Question: What is the primary purpose of the Nsmf_TrafficCorrelation service in the 5G System (5GS)?
Option 1: To enable SMF to request UE location from the AMF.
Option 2: To allow NEF to retrieve UE subscription data from the UDR.
Option 3: To facilitate communication between AF and PCF for policy control.
Option 4: To notify NF Consumer (NEF) about 5GC determined information for a set of UEs identified by Traffic Correlation ID.
Explanation: The Nsmf_TrafficCorrelation service is used to inform the NEF about specific 5G Core Network (5GC) information related to a group of User Equipments (UEs), which are identified using a Traffic Correlation ID. This allows the NEF to store this data in the Unified Data Repository (UDR) alongside AF requests, ultimately influencing traffic routing decisions.
