The 70-643 exam, officially titled Windows Server 2008 Applications Infrastructure, Configuring, is the Microsoft exam you pass to earn the MCTS certification, a credential at the Professional level. Passing it confirms the skills defined in the official exam outline, and it is associated with related credentials such as MCTS: Windows Server 2008 Applications Infrastructure Configuration, MCPD: Windows Server 2008.

The 70-643 exam includes 40-60 questions and gives you 120-150 to finish them. That is a tight pace per question, so get used to reading each stem once, flagging anything uncertain, and moving on rather than getting stuck. Running timed practice tests in the Lead2Passed desktop or online test engine is the most reliable way to build that rhythm before exam day.

The passing score for the 70-643 exam is 700/1000, and the official registration fee is USD 165 (varies by region). Keep in mind that a failed attempt means paying USD 165 (varies by region) again in full to retake it, so book your slot only when your scores on Lead2Passed practice tests sit consistently above the passing line.
