Question 26
You have an Azure IoT solution that includes a basic tier Azure IoT hub named Hub1 and a Raspberry Pi device named Device1. Device1 connects to Hub1.
You back up Device1 and restore the backup to a new Raspberry Pi device.
When you start the new Raspberry Pi device, you receive the following error message in the diagnostic logs of Hub1: "409002 LinkCreationConflict." You need to ensure that Device1 and the new Raspberry Pi device can run simultaneously without error.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
