The IoT Central REST API is a powerful interface designed to manage devices and interact with them efficiently. One of the key functionalities of the API is to handle devices directly, including retrieving device information, executing commands, and updating device properties.

When it comes to telemetry data, while the IoT Central allows for the transmission of telemetry from devices, the actual storage and management of that telemetry data occur within the Azure IoT Central platform itself, rather than through direct API calls that perform storage actions. The API focuses on device management and interaction rather than on implementing data storage mechanisms directly on the devices.

Thus, the ability to "store telemetry data" does not align with the direct capabilities of the IoT Central REST API on devices, making this the correct answer. The other options—retrieving device lists, executing commands, and updating properties—are all actions the IoT Central API can directly perform on devices.
