Question: What is the purpose of using network slicing mechanisms to provide access to a Non-Public Network (NPN) as a network slice of a Public Land Mobile Network (PLMN)?
Option 1: To allow the NPN service provider to manage the PLMN's network resources.
Option 2: To enable the UE to access both PLMN services and PNI-NPN services using different S-NSSAI/DNN for different services.
Option 3: To restrict the availability of the NPN S-NSSAI to a specific geographic area agreed upon by the PLMN and NPN service provider.
Option 4: To prevent unauthorized access to the NPN by using Unified Access Control with operator-defined access categories.
Explanation: The correct answer is Option 2 because network slicing mechanisms allow the UE to access both PLMN services and PNI-NPN services using different S-NSSAI/DNN for different services, as mentioned in the note. This enables the UE to use different network slices for different services, providing a more flexible and efficient way of accessing multiple networks.
