Been and failed 291 now, resitting next week.
It's basically a big DNS exam with some SUS and then a few varied questions on all the rest.
-I failed on DNS only - I got two SIMs on that and plenty of others too. Must know all the tabs backwards and forwards, I'm making little card copies of the tabs of server and zone properties to get to know them.
-Lots of SUS, in detail
-Two very simple subnetting questions, no recursive subnetting
-Couple of ICS questions
-No WINS at all
-No Wifi LEAP/PEAP of any sort
-No 'what windows version uses Ms-CHAP v2 questions', though I'll probably get those next time instead.
