They are a good place to start but don't rely on them as a benchmark. Do not underestimate this exam. It is wordy and deceptive. I had all the scenario questions described by others. Probably 6 or 7 questions, each repeated with a different set of soloutions for a total of about 12 or 14 scenarios.
Ethernet is ethernet.
I had no questions on WINS, DNS, DHCP, subnet masks or default gateways. No questions on application or network protocols and other a passing reference to transport layer protocols and NDIS compatibility with NICs. Know the routable and non rotable protocols. I had the diagram of the Mesh topology. I had no token ring questions.
