Microsoft AZ-220 Microsoft Azure IoT Developer Exam Practice Test

You have an Azure subscription that contains an Azure loT hub named Hubl and an Azure loT Edge device named Devicel.

You need to configure Devicel to operate in extended offline mode and to support modifying the configuration of modules deployed to Device! while the device is offline.

Solution: From Microsoft Visual Studio Code, you modify the deployment manifest and you configure the address of the localhost for the container registry in the runtime settings of edgeAgent. You deploy the manifest to Device1, and then you restart the device.

You have an Azure subscription that contains an Azure loT hub named Hubl and an Azure loT Edge device named Devicel.

You need to configure Device1 to operate in extended offline mode and to support modifying the configuration of modules deployed to Device1 while the device is offline.

Solution: From Azure Cloud Shell, you run the following Azure CLI command.

ai lot edge set-nodules --device-id Device1 --hub-nane Hub1 --content deployment.json

Does this meet the goal?

You have 10 devices that connect to an Azure loT hub. Each device has a unique public IP address. The devices are not provisioned through DPS.

You discover an anomaly in messages from two devices.

You need to stop all messages from both devices without affecting the other devices.

Solution: You create a custom endpoint for the loT hub and configure a message routing query to redirect events from suspicious devices.

You discover an anomaly in messages from two devices.

You need to stop all messages from both devices without affecting the other devices.

Solution: You add IP filter rules for the devices.

Does this meet the goal?

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: Solution: You create a disabled individual enrollment by using the X.509 certificate of CA1.

Does this meet the goal?

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 loT solution that includes an Azure loT hub and a Device Provisioning Service instance.

Several enrolled devices are stolen.

You need to prevent the stolen devices from connecting to the loT solution. The solution must prevent the devices from re-enrollment and must be implemented as soon as possible.

What should you do?
