Microsoft Azure IoT Developer - AZ-220 Exam Practice Test

You have an loT device that has the following configurations:
* Hardware: Raspberry Pi
* Operating system: Raspberry Pi OS
You need to deploy Azure loT Edge to the device.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

You have an Azure subscription named Sub1 that contains five Azure loT hubs in the basic tier.
You assign an Azure policy named Policy! to Subl. Policy 1 ensures that when an loT hub is deployed, a pnvate endpoint is deployed for the loT hub.
You need to ensure that Policyl is applied to the existing loT hubs. The solution must minimize administrative effort.
What should you do?

You have an Azure IoT Central application.
You need to connect an IoT device to the application.
Which two settings do you require in IoT Central to configure the device? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

You have an Azure loT Central application. One thousand devices are registered to the application.
You need to modify a property on all the devices. The solution must minimize administrative effort.
What should you create?

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 an Azure Stream Analytics job that receives input from an Azure IoT hub and sends the outputs to Azure Blob storage. The job has compatibility level 1.1 and six streaming units.
You have the following query for the job.

You plan to increase the streaming unit count to 12.
You need to optimize the job to take advantage of the additional streaming units and increase the throughput.
Solution: You change the compatibility level of the job to 1.2.
Does this meet the goal?

You have 10 IoT devices that connect to an Azure IoT hub named Hub1.
From Azure Cloud Shell, you run az iot hub monitor-events --hub-name Hub1 and receive the following error message: "az iot hub: 'monitor-events' is not in the 'az iot hub' command group. See 'az iot hub
--help'."
You need to ensure that you can run the command successfully. What should you run first?

You plan to deploy an Azure IoT hub.
The IoT hub must support the following:
Three Azure IoT Edge devices 2,500 IoT devices
Each IoT device will spend a 6 KB message every five seconds.
You need to size the IoT hub to support the devices. The solution must minimize costs. What should you choose?

You have an loT solution that includes an Azure IoT hub named Hub1 and 20 loT devices. Hub1 sends cloud-to-device messages to the 10T devices.
You need to track the number of messages that are resubmitted for delivery to an IoT device. Which metric should you monitor?

You have an Azure solution that contains an Azure loT Edge deployment.
You are configuring an Azure Stream Analytics Edge job as shown in the following exhibit.
How should you complete the query? To answer select the appropriate options m the answer area.
NOTE: Each correct selection is worth one point.

You have 100 devices that connect to an Azure IoT hub named Hub1. The devices connect by using a symmetric key.
You deploy an IoT hub named Hub2.
You need to migrate 10 devices from Hub1 to Hub2. The solution must ensure that the devices retain the existing symmetric key.
What should you do?

You have an Azure IoT hub that uses a Device Provisioning Service instance to automate the deployment of Azure IoT Edge devices.
The IoT Edge devices have a Trusted Platform Module (TPM) 2.0 chip.
From the Azure portal, you plan to add an individual enrollment to the Device Provisioning Service that will use the TPM of the IoT Edge devices as the attestation mechanism.
Which detail should you obtain before you can create the enrollment.

You have an Azure loT hub and an Azure virtual network.
You configure a private endpoint for the IoT hub.
You need to ensure that the loT hub can send data to downstream services What should you create first?
