Provision and manage devices

Question

You have an Azure IoT solution that includes multiple Azure IoT hubs in different geographic locations and a single Device Provision Service instance. You need to configure device enrollment to assign devices to the appropriate IoT hub based on the following requirements: - The registration ID of the device - The geographic location of the device - The load between the IoT hubs in the same geographic location must be balanced. What should you use to assign the devices to the IoT hubs?

Options

  • AStatic configuration (via enrollment list only)
  • BLowest latency
  • CEvenly weighted distribution
  • DCustom (Use Azure Function)

Explanation

Set the Device Provisioning Service allocation policy The allocation policy is a Device Provisioning Service setting that determines how devices are assigned to an IoT hub. There are three supported allocation policies: Lowest latency: Devices are provisioned to an IoT hub based on the hub with the lowest latency Evenly weighted distribution (default): Linked IoT hubs are equally likely to have devices provisioned to them. This is the default setting. If you are provisioning devices to only one IoT hub, you can keep this setting. Static configuration via the enrollment list: Specification of the desired IoT hub in the enrollment list takes priority over the Device Provisioning Service-level allocation policy. https://docs.microsoft.com/en-us/azure/iot-dps/tutorial-provision-multiple-hubs
