WAN Subtopics

I took the ICND 2 test last week and got 80% or above in all the categories except WAN's. I'm trying to understand what they consider to fall under this broad category so I know what to brush up on. I knew that would be a weak point of mine before I took the test so I made sure to brush up on frame-relay and encapsulations, but somehow it was my weakest topic.. Anyone have any ideas?

From what I recall; WANs include PPP, NAT, ACLs, network troubleshooting and network security.
