Microsoft AZ-220 Microsoft Azure IoT Developer Exam Practice Test

You are prototyping an loT edge solution.

You are creating a deployment manifest for an loT edge device that will connect to an Azure loT hub. Which two modules should you include in the manifest? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

HA.

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 loT Hub deployment.

You plan to deploy 1,000 loT devices that will have 1 MB of RAM. The devices will be deployed behind firewalls that block port 443. You need to configure the communication protocol for the devices. The solution must ensure that each device uses unique credentials. Which protocol should you use?

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 loT solution that contains an Azure loT Edge device named Edgel.

Edge! fails to start.

You connect to Edgel and identify the following:

* The loT Edge agent is running.

* The loT Edge agent continually reports the following error "Empty dconfig file."

* No modules have started.

You need to ensure that Edge1 starts successfully. What should you do?

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.

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: You delete the device entry from the device registry of Hub1. Does this meet the goal?
