Question: What is the primary function of the Network Repository Function (NRF) in a 5G System?
Option 1: To manage user authentication and authorization
Option 2: To provide service discovery and maintain NF profiles
Option 3: To handle network slicing and roaming configurations
Option 4: To monitor network performance and optimize resource allocation
Explanation: The NRF plays a crucial role in the 5G System by supporting service discovery, maintaining NF profiles, and providing information about discovered NF instances. This enables efficient communication and coordination among different network functions (NFs) and service capability platforms (SCPs).
