AZ-900 Azure Fundamentals: Official Exam Format, Cost, and Why It Never Expires

What AZ-900 Certification Actually Certifies

AZ-900 is Microsoft's entry point into the Azure ecosystem, and it's explicitly designed as a conceptual, non-technical credential — it validates a broad understanding of cloud concepts, core Azure services, security, governance, privacy, compliance, and pricing without requiring deep technical or hands-on administration experience. This is a genuinely different bar than Microsoft's role-based Associate and Expert-level Azure exams (AZ-104, AZ-305, and so on), which do test hands-on configuration and administration skill.

With more than 1.2 million professionals having earned this credential since launch, AZ-900 has become, by volume, the single most-taken cloud certification in the industry — a scale that puts it well ahead of comparable foundational credentials from AWS or Google Cloud. That popularity has a  practical upside for candidates: the study ecosystem around AZ-900 is enormous, and Microsoft itself makes the core preparation material freely available through Microsoft Learn.

Who AZ-900 Exam Is For (and Who It's Not For)

There are no prerequisites of any kind — no required prior certification, no cloud experience, and no programming background. Microsoft's own positioning increasingly frames this exam as relevant beyond purely technical roles: business-facing staff, project managers, sales professionals, and analysts who work alongside Azure teams are a genuine part of the intended audience, not just aspiring engineers.

For technical professionals already working hands-on with Azure, AZ-900 functions less as a significant career milestone on its own and more as a quick, low-friction credential — its  value for that audience lies in how it smooths the transition into role-based Associate-level exams like AZ-104, since the conceptual foundation it builds (shared responsibility model, service categories, pricing and support structures) recurs throughout Microsoft's more advanced Azure certifications. It's a poor fit for someone hoping a certification alone will make them job-ready as an Azure engineer — AZ-900 validates cloud literacy, not hands-on administration capability, and employers generally understand it that way.

Exam Format and Structure

The exam runs 45 minutes of actual exam time, with total seat time closer to 65 minutes once intro screens and an optional post-exam survey are factored in. Question counts vary by exam form, but Microsoft's own guidance and third-party reporting consistently put the range at approximately 40 to 60 questions, mixing single-choice and multiple-choice items with drag-and-drop, active-screen, build-list, case-study, and short-answer formats — a genuinely broader mix of interactive formats than a pure multiple-choice exam, worth practicing with Microsoft's own exam sandbox tool beforehand so the format itself isn't a surprise on test day.

If you fail, Microsoft's official retake policy allows a first retake 24 hours after the initial attempt, with longer waiting periods applying to subsequent retakes — full details are published directly on Microsoft's exam retake policy page, worth checking directly if you're facing a second or third attempt.

Domains and Topics Covered

Microsoft's most recent skills outline revision (dated July 20, 2026, following a smaller update in January 2026 that touched identity and resource-management content specifically) organizes AZ-900 into three weighted domains:

Azure Architecture and Services carries the largest share, covering core compute, storage, networking, and database service categories, along with the practical distinctions between IaaS, PaaS, and SaaS delivery models. The two more recent skills-outline revisions specifically sharpened coverage of Microsoft Entra ID (the renamed successor to Azure Active Directory — a naming change that's tripped up candidates studying from pre-rename material), Microsoft Defender for Cloud, and Microsoft Purview, so candidates working from older study guides should specifically verify their material reflects Entra ID terminology rather than the older Azure AD naming.

Cost Breakdown

The exam costs $99 USD in the United States, with Microsoft pricing it by country or region rather than a single fixed global rate — for context, third-party sources cite roughly ₹3,691 in India or approximately ¥13,200 (including tax) in Japan as regional equivalents, so the effective cost varies meaningfully depending on where you're testing. Each retake requires paying the fee again in full; there's no discounted or free retake built into the standard price.

One genuinely useful cost-saving path worth knowing about: Microsoft periodically runs free Virtual Training Days, two-day online events that include a complimentary AZ-900 exam voucher on completion — a way to fully offset the $99 fee for candidates willing to attend the associated training sessions.

