Question: What is the primary outcome of registering API provider domain functions on the Common API Framework (CAPIF)?
Option 1: To enable direct communication between User Equipment (UE) and the API provider.
Option 2: To restrict access to sensitive network information for all API users.
Option 3: To facilitate load balancing across multiple API provider domains.
Option 4: To authorize the API provider domain functions as legitimate users of CAPIF functionalities.
Explanation: Registering API provider domain functions on the CAPIF primarily serves to establish these functions as authorized entities, granting them approved access to utilize the framework's functionalities. This is crucial for maintaining security and ensuring that only vetted components interact with the CAPIF, thereby protecting the integrity of the telecom network's northbound interfaces.
