Question: What is the composition of a Shared Network Area Identifier (SNA-Id) in a telecommunications network?
Option 1: SNA-Id = Location Area Code (LAC) || Cell Identity (CI)
Option 2: SNA-Id = PLMN-Id || Shared Network Area Code (SNAC)
Option 3: SNA-Id = Mobile Country Code (MCC) || Mobile Network Code (MNC)
Option 4: SNA-Id = Tracking Area Code (TAC) || Service Area Code (SAC)
