Question: In a 3GPP Northbound API context, what is the primary benefit of utilizing the Common API Framework (CAPIF) in a nested API invocation scenario, such as when a Location Management Server invokes NEF API to retrieve UE (User Equipment) location information from 5GC?
Option 1: Enhanced Security through Increased Authorization Checks
Option 2: Improved Network Latency for UE Location Retrieval
Option 3: Simplified API Invocation Procedures for External Servers
Option 4: Reduced Authorization Information Inquiries Across Nested API Calls
Explanation: The correct answer, "Reduced Authorization Information Inquiries Across Nested API Calls", highlights the key advantage of using CAPIF in nested API invocations. By minimizing repeated authorization checks, the framework optimizes the process, making it more efficient for scenarios like the described location information retrieval from 5GC, where one API call triggers another within the same provider domain. This directly aligns with the mentioned capability of CAPIF to reduce authorization information inquiries in such nested scenarios.
