Question: In the context of E-UTRAN, which scenario involves transferring the COUNT value from the SeNB to the MeNB using the EARLY STATUS TRANSFER message?
Option 1: DAPS Handover between two eNBs
Option 2: Conditional Handover with Dual Connectivity
Option 3: Conditional PSCell Addition in EN-DC
Option 4: Inter-RAT Handover from LTE to UMTS
Explanation: During a Conditional Handover with Dual Connectivity, the EARLY STATUS TRANSFER message transfers the COUNT value related to forwarded downlink SDUs from the Secondary eNB (SeNB) to the Master eNB (MeNB), ensuring seamless handover and maintaining data integrity across the dual-connected setup.
