Should you take it?

  • Suits Microsoft 365 admins rolling out Copilot and agents who want a 45-minute exam that never expires.
  • Not for everyday users who only want to get better at Copilot, as the exam covers administration, data protection and governance.
  • The catch: Microsoft expects you to know Microsoft 365 security, identity and access already, so new admins should learn those before booking.
  • If you'd rather build AI solutions on Azure than administer Copilot, AI-901 fits better, provided you know Python coding syntax.

Who is the AB-900 exam for?

Microsoft 365 admins who now have to look after Copilot and agents. Microsoft expects you to be familiar with Microsoft 365, including core services, security, identity and access, data protection, and governance, along with Microsoft 365 Copilot and agents. The catch: it is a fundamentals exam, so it shows you know the basics of the admin side, not that you build agents.
