Question: What is the primary purpose of the CAPIF-3e reference point in the context of 3GPP Northbound APIs?
Option 1: To facilitate media transfer between User Equipment (UE) and the Public Land Mobile Network (PLMN)
Option 2: To exercise access and policy-related control for service API communications initiated by the API invoker
Option 3: To manage session establishment between the Serving and Gateway Core Network nodes
Option 4: To optimize wireless resource allocation for improved Quality of Service (QoS)
Explanation: The CAPIF-3e reference point is specifically utilized for controlling access and enforcing policies related to service API communications that are initiated by the API invoker, ensuring secure and regulated interaction between the API exposing function in a 3rd party trust domain and the CAPIF core function within the PLMN trust domain.
