- AB-900 is Microsoft's Copilot and Agent Administration Fundamentals exam - not any other credential sharing this code.
- Data protection and governance is the heaviest domain, weighted 35-40% of the exam.
- The exam itself runs 45 minutes inside a 65-minute proctored appointment.
- Passing requires 700 out of a 1000-point scaled score, not a flat 70% correct.
What AB-900 Actually Certifies
Before you memorize a single bullet point, get the identity locked down. AB-900 here refers exclusively to Microsoft 365 Certified: Copilot and Agent Administration Fundamentals, a Microsoft Corporation credential focused on how administrators configure, govern, and support Microsoft 365 Copilot and the agents built on top of it. It is not a networking exam, not a cloud infrastructure exam, and not any other certification that happens to share the "AB-900" label elsewhere. Every fact on this page applies only to this Microsoft 365 credential.

Exam Logistics at a Glance
These are the mechanics candidates ask about most in the final days before scheduling. Keep this section as your quick-check before you book a seat.
- Delivery channels: Pearson VUE is the primary testing provider; Certiport is also listed, mainly for students and educators.
- Format: Proctored, computer-based delivery with the possibility of interactive item types. The exact mix of question formats is not publicly disclosed.
- Timing: The exam itself is 45 minutes long, but Pearson VUE books a standard 65-minute appointment to account for check-in and instructions.
- Language: English is the listed exam language. There is no in-exam access to Microsoft Learn documentation during the test.
- Remote option: Supported remote proctoring is available for candidates who prefer not to test at a physical center.
- Fee: The current official U.S. checkout price is not verified on Microsoft's own pricing page at the time of writing. A commonly cited third-party figure of US$99 circulates online, but treat it as unconfirmed until you see it at checkout. Exam fees, prep material costs, and any Copilot licensing charges are billed separately.
For a full pricing walkthrough - including how licensing costs and prep spend stack on top of the exam fee - see AB-900 Certification Cost 2026: Complete Pricing Breakdown.

Key Takeaway
Do not assume any specific total question count. Microsoft's typical range across its exams is 40-60 items, but that is not a documented guarantee for AB-900 specifically - pace yourself by the clock, not by a target question number.
The Three Domains, Distilled
The published exam guide breaks AB-900 into three domains. As of the most recent verification date (September 19, 2026), an English update is scheduled for October 14 - the domain names match the current live page, but the previous full outline with weights wasn't recovered for comparison, so treat the percentages below as the latest confirmed figures rather than a historical trend.
Domain 1: Identify the core features and objects of Microsoft 365 services (30-35%)
This domain checks whether you understand the building blocks Copilot and agents sit on top of - tenant structure, licensing objects, core Microsoft 365 apps, and how services interconnect.
- Recognize core Microsoft 365 services and how they relate to Copilot experiences
- Understand tenant-level objects: users, groups, licenses, and how they're provisioned
- Know where Copilot fits within the broader Microsoft 365 service stack
Domain 2: Understand data protection and governance tasks for Microsoft 365 and Copilot (35-40%)
This is the largest domain on the exam by a clear margin, so it deserves the largest share of your study time. It covers how organizations control, label, and govern the data that Copilot and agents can access.
- Data protection concepts as they apply specifically to Copilot data flows
- Governance controls: sensitivity labels, retention, compliance boundaries
- How administrative decisions in governance settings affect what Copilot and agents can surface
Domain 3: Perform basic administrative tasks for Copilot and agents (25-30%)
The smallest domain, but still nearly a third of the exam. Expect scenario-style questions about day-to-day administrative actions rather than deep architecture design.
- Basic setup and configuration tasks for Copilot within a tenant
- Fundamentals of agent administration - enabling, managing, and monitoring agents
- Applying the right administrative role or permission to a given task
For a full walkthrough of each domain with sample topic lists and study sequencing, read AB-900 Exam Domains 2026: Complete Guide to All 3 Content Areas. That guide pairs well with the broader AB-900 Study Guide 2026: How to Pass on Your First Attempt if you're still assembling your overall prep plan.
Passing Score Quick Facts
AB-900 uses a scaled score out of 1000, and the passing threshold is 700. This is not the same as needing 70% of raw questions correct - Microsoft's scaled scoring model weighs items differently, so a 700 result does not map cleanly onto a simple percentage of items answered correctly. The official pass rate for this exam is not publicly disclosed, so avoid trusting any specific percentage you see quoted online without a verifiable source.
Because there's no formal degree, prior credential, or minimum experience/training-hour requirement listed for AB-900, the passing score is effectively the only gate standing between you and the credential. For a deeper explanation of how scaled scoring works and what a "borderline pass" actually looks like, see AB-900 Passing Score 2026: Exactly What You Need to Pass. If you're trying to gauge overall difficulty rather than just the scoring mechanic, How Hard Is the AB-900 Exam? Complete Difficulty Guide 2026 covers that in more depth, and AB-900 Pass Rate 2026: What the Data Shows lays out what is and isn't publicly known about outcomes.
Who Sits This Exam
AB-900 is a Fundamentals-level credential, meaning it's built to be accessible without a formal prerequisite chain. Microsoft's own materials expect candidates to already have some familiarity with Microsoft 365, identity concepts, governance principles, and basic Copilot administration - but there's no mandatory training-hour count or reference sign-off required to sit the exam.
In practice, this attracts a mix of people:
- IT administrators expanding into Copilot and agent management responsibilities
- Compliance and governance staff who need to understand how Copilot interacts with data controls
- Career-changers using a Fundamentals badge to signal baseline Microsoft 365 knowledge
- Students and educators using the Certiport delivery channel

If you're within a week or two of your appointment, sequence your remaining review time by domain weight rather than by alphabetical topic order. This isn't a generic study calendar - it's built specifically around AB-900's own weighting.
Domain 2 Deep Pass
- Re-review sensitivity labels, retention, and data protection concepts as they apply to Copilot
- Work through governance scenario questions since this domain carries the heaviest weight
Domain 1 Consolidation
- Confirm you can identify core Microsoft 365 objects and licensing structures without hesitation
- Map how each core service connects to Copilot functionality
Domain 3 Scenario Drills
- Practice basic admin task scenarios: enabling agents, assigning roles, monitoring configuration
- Time yourself against the 45-minute limit to build pacing instincts
Light Review Only
- Skim this cheat sheet and the one-page table above
- Avoid cramming new material; confirm logistics for your Pearson VUE or Certiport appointment
Throughout your prep, running scenario-based practice questions on our practice test platform is one of the fastest ways to see how these domain weights actually show up in question form, rather than studying them as abstract percentages. Combine that with timed runs on the practice exam simulator so the 45-minute limit stops feeling like a surprise on test day.
