Implement IoT Edge
Question
You have an Azure IoT solution that includes an Azure IoT hub and 100 Azure IoT Edge devices. You plan to deploy the IoT Edge devices to external networks. The firewalls of the external networks only allow traffic on port 80 and port 443. You need to ensure that the devices can connect to the IoT hub. The solution must minimize costs. What should you do?
Options
- AConfigure the upstream protocol of the devices to use MQTT over TCP.
- BConfigure the upstream protocol of the devices to use AMQP over WebSocket.
- CConnect the external networks to the IoT solution by using ExpressRoute.
- DIntegrate cellular communication hardware onto the devices and avoid the use of the external networks.
