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 devices that connect to an Azure IoT hub. Each device has a fixed GPS location that includes latitude and longitude.

You discover that a device entry in the identity registry of the IoT hub is missing the GPS location.

You need to configure the GPS location for the device entry. The solution must prevent the changes from being propagated to the physical device.

Solution: You add tags to the device twin.

Does the solution meet the goal?

Show Answer
Correct Answer: A

To configure the GPS location for the device entry without propagating changes to the physical device, using tags in the device twin is the appropriate solution. Tags are a section of the JSON document that the solution back end can read from and write to, and they are not visible to device apps. This ensures that any updates made to the GPS location will not be sent to or affect the physical device, thereby meeting the goal of the solution.

Yeah, Answer is No because solution is: Tags. A section of the JSON document that the solution back end can read from and write to. Tags are not visible to device apps. https://docs.microsoft.com/de-de/azure/iot-hub/iot-hub-devguide-device-twins

WRONG! you are correct, the answer is tags. A desired property: is WRITTEN by a back-end application and READ ONLY by a device. A reported property is WRITTEN by a device and READ ONLY by a back-end application. A tag is set by a back-end application and is NEVER sent to a device. https://docs.microsoft.com/en-us/azure/iot-hub/tutorial-device-twins (some clown has copied the same answers from 1 question to all the questions of this sim)
