Two routers functioning as DRother on a broadcast link will establish which kind of OSPF neighbor state with each other?

A.
Exchange

B.
2Way

C.
ExStart

D.
Full

Explanation:
OSPF Adjacency States
* Down Initial state, waiting for start event
* Init Hello sent but bidirectional communication not established
* 2Way Hello received, bidirectional communication established
* ExStart Routers negotiate who in in charge of LSDB sync
* Exchange Exchange LSA headers, if missing data send LSR
* Full LSDBs fully syncd

OSPF Router Types
* DR forms Full adjancies with all DROthers and the BDR
* BDR forms Full adjancies with the DR and all DROthers, does not advertise learned link state info
* DROther Other routers on a broadcast link
* DROthers form 2Way adjacencies with each other
