NEW QUESTION 56
You have an Azure IoT solution that includes an Azure IoT Hub named Hub1 and an Azure IoT Edge device named Edge1. Edge1 connects to Hub1.
You need to deploy a temperature module to Edge1. What should you do?
- A. Create an IoT Edge deployment manifest that specifies the temperature module and the route to
$upstream. From a Bush prompt, run the following command:
az iot hub monitor-events-device-id Edge1 -hub-name Hub1 - B. From the Azure portal, navigate to Hub1 and select IoT Edge. Select Edge1, and then select Manage Child Devices. From a Bash prompt, run the following command:
az iot edge set-modules -device-id Edge1 -hub-name Hub1 -content C:
\deploymentMan1.json - C. Create an IoT Edge deployment manifest that specifies the temperature module and the route to $upstream.
From a Bush prompt, run the following command:
az iot edge set-modules -device-id Edge1 -hub-name Hub1 -content C:\deploymentMan1.json - D. From the Azure portal, navigate to Hub1 and select IoT Edge. Select Edge1, select Device Twin, and then set the deployment manifest as a desired property. From a Bash prompt, run the following command az iot hub monitor-events-device-id Edge1 -hub-name Hub1
Answer: C
Explanation:
You deploy modules to your device by applying the deployment manifest that you configured with the module information.
Change directories into the folder where your deployment manifest is saved. If you used one of the VS Code IoT Edge templates, use the deployment.json file in the config folder of your solution directory and not the deployment.template.json file.
Use the following command to apply the configuration to an IoT Edge device:
az iot edge set-modules --device-id [device id] --hub-name [hub name] --content [file path]

You deploy modules to your device by applying the deployment manifest that you configured with the module information.
* In the Visual Studio Code explorer view, expand the Azure IoT Hub section, and then expand the Devices node.
* To confirm that the device you've chosen is an IoT Edge device, select it to expand the list of modules and verify the presence of $edgeHub and $edgeAgent. Every IoT Edge device includes these two modules.
* Select Create Deployment for Single Device.
* Navigate to the deployment manifest JSON file that you want to use, and click Select Edge Deployment Manifest.

NEW QUESTION 64
You have an Azure IoT solution that includes a standard tier Azure IoT hub and an IoT device.
The device sends one 100-KB device-to-cloud message every hour.
You need to calculate the total daily message consumption of the device. What is the total daily message consumption of the device?
- A. 2,400
- B. 0
- C. 4,800
- D. 1
Answer: D
Explanation:
Explanation
100 KB * 24 is around 2,400 bytes.
The 100 KB message is divided into 4 KB blocks, and it is billed for 25 messages. 25 times 24 is 600 Note: The maximum message size for messages sent from a device to the cloud is 256 KB. These messages are metered in 4 KB blocks for the paid tiers so for instance if the device sends a 16 KB message via the paid tiers it will be billed as 4 messages.

Box 1: Protocol translation
In the protocol translation gateway pattern, only the IoT Edge gateway has an identity with IoT Hub. The translation module receives messages from downstream devices, translates them into a supported protocol, and then the IoT Edge device sends the messages on behalf of the downstream devices.
Box 2: Advanced MessageQueuing Protocol (AMQP)
Connection multiplexing - All devices connecting to IoT Hub through an IoT Edge gateway can use the same underlying connection. This multiplexing capability requires that the IoT Edge gateway uses AMQP as its upstream protocol.

Answer:
Explanation:
Explanation:
Step 1: From Azure IoT Hub, create an IoT Edge Device
Step 2: Deploy-IoTEdge
The Deploy-IoTEdge command checks that your Windows machine is on a supported version, turns on the containers feature, and then downloads the moby runtime and the IoT Edge runtime. The command defaults to using Windows containers.
{Invoke-WebRequest -useb https://aka.ms/iotedge-win} | Invoke-Expression; ` Deploy-IoTEdge Step 3: Initialize-IoTEdge The Initialize-IoTEdge command configures the IoT Edge runtime on your machine. The command defaults to manual provisioning with Windows containers.
{Invoke-WebRequest -useb https://aka.ms/iotedge
Step 4: Enter the IoT Edge device connection string.
