Question: Which reference point does the NRM-PC5 utilize for interactions related to network resource management between different VAL UEs in a 3GPP architecture?
Option 1: S1-MME (S1 Reference Point for Mobility Management Entity)
Option 2: X2 (Reference Point for Handover and Inter-eNodeB Load Balancing)
Option 3: PC5 (Proximity Services Reference Point as described in Proximity-based services, ProSe)
Option 4: N2 (Non-Access Stratum, NAS Reference Point)
Explanation: The correct answer is Option 3 because the NRM-PC5 reference point utilizes the PC5 reference point for its interactions, aligning with Proximity-based Services (ProSe) to manage network resources efficiently among nearby User Equipment.
