Exam AZ-220 topic 3 question 3 discussion

answer is BD B: "Azure IoT Edge relies on an OCI-compatible container runtime. For production scenarios, we recommended that you use the Moby engine. The Moby engine is the only container engine officially supported with Azure IoT Edge." https://docs.microsoft.com/en-us/azure/iot-edge/how-to-install-iot-edge?view=iotedge-2018-06#install-a-container-engine D: "The IoT Edge security daemon provides and maintains security standards on the IoT Edge device. The daemon starts on every boot and bootstraps the device by starting the rest of the IoT Edge runtime." https://docs.microsoft.com/en-us/azure/iot-edge/how-to-install-iot-edge?view=iotedge-2018-06#install-iot-edge A is wrong because it refers to an update

So what is the right answer???

I think it should be A,D? https://docs.microsoft.com/en-us/azure/iot-edge/how-to-provision-single-device-linux-symmetric?view=iotedge-2020-11&tabs=azure-portal%2Cubuntu says "install container engine" and "Install the IoT Edge runtime"

Agree with BD

Agree with BD

B&D is correct as we see link https://docs.microsoft.com/en-us/azure/iot-edge/how-to-provision-single-device-linux-symmetric?view=iotedge-2020-11&tabs=azure-cli

Answer is CD You need to first deploy the IoT Edge runtime and then install it (initialize). How can you update the runtime without deploying it. The security daemon automatically gets added as a part of IoT Edge runtime.
