Question: In a 5G network, when using the SMF (Session Management Function), which of the following services does NOT require mapping between HTTP responses and 5GSM cause values for communication with UEs?
Option 1: Nsmf_PDUSession service over N11 interface
Option 2: Nsmf_EventExposure service as specified in relevant standards
Option 3: Custom Application Service over N19 interface
Option 4: Nsmf_PDUSession service over N16 interface
Explanation: No mapping is required for the Nsmf_PDUSession service over N11 since the SMF includes the 5GSM cause in messages sent, indicating that necessary cause values are already integrated into the messaging.
