You have an Azure IoT solution.
You need to create a digital twin model.
Which language should you use?
You have an Azure IoT hub that uses a Device Provision Service instance.
You plan to deploy 100 IoT devices.
You need to confirm the identity of the devices by using the Device Provision Service.
Which three device attestation mechanisms can you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
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 section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a Standard tier Azure IoT hub and a fleet of IoT devices.
The devices connect to the IoT hub by using either Message Queuing Telemetry Transport (MQTT) or Advanced Message Queuing Protocol (AMQP).
You need to send data to the IoT devices and each device must respond. Each device will require three minutes to process the data and respond.
Solution: You use direct methods and check the response.
Does this meet the goal?
You have an Azure IoT solution.
You need to test that the solution remains functional if IoT Hub is affected by a regional outage.
What should you do?
You deploy an Azure IoT hub.
You need to demonstrate that the IoT hub can receive messages from a device.
