www.measureup.com or www.transcender.com are both good sites. Trancenders are harder but tend to be more like the actual questions. measureups are cheaper and endorsed by microsoft so take your pick. keep away from anything that says "real exam questions" or "braindump" they are a waste of your money, time, and you can risk being decertified and banned from all future tests.
"The secrecy of my job prevents me from knowing just what it is that I do."
Another hint for finding questions and material is to go to google.com and type in "70-271 questions" or something like that. There are so many free resources out there. Just like spree610 says, avoid braindumps, or any site that advertises real test questions from the cert test.
Good luck.
Experience is a harsh teacher. She gives the test first, the lesson afterwards.
