The Microsoft 365 Copilot & Agent Administration Fundamentals (exam code AB-900) is the exam you pass to earn the Microsoft 365 Certified certification, a credential at the Fundamentals level. It is also connected with related credentials such as Microsoft 365 Certified: Copilot and Agent Administration Fundamentals. If you are mapping out a certification path with Microsoft, this exam is a milestone worth planning around.

The AB-900 exam includes 40-60 questions, and you have 45 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the 2Pass4sure test engine under the same time limit, so the pace feels familiar rather than frantic on the day.

You need 700 to pass the AB-900 exam, and the official registration fee is $99 USD. That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the 2Pass4sure practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.
