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 the desired properties to the device twin.

Does the solution meet the goal?

Examice · Accepted Answer

To configure the GPS location for the device entry without propagating changes to the physical device, you should use tags instead of desired properties. Desired properties in a device twin are intended to be synchronized between the cloud service and the device. Adding desired properties would result in the device receiving the updated values, which does not meet the requirement of preventing changes from being propagated to the device. Tags, on the other hand, are not visible to the device and will not be synchronized, thus satisfying the goal. Therefore, the proper solution is to use tags, making 'No' the correct answer.

=> Tags: information on the device that isn't visible to the device.
Changes should not be sent to the device, so I would go with tags and answer B 'No'

Answer should be YES ..

sballmer · Answer

I think No is the right answer, in my opinion "adding a tag to the device twin" means adding a data to the desired property, which will be transmited to the device and we must prevent changes being propagated to the device.
The solution is to add a tag to the device, not to the device twin.
