Question: What is a key characteristic of the Interface Specification (IS) defined by the Configuration Management Basic Integration Reference Point (IRP), in relation to Network Resource Models (NRMs)?
Option 1: The IS requires a specific set of Management Objects Classes (MOCs) for all NRMs.
Option 2: The IS is designed to be as independent as possible from specific MOC definitions and attributes in the referenced NRMs.
Option 3: The IS only supports access to NRMs defined by a single, unified 3GPP specification.
Option 4: The IS mandates a particular NRM for all network management operations.
Explanation: This correct answer reflects the requirement that the Interface Specification (IS) should be as far as possible independent of any specific definitions of Management Objects Classes (MOCs), attributes, etc., in the Network Resource Models (NRMs) it interacts with. This independence allows for greater flexibility and compatibility across different NRMs, enhancing its utility in diverse telecom management scenarios.
