What type of devices can you add to an IoT Central application?

The correct choice encompasses both real and simulated devices, highlighting the flexibility of Azure IoT Central in accommodating various device types. In an IoT Central application, users have the ability to connect actual physical devices that are deployed in real-world environments for collecting and transmitting data. This allows for the monitoring and management of devices in real-time.

Additionally, Azure IoT Central supports simulated devices, which are virtual representations of physical devices. These simulated devices enable developers to test and validate various aspects of their applications without needing to deploy physical hardware. This capacity is particularly useful for prototyping and testing scenarios, allowing users to experiment with different configurations and settings before moving to a production environment.

A combination of both real and simulated devices provides a comprehensive framework that supports the development and management of IoT applications, catering to different use cases in the IoT lifecycle. This dual capability enhances development efficiency and reduces timelines by allowing for simultaneous work on both device types.
