Your best bet is to start here:
http://www.microsoft.com/learning/en/us/certification/cert-sql-server.aspx
FYI, second link in Google with : Sql server database certification.
Dig into the second tab and the specific test information. This is the 'official' information from microsoft.
Avoid looking for brain dumps. They are out there. MS will also permanently blackball you and remove any prior certs if you're nailed using them.
Never stop learning, even if it hurts. Ego bruises are practically mandatory as you learn unless you've never risked enough to make a mistake.
