Question: What is the primary purpose of the `Top` Information Object Class (IOC) as defined in the Generic Network Resource Model (NRM) Integration Reference Point (IRP)?
Option 1: To serve as a container for vendor-specific data across all Information Object Classes.
Option 2: To provide a base structure for network resource modeling specific to wireless communications.
Option 3: To be inherited from by all Information Object Classes defined in conformant standards.
Option 4: To directly manage and monitor network resources without the need for subclassing.
Explanation: The primary purpose of the `Top` IOC is to serve as a foundational class from which all other Information Object Classes, defined in conformant standards, must inherit, ensuring consistency and standardization across different implementations.
