Question: What is the primary function of the Network Slice Admission Control Function (NSACF) in a 5G Core Network (5GC)?
Option 1: To manage Quality of Service (QoS) for all User Equipment (UE) across all network slices.
Option 2: To allocate IP addresses to UEs connecting to the network.
Option 3: To monitor and control the number of registered UEs and PDU Sessions per network slice, based on predefined maximum allowances.
Option 4: To handle handover decisions between different Radio Access Technologies (RATs).
Explanation: The NSACF's primary role is to ensure that the number of User Equipment (UE) registrations and Protocol Data Unit (PDU) sessions for each network slice do not exceed configured maximum limits, maintaining service quality and preventing overload within specific slices.
