Question: What type of information is negotiated/exchanged between the RNC and Node B over the Iub interface, aside from dedicated connection support for UE to SRNC communication?
Option 1: Only Cell Handover Parameters
Option 2: Solely Logical O&M (Operations & Maintenance) Data
Option 3: Both Broadcast Channel Control/Content Information and Logical O&M (Operations & Maintenance) between Node B and RNC
Option 4: Exclusively UE (User Equipment) Capability Exchange
Explanation: The correct answer reflects the nuanced understanding of the Iub interface's role in managing radio resources. It accurately identifies that, beyond supporting dedicated connections, the RNC and Node B exchange information for controlling and transporting data on broadcast channels, as well as logical Operations & Maintenance (O&M) data, highlighting the interface's significance in both service provisioning and network management.
