Which of the following about F-pipes is FALSE?

F-pipes use SAPs in the form of port: DLCI (e.g. 1/2/3:65).

To the customer, the PE appears as a native Frame Relay UNI (User Network Interface).

Multiple Frame Relay circuits can be mapped to a single F-pipe service on the Alcatel-Lucent 7750 SR.

The MPLS control word is required because the Frame Relay header is not encapsulated in the frame.
