Question: What is the primary purpose of the CAPIF-5 reference point between the API management function and the CAPIF core function in a 3GPP Northbound API framework?
Option 1: To facilitate direct communication between User Equipment (UE) and the Core Network for service requests.
Option 2: To manage and monitor Radio Access Network (RAN) resources and configurations.
Option 3: To enable end-to-end encryption for all API invocations across the network.
Option 4: To manage service API, API invoker, and API provider domain function information, including onboarding, offboarding, logging, event monitoring, and policy configuration.
Explanation: The CAPIF-5 reference point is specifically defined for managing service APIs, handling API invokers (including onboarding and offboarding), and configuring policies by the API management function at the CAPIF core function, overseeing API-related operations within the 3GPP Northbound API framework.
