Question: What is the primary outcome of the X2 Setup procedure between two eNodeBs (eNBs) in an Evolved Universal Terrestrial Radio Access Network (E-UTRAN)?
Option 1: Establishment of a new User Equipment (UE) connection over the X2 interface.
Option 2: Modification of existing radio resource allocation for ongoing sessions.
Option 3: Exchange and update of application-level configuration data, resetting the X2 interface.
Option 4: Initiation of a handover procedure for UEs between the two eNBs.
Explanation: The X2 Setup procedure is designed to facilitate the exchange of application-level configuration data necessary for interoperability between two eNBs over the X2 interface, updating the configuration and resetting the interface for a fresh start with new settings.
