Question: In an E-UTRAN, which of the following scenarios involves sending a DATA FORWARDING ADDRESS INDICATION message from the MeNB to the SeNB?
Option 1: During a handover procedure without Dual Connectivity
Option 2: During Conditional Handover with Dual Connectivity
Option 3: When initiating a new E-RAB setup without handover
Option 4: For routine synchronization between MeNB and SeNB
Explanation: The correct answer is Option 2 because, during Conditional Handover with Dual Connectivity, the DATA FORWARDING ADDRESS INDICATION message is used for transferring data forwarding related information from the Master eNodeB (MeNB) to the Secondary eNodeB (SeNB), ensuring seamless data forwarding during the handover process in a Dual Connectivity scenario.
