1. You develop a custom Azure IoT Edge module named temperature-module.

You publish temperature-module to a private container registry named

You need to build a deployment manifest for the IoT Edge device that will run temperature-module.

Which three container images should you define in the manifest? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.


You have an Azure IoT Edge device named Edge1.

You need to configure the module container to link the module storage to the host storage.

How should you configure the deployment manifest? To answer, drag the appropriate keys to the correct targets. Each key may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

3. You create an Azure IoT hub by running the following command.

az iot hub create --resource-group MyResourceGroup --name MyIotHub --sku B1 -- location westus --partition-count 4

What does MylotHub support?

4. You have an Azure IoT solution that includes an Azure IoT hub.

You plan to deploy 10,000 IoT devices.

You need to validate the performance of the IoT solution while 10,000 concurrently connected devices stream telemetry. The solution must minimize effort.

What should you deploy?

5. 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?

6. You have 1,000 devices that connect to a standard tier Azure IoT hub.

All the devices are commissioned and send telemetry events to the built-in IoT Hub endpoint. You configure message enrichment on the events endpoint and set the enrichment value to $twin.tags.ipV4.

When you inspect messages on the events endpoint, you discover that all the messages are stamped with a string of "$twin.tags.ipV4".

What are two possible causes of the issue? Each Answer presents a complete solution. NOTE: Each correct selection is worth one point.

7. You have an Azure loT hub.

You need to configure an Azure function that will process loT Hub messages when the messages arrive at the loT hub. The solution must NOT require additional services or solutions deployed.

Which type of trigger should you use?


You have an Azure subscription that contains an Azure loT hub named Hub1 and the IoT devices shown in the following table.

You have the automatic device configure rations shown in the following table.

For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

9. Topic 3, Fabrikam New

Case study

General overview

Fabrikam, Inc. is an international food company that has a main office in London and 250 sites worldwide.

FabRIkam uses a prototype hydroponics loT management system that tracks temperatures and PH levels and adjusts conditions automatically.


The prototype environment is deployed to the main office.

IoT Hub

The management system uses a free tier Azure loT hub.


The prototype contains the devices shown in the following table.

Each device will use the following:

• A common set of Azure loT Edge modules

• A unique module for each type of sensor or controller

Each device has a device twin. Each device twin contains a tag that identifies the device type. For example, the device twin of Child4 contains a tag of ph. Each device sends 1.440 4-KB messages to the loT hub per day.

Pilot deployment

A pilot of the hydroponics loT management system will be deployed initially to 50 of the company's worldwide sites.

Device Requirements

Fabrikam identifies the following device requirements:

• Cloud-to-device commands will be sent to each primary control device.

• All module communication from the child devices must be routed to the loT hub.

• The parameters of each device type must be configured in the loT Edge container configuration file.

• Device modules must be deployed to all the devices automatically, and then updated automatically. The solution must support targeted deployments by using device twin tags.

Networking Requirements

Fabrikam identifies the following networking requirements:

• Child devices will NOT have internet access.

• The primary control device in each site will have internet access.

• Child devices will communicate with their local primary control device by using the AMQP protocol.

Monitoring Requirements

Fabrikam identifies the following monitoring requirements:

• The number of device-to-cloud telemetry messages sent to the loT hub by the primary control devices must be tracked.

• An email notification must be sent if a message is NOT received from Child4 every 10 minutes.

Technical Requirements

Fabrikam identifies the following technical requirements:

• The solution must support cloud-to-device commands.

• Administrative effort must be minimized whenever possible.

• Hardware and software costs must be minimized whenever possible.

• Access to the loT hub must be restricted to devices that connect from the company's sites.

You need to develop a messaging app that meets the technical requirements.

Which shared access policy should you use?

10. 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 query to the following.

Does this meet the goal?
