AB-900 practice test — frequently asked questions
- Is this AB-900 practice test free?
- Yes. You can answer the first 7 AB-900 questions free with no credit card and no sign-up. The complete bank of 104 questions is free right now for founding members: before our public launch, a free account can unlock the complete question bank for one exam of its choice. After launch, full access is a single €18.99 payment for 30 days, no subscription.
- Are these real AB-900 exam questions or dumps?
- No. Every question is original and independently written from Microsoft's published AB-900 skills outline. Using leaked exam content ("dumps") violates the certification agreement and can get a certification revoked; our questions teach the reasoning behind each objective instead, with a source reference for every answer.
- How many questions and topics does the AB-900 practice test cover?
- 104 questions across 3 topic areas: M365 services (30–35%), Protection & governance (35–40%), Copilot & agents (25–30%). The weights follow the official outline, so your topic-by-topic score shows where to study next.
- Is the AB-900 practice test updated for 2026?
- Yes. The bank was last reviewed against the 2026 AB-900 outline on 22 September 2026. Questions are re-audited whenever Microsoft changes the skills measured.
- Does ExamIT Lab have hands-on AB-900 labs too?
- Yes. Alongside the practice test, AB-900 has guided hands-on labs in a simulated admin portal — real administration tasks with hints and automatic checking, no tenant or subscription required. The first five labs are free.
