Question: In the context of the Repeater Network Resources Integration Reference Point (IRP), what is a key aspect of the Network Resource Model (NRM) that enables flexible management of UTRAN resources?
Option 1: It only supports single-function managed elements.
Option 2: It utilizes a protocol-dependent modeling approach.
Option 3: It is exclusively designed for Element Managers.
Option 4: It allows for combined managed element functionality, enabling multiple specific functions within a single ManagedElement.
Explanation: The NRM's capability to accommodate more than one function within a single ManagedElement is crucial for efficiently managing complex UTRAN resources, where a network element might perform multiple distinct functions, supporting integrated management in real-world telecom scenarios.
