What are three characteristics of the OSPF routing protocol? (Choose three.)
A.
It converges quickly.
B.
OSPF is a classful routing protocol.
C.
It uses cost to determine the best route.
D.
It uses the DUAL algorithm to determine the best route.
E.
OSPF routers send the complete routing table to all directly attached routers.
F.
OSPF routers discover neighbors before exchanging routing information.
B. is incorrect because OSPF supports VLSM and that is used with classes protocols.
D. is incorrect because DUAL is an algorithm that is used with EIGRP.
OSPF uses Dijkstra algorithm.
E. is incorrect. That is something that RIP would do. OSPF only sends out changes and segments the routers into area’s.
