Question: What is the primary purpose of a Network Slice Instance Identifier (NSI ID) in a 5G Core Network (5GC)?
Option 1: To uniquely identify a Network Slice Instance (NSI) within a Public Land Mobile Network (PLMN) or Shared Network and Policy Network (SNPN) when multiple instances of the same Network Slice are deployed.
Option 2: To associate a Network Slice with a specific User Equipment (UE) for personalized services.
Option 3: To differentiate between various Service and Network Slice Selection Assistance Information (S-NSSAI) within a single NSI.
Option 4: To identify the geographical location of a Network Slice Instance within a PLMN.
Explanation: The correct answer highlights the key function of an NSI ID, ensuring distinguishability among multiple instances of the same Network Slice within a network, facilitating efficient management and operation in the 5GC. This is crucial for network slicing's promise of customized, scalable, and secure connectivity services.
