Question: What is the primary purpose of the CAPIF_Security API in the context of 3GPP Northbound APIs?
Option 1: To manage Quality of Service (QoS) parameters for enhanced mobile broadband services.
Option 2: To facilitate the exposure of Radio Access Network (RAN) capabilities to external applications.
Option 3: To authenticate API invokers, authorize access to service APIs, and manage API invoker information and authorization revocation.
Option 4: To handle mobility management and session continuity for User Equipment (UE) across different networks.
Explanation: The correct answer is Option 3 because the CAPIF_Security API is specifically designed to handle security aspects such as authentication, authorization, and the management of API invoker information and their access rights. This aligns with the described functionality of enabling secure communication between API invaders and the CAPIF core function for accessing service APIs securely, as well as managing invoker authorizations.
