Microsoft Certification AZ-900
On-device AI scores your readiness, builds an adaptive study plan, and flags topics fading from memory — before they cost you the exam.
Get exam-ready for AZ-900 (Microsoft Azure Fundamentals) on iPhone or iPad. Azure Mastery uses on-device AI to predict your readiness score, build a personalised study plan, and surface topics you're forgetting. Core study stays on-device and works offline; optional sync uses your private iCloud account.
The exam
AZ-900 is the foundational Azure certification — the standard starting point for cloud careers in the Microsoft ecosystem. It's accessible enough for sales engineers, project managers, and finance partners, but rigorous enough that a meaningful share of candidates fail their first attempt. The exam validates that you can describe core Azure services, recognise cloud computing concepts (IaaS, PaaS, SaaS), and explain Azure architecture, governance, identity, and security.
AZ-900 is intentionally non-technical at the surface — it doesn't expect you to write PowerShell scripts or design network topologies. What it does expect is a clear conceptual map: regions, availability zones, resource groups, the shared responsibility model, Azure Policy, and the defence-in-depth security model — all explained in terms a non-engineer can defend in a meeting.
Microsoft updated the AZ-900 skills outline on 14 January 2026. Every question in Azure Mastery's AZ-900 bank is mapped to the current outline — no leftover questions on retired features. Read the official outline at learn.microsoft.com.
Skills measured · January 2026
Three domains, with weights set by Microsoft's January 2026 update. Every domain summary below is paraphrased from the official skills outline; the bullet-level objectives in Azure Mastery are tagged so you always know which domain you're being tested on.
The why of cloud computing — before any Azure-specific knowledge. Expect questions on the shared responsibility model, public/private/hybrid cloud trade-offs, the consumption-based pricing model, serverless, and the three service-type models (IaaS, PaaS, SaaS) with use-case examples. Around 9–18 questions per sitting. Smallest domain — but the conceptual foundation everything else builds on.
The largest domain. Covers the architectural hierarchy (regions, region pairs, availability zones, datacenters, resource groups, subscriptions, management groups); compute and networking (virtual machines, scale sets, containers, functions, virtual networks, peering, DNS, VPN Gateway, ExpressRoute, public/private endpoints); storage services and tiers; and identity, access, and security (Microsoft Entra ID, MFA and SSO, Conditional Access, Azure RBAC, Zero Trust, the defence-in-depth model, and Microsoft Defender for Cloud). Around 14–24 questions per sitting.
Cost management factors and the pricing calculator; Microsoft Purview, Azure Policy, and resource locks; Azure portal, Cloud Shell, CLI and PowerShell, Azure Arc, infrastructure as code (IaC), and ARM templates; monitoring with Azure Advisor, Service Health, and Azure Monitor (including Log Analytics, alerts, and Application Insights). Around 12–21 questions per sitting.
Designed for AZ-900
Azure Mastery ships with 380 AZ-900 practice questions, every one written specifically against the current (January 2026) skills outline. Each question carries a domain tag mapped to the official three domains, so you always know which area you're being tested on and where your weak spots are clustered.
The on-device Exam IQ engine predicts your AZ-900 score before you sit the exam. After roughly 30 questions it has enough signal to give a confidence-scored prediction (e.g. "786 ±37, 68% confidence") — and tells you the specific topics that are dragging your readiness down. No vague "study more" advice; just a ranked list of objectives where improvement would move your score the furthest.
The adaptive study plan rebuilds itself from your answer history. Get something wrong on resource locks? You'll see another resource-locks question in the next session. Master "describe IaaS" three sessions running and the engine backs off, surfacing newer material. The plan optimises for the gap between where you are and the 700 pass score, not for blind volume.
Knowledge decay tracking is the secret weapon for foundational exams like AZ-900. The same domain you mastered six weeks ago is the domain you'll forget by exam day if you stop revising. Azure Mastery tracks every topic's decay curve and flags topics approaching expiry — the padlock icon on the Today screen is your "revisit before you forget" cue.
Real exam simulation mode runs at AZ-900's actual length and time pressure: a randomised question set drawn from the full 380-question bank, 45-minute timer, no jumping back to flag-and-review. It's the closest you can get to the test centre experience without sitting the exam.
Answer Coach turns each missed answer into a private, grounded lesson: the misconception, key distinction, and rule to remember. It always uses authored certification guidance; on supported devices, an optional on-device model may rewrite the note only when it passes grounding checks.
During your first week, Aura adapts the next step as you go. Every session ends with a concise recap of what changed, what to focus on, and the best follow-up.
Everything essential runs on-device. Your answer history, readiness gauge, and coaching stay private. Optional sync uses your private iCloud account; there is no Azure Mastery account, tracking, or external processing server.
2-week revision plan
Most candidates with prior IT experience pass AZ-900 after one to two weeks of focused revision. Below is a two-week plan that maps onto Azure Mastery's domains, simulator, and decay alerts. Adjust pace to taste — the readiness gauge tells you when you're done, not the calendar.
Inside the app
AZ-900's question bank uses the same formats Microsoft puts on the live exam — not just multiple choice. Each visualisation below is a faithful mock of how the type renders inside Azure Mastery on iPhone and iPad. Exam-simulator mode runs all of them at full 100-minute length with no flag-and-review jumps, mirroring Pearson VUE.

App exclusiveFrequently asked
The AZ-900 voucher is USD $99 in the United States. Pricing varies by region — in the UK it's typically around £77. Microsoft sometimes runs free-voucher promotions for events such as Microsoft Build or Microsoft Ignite, so check your Microsoft Learn profile for any active offers before booking.
No. Microsoft Fundamentals certifications — including AZ-900, DP-900, AI-901, MS-900, and PL-900 — do not expire. Once you pass, the certification is yours for life. (This is different from Associate and Expert certifications such as AZ-104 or AZ-305, which require an annual free renewal assessment on Microsoft Learn.)
The first retake is allowed after 24 hours. Second and third retakes each require a 14-day wait. Microsoft caps retakes at five attempts per 12-month rolling period. Each attempt requires a new voucher purchase.
Most candidates with prior IT experience pass after one to two weeks of focused revision. If cloud computing is genuinely new to you, plan for three to four weeks. Azure Mastery's readiness gauge will tell you when you're at exam-ready — don't book until it shows roughly 720 or higher predicted score with reasonable confidence.
AZ-900 first, almost always. AZ-900 is designed as the on-ramp to AZ-104 (Microsoft Azure Administrator). It takes a few weeks to prepare for and doesn't expire; AZ-104 takes two to three months and requires hands-on PowerShell and CLI knowledge. Most people pass AZ-900 to confirm cloud is the right direction, then commit to AZ-104.
Yes — that's exactly who AZ-900 is designed for. Account managers, project managers, sales engineers, and finance partners all sit AZ-900 to qualify for Microsoft Partner Network roles. The exam doesn't expect you to write a PowerShell script. It expects you to explain concepts such as region pairs, the shared responsibility model, and when a hybrid cloud is appropriate.
Where AZ-900 fits
AZ-900 is the foundational starting point for every Microsoft Azure role-based certification path. It's optional but strongly recommended — most candidates use it as a low-stakes confirmation that cloud is the right direction before committing to an Associate or Expert track.
