I took TCP/IP only minutes ago and failed, by less that 1 question.  This test is not easy.  What surprised me most were the SPECIFIC questions on PERFORMANCE MONITOR and NETWORK MONITOR.  Stuff I had never seen before in any study guide.  What services in PerfMon provide you with such and such specific info.  Yikes. 

Lots of Scenario Q's on DHCP and UNIX clients mixed in with Win clients.  2 Drag and Drops, one with 4 subnetting scenarios on it (miss one subnet mask and miss the whole Q!!!)  One of the DnD's was about 3 subnets, a server on each net comprised of a DHCP server in the middle net, a WINS server on the right net and a blank server on the left net.  Clients included a NON-Wins client on the left and a regular client on the right.  Goal was to allow all clients to participate in DHCP and the non WINS client to use wins.  

Well, good luck, I am going back in two days to pass that bastard.
