Question: Which entity supports the functions related to location management for the Nnef interface in a 5G System (5GS) architecture?
Option 1: Location Management Server
Option 2: UAS Application Server
Option 3: User Equipment (UE)
Option 4: Network Exposure Function (NEF) itself, without external support
Explanation: According to the specified interactions for a 5GS architecture, functions related to location management of the Nnef interface are supported by a dedicated Location Management Server, distinguishing it from the UAS Application Server which supports other Nnef interface functions. This highlights the modular and specialized nature of 5G system architectures.
