Question: What is a key characteristic of the Network Resource Model defined by the Generic network resources Integration Reference Point (IRP) in terms of its scope?
Option 1: The model is specifically tailored for UTRAN and CN entities.
Option 2: The model is generic, avoiding domain-specific definitions such as UTRAN or CN entities.
Option 3: The model primarily focuses on managing handovers within the same network type (e.g., UMTS to UMTS).
Option 4: The model is designed exclusively for inter-system handovers between UMTS and GSM.
Explanation: According to the requirements, the Network Resource Model must be generic, i.e., not contain any domain-specific definitions such as UTRAN or CN entities. This indicates that the model's design avoids being tailored to specific domains, ensuring broader applicability and flexibility across different network types.
