Question: What is the primary purpose of including both MCC (Mobile Country Code) and MNC (Mobile Network Code) in a NF Service Set Identifier for a PLMN (Public Land Mobile Network)?
Option 1: To provide redundancy in case one of the codes is corrupted during transmission.
Option 2: To uniquely identify the network operator and country, ensuring global uniqueness of the NF Service Set.
Option 3: To differentiate between various NF instances within the same network.
Option 4: To indicate the type of services offered by the NF Service Set.
Explanation: Including both MCC and MNC in a NF Service Set Identifier for a PLMN is crucial for uniquely identifying the network operator (MNC) and the country (MCC) where the network operates. This combination ensures that each NF Service Set can be globally distinguished, which is vital for distribution, redundancy, and scalability across different networks and geographical locations. While NF Instance ID differentiates between instances within a network (Option 3), and service type isn't directly indicated by MCC/MNC (Option 4), the primary purpose of MCC/MNC in this context is to ensure global uniqueness tied to a specific operator in a country, making Option 2 the correct answer.
