What Is AZ-900 Certification?

What the AZ-900 Certification Actually Is

The Microsoft Certified: Azure Fundamentals credential-identified by exam code AZ-900-is Microsoft Corporation's entry-level validation that a candidate understands cloud concepts and core Azure services. It is not a specialist or associate-level exam. It is a fundamentals exam, which places it at the base of Microsoft's certification hierarchy and makes it the natural first step before pursuing role-based credentials like Azure Administrator (AZ-104) or Azure Developer (AZ-204).

The "AZ" prefix in the exam code signals the Azure product family. The "900" suffix, by Microsoft convention, designates a fundamentals-tier assessment. Understanding this naming logic is explored in depth in the article on AZ-900 Meaning, but practically speaking, it means the exam tests conceptual breadth rather than hands-on configuration depth.

Because Microsoft intends the AZ-900 as a common starting point, the skills measured are designed for candidates who may be new to IT entirely, or who come from non-technical backgrounds such as sales, finance, or project management and need to speak fluently about cloud services. It is equally valid for IT professionals with infrastructure, database, or software backgrounds who want a formal credential anchoring their Azure knowledge.

Exam At a Glance: Format, Time, and Score

Before studying a single flashcard, you should understand the mechanics of the assessment itself. Several of these details directly shape how you should prepare.

A few details in that table deserve emphasis. First, the 45-minute exam window is tight relative to the breadth of material. That is roughly one minute per question at the high end of the question range. Second, Microsoft uses a scaled score of 700 as the passing threshold-this is not a raw percentage. Because the scale runs from 1 to 1,000 and some items may be unscored, you should not interpret 700 as needing exactly 70% of questions correct.

Third, and importantly: there is no penalty for guessing. Every question you leave blank is a guaranteed zero. A guess, however, carries a nonzero probability of being correct. Never submit the exam with unanswered questions.

The Three Domains You Will Be Tested On

Microsoft divides the AZ-900 exam into three content domains. Every question maps to one of these domains, and their percentage weights determine where you should invest your study time. The full domain-by-domain breakdown is covered in the AZ-900 Exam Domains 2026: Complete Guide to All 3 Content Areas, but here is what each domain covers at a structural level.

Notice that Domain 1 is conceptually the easiest but also the smallest slice. Domain 2 carries the most exam weight and the most concrete service-level detail. Domain 3 sits in the middle on both dimensions. This distribution should directly shape your study schedule.

Who Should Take the AZ-900?

Microsoft's official audience statement covers a wide range of candidates, and that breadth is intentional. The AZ-900 is suited for:

• IT professionals transitioning to cloud roles-infrastructure engineers, database administrators, and software developers who want to formalize their Azure foundational knowledge before pursuing a role-based certification.
• Business stakeholders-project managers, procurement teams, sales engineers, and executives who make or influence decisions about cloud adoption and need credible fluency in cloud concepts.
• Career changers and students-individuals with no existing IT credentials who want a verifiable, vendor-issued starting point on a Microsoft certification path.
• Employees undergoing organizational cloud migrations-teams where understanding shared responsibility, governance, and cost management is operationally relevant even without hands-on technical roles.

The question of whether this credential moves the needle on compensation and hiring is answered in detail in the AZ-900 Salary Guide 2026: Complete Earnings Analysis and Is the AZ-900 Certification Worth It? Complete ROI Analysis 2026. The short version: the AZ-900 functions most powerfully as a signal and a stepping stone rather than a standalone differentiator in competitive technical hiring markets.

Registration, Scheduling, and Cost

Registration for AZ-900 runs through Pearson VUE, which offers two delivery modes: an in-person proctored test at an authorized test center, or an online proctored session delivered through the OnVUE platform from a private location. Students and educators may also have access to scheduling through Certiport, depending on their institution's agreements with Microsoft.

The exam fee is $99 USD in the United States. Microsoft and Pearson VUE price exams regionally, meaning the cost in your country may be higher or lower than the U.S. rate when converted-it is not simply a currency conversion of $99. Check the Pearson VUE scheduling page for your specific country's pricing before registering.

One important restriction applies specifically to Fundamentals exams: Microsoft Learn is not accessible during the AZ-900. Some Microsoft exams allow candidates to reference documentation during the test; Fundamentals exams do not. Everything you need to answer questions must come from memory.

What the Exam Actually Tests: Topic-Level Detail

The AZ-900 uses a proctored, computer-based format. Microsoft does not pre-announce exact question types, but the exam can include multiple-choice questions, multiple-select questions, drag-and-drop ordering, and other interactive components. Expect that most questions will be multiple-choice with four answer options, but do not assume uniformity.

Question scenarios on AZ-900 tend to be brief. A typical item might describe a business requirement-"a company needs to ensure their application remains available if one Azure datacenter fails"-and ask which Azure feature or service addresses that requirement. This means you need to understand not just what each service is called, but what problem it solves.

Concrete topics that appear with high frequency based on the official skills outline include:

• The difference between availability zones and availability sets
• When to use Azure Blob Storage versus Azure Files versus Azure Disk Storage
• What Microsoft Entra ID does versus what on-premises Active Directory does
• How Azure Policy enforces compliance compared to role-based access control (RBAC)
• The distinction between CapEx and OpEx in a cloud context
• What the shared responsibility model shifts to the customer under IaaS versus PaaS versus SaaS
• How resource groups relate to subscriptions, and subscriptions to management groups

Practicing with realistic questions is one of the highest-leverage activities you can do before exam day. The AZ-900 Exam Prep practice tests on this site are structured to reflect the domain weights above, with Domain 2 questions carrying the highest representation. The article on Best AZ-900 Practice Questions 2026: What to Expect on the Exam explains exactly how to use practice exams diagnostically rather than just as a confidence check.

Preparing Domain by Domain

Generic study advice-Pomodoro sessions, spaced repetition apps, Feynman technique-has value, but only if you apply it to the right material in the right sequence. Here is a domain-driven framework that maps study weeks to AZ-900's actual structure.

The AZ-900 Study Guide 2026: How to Pass on Your First Attempt goes deeper on resource selection and how to sequence Microsoft Learn modules against the domain weights above. For a realistic sense of how demanding this preparation actually is, How Hard Is the AZ-900 Exam? Complete Difficulty Guide 2026 provides an honest assessment.

Does the AZ-900 Expire?

This is one of the most practically important facts about the credential: Microsoft Fundamentals certifications do not expire. Renewal does not apply to the AZ-900. Once you pass, the certification remains active on your Microsoft Learn transcript indefinitely.

This stands in contrast to Microsoft's associate and expert-level certifications, which require annual renewal through a free online assessment or risk expiring. The permanent validity of the AZ-900 makes it a particularly low-risk investment-you pay the exam fee once, pass once, and the credential persists on your record without ongoing action required.
