Question: What is the primary outcome for the eNB and MME after completing the S1 Setup procedure on the S1 interface?
Option 1: Establishment of UE-associated signaling connections
Option 2: Exchange and update of application level data for interoperability, erasing existing configuration data
Option 3: Immediate initiation of user plane data transfer between eNB and MME
Option 4: Automatic release of all currently active UE contexts
Explanation: The S1 Setup procedure ensures the eNB and MME can interoperate by exchanging necessary application level data, updating nodes with new configuration data and overwriting existing settings, crucial for harmonized operation on the S1 interface.
