Demo Questions
Question 1
You create a new IoT device named device1 on iothub1. The primary key value assigned to device1 is Uihuih76hbHb.
How should you complete the device connection string? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct answer: To work with this question, an Exam Simulator is required.
Explanation:
Box 1: iothub1The Azure IoT hub is named iothub1. Box 2: azure-devices.netThe format of the device connection string looks like:HostName={YourIoTHubName}.azure-devices.net;DeviceId=MyNodeDevice;SharedAccessKey={YourSharedAccessKey} Box 1: device1Device1 has a primary key of Uihuih76hbHb. Reference:https://docs.microsoft.com/en-us/azure/iot-hub/quickstart-control-device-dotnet Box 1: iothub1
The Azure IoT hub is named iothub1.
Box 2: azure-devices.net
The format of the device connection string looks like:
HostName={YourIoTHubName}.azure-devices.net;DeviceId=MyNodeDevice;SharedAccessKey={YourSharedAccessKey}
Box 1: device1

Question 2
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 IoT solution that includes an Azure IoT hub, a Device Provisioning Service instance,and 1,000 connected IoT devices.
All the IoT devices are provisioned automatically by using one enrollment group.
You need to temporarily disable the IoT devices from the connecting to the IoT hub.
Solution: From the Device Provisioning Service, you disable the enrollment group, and you disable device entries in the identity registry of the IoT hub to which the IoT devices are provisioned.
Does the solution meet the goal?
- Yes
- No
Correct answer: A
Explanation:
You may find it necessary to deprovision devices that were previously auto-provisioned through the Device Provisioning Service. In general, deprovisioning a device involves two steps:Disenroll the device from your provisioning service, to prevent future auto-provisioning. Depending on whether you want to revoke access temporarily or permanently, you may want to either disable or delete an enrollment entry. Deregister the device from your IoT Hub, to prevent future communications and data transfer. Again, you can temporarily disable or permanently delete the device's entry in the identity registry for the IoT Hub where it was provisioned.
