Question: Which of the following statements about the NR Positioning Protocol A (NRPPa) is INCORRECT regarding its functionality and scope in NG-RAN?
Option 1: NRPPa supports E-CID for E-UTRA by transferring measurements from ng-eNB to the LMF.
Option 2: The AMF actively interprets NRPPa PDUs before routing them over the NG-C interface based on the Routing ID.
Option 3: NRPPa facilitates the exchange of assistance data broadcasting information between the LMF and NG-RAN node.
Option 4: In a split gNB architecture, the NRPPa protocol is terminated at the gNB-DU.
Explanation: The correct answer is Option 2 because the AMF routes NRPPa PDUs transparently based on a Routing ID without knowledge of the involved NRPPa transaction, meaning it does not actively interpret these PDUs before routing.
