What makes the AB-900 hard
AB-900 is not a Copilot how-to exam, it is a governance exam wearing a Copilot badge: Purview DLP versus sensitivity labels, DSPM for AI versus Insider Risk, conditional access versus Identity Secure Score. The exam spends more time on data protection and governance than on Copilot itself, because the real job of an AB-900 certified admin is making sure Copilot does not surface data it should not touch. That is the domain most candidates underestimate.
The exam runs 40 to 60 questions in 45 minutes, 65 minutes total seat time, with a pass mark of 700 out of 1000. At US$99 it is one of the cheaper Microsoft exams, but a retake costs another US$99 and a 24-hour wait, and AB-900 renews annually through a free Microsoft Learn assessment.
This pack has 89 practice questions for the AB-900, covering Microsoft 365 core objects, Purview governance, and Copilot and agent administration, so the licensing and oversharing questions Microsoft favours are not a surprise on exam day.
