What type of device template is used to create custom capabilities in Azure IoT Central?

The correct choice is IoT device template. In Azure IoT Central, an IoT device template is essential for defining the capabilities, properties, and telemetry of the devices you wish to connect. This template serves as a blueprint that outlines how an IoT device operates within the Azure IoT Central environment, including the data it can send and receive, the commands it can execute, and the properties that can be monitored or controlled.

Creating custom capabilities allows developers to tailor the solution specific to their device’s functionality, leading to better integration and management within the IoT ecosystem. By utilizing the device template, developers can ensure that the application reflects the specific needs and behaviors of the devices they are working with, facilitating precise monitoring and control.

In contrast, Azure IoT Edge refers to cloud workload distributed to devices, primarily for running cloud analytics and intelligence at the edge. IoT Plug and Play is a feature designed to simplify device integration and interoperability with Azure IoT services by providing a standardized interface. Virtual devices are typically used for simulation purposes or testing, rather than creating custom device capabilities. Each of these options serves a different purpose in Azure IoT but does not specifically focus on creating the device templates necessary for custom capabilities in IoT Central.
