AB-900 hands-on labs — questions
- Does AB-900 have labs, and can I practise them without a tenant?
- Yes. ExamIT Lab gives you 44 guided AB-900 labs in a simulated Microsoft 365 admin center. Nothing is deployed to a real Microsoft tenant, subscription or device, so there is nothing to set up, nothing to pay Microsoft for, and nothing you can break.
- Are the AB-900 labs free?
- The first 5 labs in the learning order are free, repeatable and never expire — no credit card and no sign-up required to start. The full course of 44 labs is a one-time purchase with no subscription.
- What does a AB-900 lab look like?
- Each lab opens a realistic simulation of Microsoft 365 admin center, Microsoft Entra, SharePoint and Purview. You get a task brief, a guided or independent mode, progressive hints and a "Check configuration" button that grades the actual end state you left behind — not just the buttons you clicked.
- Do the labs cover the current AB-900 exam outline?
- The labs are mapped to the objectives in Microsoft's current AB-900 study guide, and we re-audit the mapping when Microsoft updates the skills measured. Combine them with the AB-900 practice test on ExamIT Lab for full coverage.
- How is this different from a Microsoft Learn sandbox or a trial tenant?
- A trial tenant gives you a blank environment and no feedback. These labs give you a pre-built scenario with fictional users, devices and policies, a clear goal, and automatic checking of your result — so you practise the exact administration workflows the AB-900 exam expects, in minutes, not hours of setup.
Access is per course. Sign in for account progress. After paid access expires, your saved progress is retained and the first five tasks remain free.
