You have 10 IoT devices that connect to an Azure IoT hub named Hub1.
From Azure Cloud Shell, you run az iot hub monitor-events --hub-name Hub1 and receive the following error message: "az iot hub: 'monitor-events' is not in the 'az iot hub' command group. See 'az iot hub
--help'."
You need to ensure that you can run the command successfully. What should you run first?

• A.az iot hub monitor-feedback --hub-name Hub1
• B.az iot hub generate-sas-token --hub-name Hub1
• C.az iot hub configuration list --hub-name Hub1
• D.az extension add -name azure-cli-iot-ext

You have an Azure IoT solution that includes an Azure IoT Hub named Hub1 and an Azure IoT Edge device named Edge1. Edge1 connects to Hub1.
You need to deploy a temperature module to Edge1. What should you do?

• A.From the Azure portal, navigate to Hub1 and select IoT Edge. Select Edge1, and then select Manage Child Devices. From a Bash prompt, run the following command:
  az iot edge set-modules -device-id Edge1 -hub-name Hub1 -content C:
  \deploymentMan1.json
• B.Create an IoT Edge deployment manifest that specifies the temperature module and the route to
  $upstream. From a Bush prompt, run the following command:
  az iot hub monitor-events-device-id Edge1 -hub-name Hub1
• C.From the Azure portal, navigate to Hub1 and select IoT Edge. Select Edge1, select Device Twin, and then set the deployment manifest as a desired property. From a Bash prompt, run the following command az iot hub monitor-events-device-id Edge1 -hub-name Hub1
• D.Create an IoT Edge deployment manifest that specifies the temperature module and the route to
  $upstream. From a Bush prompt, run the following command:
  az iot edge set-modules -device-id Edge1 -hub-name Hub1 -content C:
  \deploymentMan1.json
