It spanked me again!

This was my second try. I'm disappointed to say the least.
Technology 64%
Implementation & Operation 85%
Planning & Design 81%
Troubleshooting 76%
First exam had a several ISDN questions. This time, none. I did 2 simulations. One troubleshooting OSPF config across 3 routers. One looking at switch info, MAC tables, root calculations, etc - mini-test.
Q. Given a destination IP address in a packet, how can you tell from the switch which MAC address the packet will be sent out on?
Comments: I was pretty confident going in. I've been scoring 90-100% on the Self-Test exams in Certification mode. While helpful, the Self-Test questions are not as tough as the real exam, IMHO. Only 4 simulations in Self-Test (could use more). I feel like you have to know "everything" about "everything" on routers and switches to pass the f...ing exam!
