During the POV phase, telemetry from IoT Hub stops flowing to the hot path. The cold path continues to work.
What should you do to restore the hot path?

• A.Run the Test all routes action.
• B.Create an explicit route for the hot path.
• C.Disable the fallback route.
• D.Modify cold-route to send only some telemetry data to the cold path.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this question, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have devices that connect to an Azure IoT hub. Each device has a fixed GPS location that includes latitude and longitude.
You discover that a device entry in the identity registry of the IoT hub is missing the GPS location.
You need to configure the GPS location for the device entry. The solution must prevent the changes from being propagated to the physical device.
Solution: You add the desired properties to the device twin. Does the solution meet the goal?

• A.No
• B.Yes

You create an Azure IoT hub by running the following command.
az iot hub create --resource-group MyResourceGroup --name MyIotHub --sku B1 -- location westus --partition-count 4 What does MylotHub support?

• A.cloud-to-device messaging
• B.Device Provisioning Service
• C.Azure IoT Edge
• D.device twins

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?

• A.Configure the upstream protocol of the devices to use MQTT over TCP.
• B.Integrate cellular communication hardware onto the devices and avoid the use of the external networks.
• C.Connect the external networks to the loT solution by using ExpressRoute.
• D.Configure the upstream protocol of the devices to use AMQP over WebSocket.
