I'm currently studying for this exam too so I could well be wrong, forgive me if I am...
My understanding is that the dr and bdr are there to reduce LSA traffic when there are numerous routers on a shared network - instead of everyone talking to everyone it's everyone to a dr. On a point to point link there are only two routers so the excessive traffic problem won't occur and the DR/BDR aren't required. As such it's just a case of configuring each router to know about the other (using the neighbor statement), after this they send the usual hello's to each other to build and maintain the link state database. If this is wrong can someone correct me.
