Question: What are the two key components that comprise the CellGlobalIdUTRA, which identifies a UTRAN cell uniquely worldwide?
Option 1: Cell Identity alone, which is a unique numerical value
Option 2: PLMN (Public Land Mobile Network) Identity and Cell Identity
Option 3: Tracking Area Code and Location Area Code
Option 4: Cell Global Identity and UTRA Absolute Radio Frequency Channel Number
Explanation: The CellGlobalIdUTRA is composed of two essential parts: PLMN-Identity, identifying the Public Land Mobile Network, and CellIdentity, a unique identifier for the cell within the UTRAN. Together, these components ensure the global uniqueness of a UTRAN cell's identity.
