So I failed 70-649 today with the following scores:-
70-640 (AD): 1000 - 9 Questions
70-642 (Network Infrastructure): 583 - 19 Questions
70-643 (Applications): 880 - 20 Questions
As you know they take your lowest score as the 'overall' score so I ended up with 583/1000...

Main areas which I need to focus study on are:-
NAP (particularly when used with 802.11x)
VPN Technologies - When/where to use them
Event Logging to other servers and 'where' to monitor events in this setup.
Any tips / advise in these areas would be greatly appreciated.
Annoyingly, I booked this exam before Christmas and therefore before the free second shot offer! Plan to refocus my studies on networking and set a plan to retake next week. In addition, my closest test centre is over 150 miles away (2 hour train journey!) and when sitting the exam you can hear the Microsoft classroom training next door so it's hard to concentrate.

There used to be a test centre 5 minutes walk from where I work, but that closed down because they weren't making any money from the tests.
I wasn't tested on this specifically but I know it's one of my weak areas. Does anyone have reference material for IPv6 networking, addresses configuration and specially how to work out ranges / allocations / work out subnets etc?
