sounds reasonably straightforward... my practice tests were asking me which IP's could be used in certain subnets so i got used to working it out on my fingersI passed my 290 with no revision whatsoever. VERY easy.
70-291 is a lot harder but still not too difficult if you've got plenty of experience managing DHCP, DNS, WINS, WSUS and multi-site topologies. It also helps to understand IP addressing properly as well. Learn to calculate subnets in your head (or at least learn how to do it using Windows Calculator). You'll get a few questions where you need to work out what subnet mask to use for a network with a given number of nodes, and probably one where you get given a subnet that needs breaking down into smaller subnets. As I said, still not that difficult.
Sometimes you don't. Out of the 70 odd official questions, you'll only get asked 44 of them.
The tests are designed to make you fail if you aren't very good on a given subject. If you get questions wrong on say DHCP, it'll keep giving you more questions on that subject. Sometimes you even get asked the same question two or three times. If you get most of your questions correct as you progress through the exam you'll get a larger variety of questions overall. I got a couple of questions on subnetting and they're normally multiple answer ones (choose 3, etc...)
Get the CBT Nuggets training videos. They're very good and cover all bases for the Microsoft exams.
+1, I got 1000/1000 for the vista, was a piece of piss!Why did you do the 70-270 over the 70-620?
They both count as the necessary "Client" exam, but the 620 is so much easier! It's also for a more current OS so it'll be valid for longer, and instead of getting an MCP you get an MCTS. As I said, it still counts towards an MCSA/E though.
However, congratulations on passing
