Question: What is the primary purpose of the Nnef_ServiceParameter_Update operation in the 5G System (5GS)?
Option 1: To retrieve service-specific parameters from the UDR via the NEF.
Option 2: To update service-specific parameters in the UDR via the NEF.
Option 3: To delete service-specific parameters from the UDR via the NEF.
Option 4: To create new service-specific parameters in the UDR via the NEF.
Explanation: The Nnef_ServiceParameter_Update operation is used by the consumer to update service-specific parameters in the User Data Repository (UDR) via the Network Exposure Function (NEF). This allows for dynamic changes to be made to the service parameters, which can impact how services are delivered to users.
