Question: What is the primary difference between an SNPN and a PLMN in terms of network functions?
Option 1: An SNPN relies on network functions provided by a PLMN, while a PLMN does not rely on any external network functions.
Option 2: An SNPN does not rely on network functions provided by a PLMN, whereas a PLMN provides network functions to other networks.
Option 3: An SNPN and a PLMN are identical in terms of network functions, with no differences between them.
Option 4: An SNPN is a subset of a PLMN, providing only a limited set of network functions.
Explanation: According to the text, an SNPN (Stand-Alone Non-Public Network) does not rely on network functions provided by a PLMN (Public Land Mobile Network), whereas a PLMN provides network functions. This highlights the key difference between these two types of networks in terms of their operational dependencies.
