i can only say this: know it inside and out. The same goes for OSPF, EIGRP, BGP, multicast, router functions, and IPv6. I know this answer wasn't the least bit helpful, but if it is listed in the exam topics then you flat out need to know it regardless if there's one question or 10 questions on the exam. You don't want to be a paper CCNP.
I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)