Prerequisites and Eligibility

None. This is one of the most genuinely open-door certifications covered on this site — no required prior certification, no minimum experience, no educational prerequisite, and no technical background of any kind needed to register and sit the exam.

How AZ-900 Exam Is Scored and What Passing Requires

You need a scaled score of 700 out of a possible 1,000 to pass. Microsoft is explicit that this doesn't translate to a simple "70% of questions correct" — the scaled scoring model accounts for the relative difficulty of the specific questions a given candidate receives, so attempting to calculate an exact number of correct answers needed based on the 700 threshold isn't a reliable strategy. If you fail, Microsoft provides a score report broken down by domain, which is worth using directly to target weak areas before a retake — the most common recovery advice isn't to study more advanced Azure administration topics, but to shore up fundamental conceptual gaps in cloud service models, governance terminology, and pricing/support structures.

Renewal and Recertification

This is one of the most distinctive features of AZ-900 relative to nearly every other certification covered on this site: it does not expire. Once earned, Microsoft Certified: Azure Fundamentals is valid indefinitely, with no renewal fee, no continuing education requirement, and no periodic retake needed to keep it active — a genuine, permanent credential rather than one requiring ongoing maintenance. This stands in direct contrast to AWS's comparable foundational credential (AWS Certified Cloud Practitioner, CLF-C02), which requires renewal every 3 years, and even to some of Microsoft's own more advanced role-based Azure certifications, several of which do carry renewal requirements.

One nuance worth flagging: while the credential itself doesn't expire, the underlying exam content isn't frozen — Microsoft periodically updates the AZ-900 skills outline to reflect current Azure terminology and features (as it did in January and again in July 2026), with the English version updated first and localized versions following later. This doesn't affect anyone who's already passed and holds the certification, but it does mean study material should always be checked against the current skills outline date before relying on it.

How AZ-900 Exam Compares to Its Closest Alternative

The most direct cross-platform comparisons are AWS Certified Cloud Practitioner and Google Cloud's foundational offerings, all three occupying essentially the same niche: a non-technical, conceptual entry point into a major cloud platform, aimed at both aspiring technical professionals and business-facing staff who work alongside cloud teams. The most meaningful practical difference among them isn't difficulty or format — it's certification validity: AZ-900 never expires, while AWS Certified Cloud Practitioner requires renewal every 3 years, a genuine and durable distinction worth factoring into which platform's foundational credential to pursue first if you're not yet committed to one cloud ecosystem specifically.

Within Microsoft's own Fundamentals series, AZ-900 sits alongside sibling credentials covering the same $99/45-minute/700-to-pass/no-expiration format applied to other Microsoft platforms: AI-900 (recently succeeded by AI-901), DP-900 (data), SC-900 (security), and MS-900 (Microsoft 365). Many candidates collect several of these together, since foundational concepts like Microsoft Entra ID and role-based access control recur across the series, making each additional Fundamentals credential meaningfully faster to prepare for once you've passed the first.

 Preparation Timeline

For someone with some general IT or cloud-adjacent background, a commonly cited timeline is 2 to 4 weeks at roughly 5 to 8 hours per week, working through Microsoft's own free Microsoft Learn modules and hands-on practice inside a free Azure account (creating a virtual machine, storage account, and virtual network firsthand meaningfully reinforces the conceptual material more than reading alone). Candidates with existing IT experience sometimes pass in under a week of focused study.

For someone with no prior IT or cloud background at all, extending that timeline modestly and specifically prioritizing the Azure Architecture and Services domain given its largest weighting, along with genuinely understanding the shared responsibility model and the practical distinctions between IaaS, PaaS, and SaaS, tends to produce more reliable results — these foundational distinctions recur throughout the exam in varied phrasing, and Microsoft's exam-style wording itself is worth getting comfortable with beforehand given the short 45-minute window.
