Certificate of Completion

Finish the course. Prove it.

Complete all 44 labs and you can download a certificate of completion with your name, the skills you practised and a unique ID. Challenges are optional. Anyone can check it on a public verification page — and add it to LinkedIn in one click.

  • Not self-declared. Before issuing, our server re-runs the grader on every lab you saved, so a checkbox in your browser is not enough.
  • Verifiable. Every certificate has its own page at examitlab.com/verify/<ID>.
  • Honest. It certifies that you completed this course. It is independent training, not an official certification.

Sample certificate — name and ID are fictional.

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 44 original tasks are mapped to Microsoft's AB-900 study guide, skills measured as of 14 October 2026. They practise selected identity, governance, Copilot and agent workflows. Prompt scheduling, app registration creation and some service-object concepts are explained rather than fully simulated. Use the official study guide and Microsoft Learn alongside this course.
Is there a certificate at the end?
Yes. When all 44 labs are complete you can issue a certificate of completion in your account: a PDF with your name and a unique ID, an Add to LinkedIn link and a public verification page. Before issuing, the server re-runs the course grader on every lab you saved, so it reflects work you really did. It certifies completion of this course; it is independent training, not an official certification.
How is this different from a Microsoft Learn sandbox or a trial tenant?
Each task supplies fictional users, evidence and a prepared starting state, with guidance and checks on the resulting configuration. It is a bounded teaching simulation of selected administration workflows; changes never reach a real Microsoft tenant.

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.
