You have an Azure IoT hub that receives messages from an IoT device. The messages are serialized as Protobuf. You need the IoT hub to route the messages. What should you do first?

Question

Options

• AFrom the Azure portal, add desired properties to the device twin.
• BConfigure the IoT device to add application properties to the messages.
• CFrom the Azure portal, configure the IoT hub to add message enrichments.
• DConfigure the IoT device to add ASCII-encoded properties to the body of the messages.

• A

Explanation

Device twins store device-related information that: Device and back ends can use to synchronize device conditions and configuration. The solution back end can use to query and target long-running operations. Desired properties. Used along with reported properties to synchronize device configuration or conditions. The solution back end can set desired properties, and the device app can read them. The device app can also receive notifications of changes in the desired properties. Incorrect Answers: C: Message enrichments describes the ability of Azure IoT Hub to stamp messages with additional information before the messages are sent to the designated endpoint. One reason to use message enrichments is to include data that can be used to simplify downstream processing https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-device-twins
