Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten
PVCs associated with the subinterface. What command would make this router not use a
DR and require static OSPF neighbor definition?

A.
ip ospf network broadcast

B.
ip ospf network non-broadcast

C.
ip ospf network point-to-multipoint

D.
ip ospf network point-to-multipoint non-broadcast

Explanation:
Of the four types listed, only point-to-multipoint nonbroadcast does not use a DR
but does require the static definition of neighbors.
