You have an Azure IoT solution that includes an Azure IoT hub and 100 Azure IoT Edge devices.

You plan to deploy the IoT Edge devices to external networks. The firewalls of the external networks only allow traffic on port 80 and port 443.

You need to ensure that the devices can connect to the IoT hub. The solution must minimize costs.

You have an Azure loT solution that includes an Azure loT hub named Hub1.

You plan to provision an loT device named Device! that will run Azure RTOS and the Azure loT middleware for Azure RTOS. Device1 will be deployed to a remote network that contains a firewall named FW1.

You need to ensure that FW1 will allow Device1 to communicate with Hub1.

Which port should you open on FW1?

You have an Azure subscription that contains the resources shown in the following table.

You create a group enrollment in DPS1 and enroll 100 loT devices. Each device is issued a leaf certificate from CAT. You need to deprovision a single loT device from the group enrollment. The solution must not affect the other devices.

Solution: You create a disabled individual enrollment by using the X.509 certificate of the device.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have a Standard tier Azure IoT hub and a fleet of IoT devices.

The devices connect to the IoT hub by using either Message Queuing Telemetry Transport (MQTT) or Advanced Message Queuing Protocol (AMQP).

You need to send data to the IoT devices and each device must respond. Each device will require three minutes to process the data and respond.

Solution: You use cloud-to-device messages and watch the cloud-to-device feedback endpoint for successful acknowledgement.

Correct Answer:

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.

When prompted, provide the device connection string that you retrieved in step 1. The device connection string associates the physical device with a device ID in IoT Hub.

You have an Azure subscription that contains an Azure IoT hub, 500 IoT devices, and an Azure Time Series Insights Gen2 environment named Environment1.

You need to add calculated values to the Time Series Model.
