Exam AZ-220 topic 2 question 13 discussion

Actual exam question from Microsoft's AZ-220
Question #: 13
Topic #: 2
[All AZ-220 Questions]

You have 1,000 IoT devices that connect to an Azure IoT hub.
Each device has a property tag named city that is used to store the location of the device.
You need to update the properties on all the devices located at an office in the city of Seattle as quickly as possible. Any new devices in the Seattle office that are added to the IoT hub must receive the updated properties also.
What should you do?

  • A. From Automatic Device Management, create an IoT device configuration.
  • B. From the IoT hub, generate a query for the target devices.
  • C. Create a scheduled job by using the IoT Hub service SDKs.
  • D. Deploy an Azure IoT Edge transparent gateway to the Seattle office and deploy an Azure Stream Analytics edge job.

Suggested Answer: A 🗳️
Automatic device management in Azure IoT Hub automates many of the repetitive and complex tasks of managing large device fleets. With automatic device management, you can target a set of devices based on their properties, define a desired configuration, and then let IoT Hub update the devices when they come into scope. This update is done using an automatic device configuration or automatic module configuration, which lets you summarize completion and compliance, handle merging and conflicts, and roll out configurations in a phased approach.

not sure why C can’t be true (too). From https://docs.microsoft.com/en-us/azure/iot-develop/about-iot-sdks: IoT Hub The IoT Hub service SDKs allow you to build applications that easily interact with your IoT Hub to manage devices and security. You can use these SDKs to send cloud-to-device messages, invoke direct methods on your devices, update device properties, and more.

Agreed, there is more then one way to skin a cat) And SDK can do it also, and I would say SDK works under the hood of Automatic device management. But MS always ask how to do something easiest and simpliest way, so A. btw SDK is the only way to do it on basic tier because Automatic device management use twins
