Topic #: 22
You have an Azure IoT solution that includes an Azure IoT hub, 100 Azure IoT Edge devices, and 500 leaf devices.
You need to perform a key rotation across the devices.
Which three types of entities should you update? Each Answer presents part of the solution.
NOTE: Each correct selection is worth one point.
To get authorization to connect to IoT Hub, devices and services must send security tokens signed with either a shared access or symmetric key. These keys are stored with a device identity in the identity registry.
An IoT Hub identity registry can be accessed like a dictionary, by using the deviceId or moduleId as the key. Reference:
