Question: What is the primary purpose of the IAB-IP-AddressIndex Information Element in Radio Resource Control (RRC) protocol?
Option 1: To authenticate User Equipment (UE) for security procedures
Option 2: To manage Quality of Service (QoS) parameters for bearers
Option 3: To identify a specific configuration of an IP address
Option 4: To initiate handover procedures between different base stations
Explanation: The IAB-IP-AddressIndex is utilized within the RRC protocol to uniquely identify a particular configuration of an IP address, facilitating effective management and communication within the network. This aligns with the need for precise identification of IP configurations in telecommunications, ensuring seamless data transfer and resource allocation.
