Explanation :

Answer: A) Configure a seperate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface Explanation: If you have a serial port configured with multiple DLCIs connected to multiple remote sites, split horizon rules stop route updates received on an interface from being sent out the same interface.
