that runs Ubuntu Server 18.04.
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
Graphical user interface, text Description automatically generated with medium confidence

Step 1: From Microsoft Visual Studio Code,...
The Azure IoT Tools extension provides project templates for all supported IoT Edge module languages in Visual Studio Code. These templates have all the files and code that you need to deploy a working module to test IoT Edge, or give you a starting point to customize the template with your own business logic.
Step 2: Build and push the module to Azure Container Registry
Build and push your solution. Review the module code and the deployment. Then build the SampleModule container image and push it to your container registry.
Step 3: Create a deployment for the IoT Edge device.
Verify that the built container images are stored in your container registry, then deploy the modules to the device.

You have 20 devices that connect to an Azure IoT hub.
You open Azure Monitor as shown in the exhibit. (Click the Exhibit tab.)

You discover that telemetry is not being received from five IoT devices.
You need to identify the names of the devices that are not generating telemetry and visualize the data. What should you do first?

• A.Add the Number of throttling errors metric and archive the logs to an Azure storage account.
• B.Configure diagnostics for Routes and stream the logs to Azure Event Hubs.
• C.Add the Telemetry messages sent metric and archieve the logs to an Azure Storage account.
• D.Configure diagnostics for Connections and send the logs to Azure Log Analytics.

Correct Answer: D

To log device connection events and errors, turn on diagnostics for IoT Hub. We recommend turning on these logs as early as possible, because if diagnostic logs aren't enabled, when device disconnects occur, you won't have any information to troubleshoot the problem with.
Sign in to the Azure portal.
Browse to your IoT hub.
Select Diagnostics settings.
Select Turn on diagnostics.
Enable Connections logs to be collected.
For easier analysis, turn on Send to Log Analytics

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.
