Microsoft Azure Fundamentals (AZ-900) is one of the most accessible cloud certifications — but a significant number of candidates still fail on their first attempt by underestimating how conceptual the questions are. The exam does not test hands-on skills. It tests your understanding of cloud models, Azure service categories, and pricing and compliance principles. Good practice tests teach you the why behind Azure, not just the names.
Here are the five best AZ-900 practice test options in 2026.

1. Courseiva — Best free AZ-900 practice test (most complete option)
Courseiva's AZ-900 practice test covers all three official domains — Cloud Concepts, Azure Architecture and Services, and Azure Management and Governance — with questions proportional to blueprint weights.
Here is what you get beyond a basic question bank:
Exam Readiness Score
AZ-900 tests conceptual understanding across three domains, each weighted differently. Courseiva's Exam Readiness Score combines your accuracy, domain coverage, and weak-area trends into a clear signal: when you are ready to sit the exam. No more guessing after 200 questions whether you have done enough.
Domain Proficiency Tracking
Cloud Concepts carries 25–30% of the exam. Azure Architecture carries 35–40%. Azure Management and Governance carries 25–30%. Your domain proficiency dashboard shows your accuracy per domain after every session. If your Management and Governance score is trailing, you know to spend your next session on policy, cost management, and SLA content — not cloud concepts you already know.
Per-Domain Practice Sessions
From the AZ-900 domains hub, run a session scoped entirely to one domain: 10, 20, 30, or 50 questions. Azure Architecture in isolation — compute, storage, networking, database services — is much more productive than mixed random drilling when that domain is your weak spot.
Adaptive Practice & Weakest-Target Mode
Adaptive practice adjusts your sessions based on performance. Weakest-target mode directly targets the domains and question types where your score is lowest. For AZ-900 candidates, this often surfaces Azure pricing models, SLAs, and compliance frameworks — the concepts most people underestimate.
Timed Practice & Mock Exams
Timed sessions train you to answer AZ-900 questions confidently and quickly. Full AZ-900 mock exams run at 30 or 60 questions. AZ-900 has a 45-minute time limit with ~40–60 questions — take a 60-question timed mock in your final study days to simulate real conditions.
Crash Mode
AZ-900 is often attempted on a 1–2 week study plan. Crash Mode is built for exactly this: it pulls your missed questions, lowest-accuracy domains, and bookmarked questions into one compressed session. Run it the evening before your exam to close the last gaps.
Missed Questions Review & Bookmarks
Every incorrect answer is saved to Missed Questions Review automatically. Bookmark the Azure service comparisons that confuse you — Functions vs Logic Apps, Blob vs Queue vs Table storage, RBAC vs Azure Policy. Review them before your mock exam without any manual note-taking.
Performance Analytics
Your performance dashboard shows accuracy trends, coverage, and domain performance over time. AZ-900 preparation often compresses into 1–3 weeks — seeing your accuracy improve from 55% to 78% over five days tells you the preparation is working. A flat line tells you to change your approach.
Flashcards & Quick Sessions
AZ-900 flashcards cover Azure service definitions, SLA percentages, pricing tier differences, and compliance certifications — the quick-recall facts AZ-900 tests. Quick 10 lets you drill 10 questions in 5 minutes. Daily Challenge keeps practice consistent if your study plan spans 2+ weeks.
Verdict: The most complete free AZ-900 preparation platform in 2026. Use it from day one through exam morning.
2. Microsoft Learn — Official free assessment
Microsoft's own AZ-900 learning path includes a free practice assessment with ~50 questions. These are the closest to real exam style you will find anywhere.
Pros: Free. Official Microsoft source. Questions match exam style precisely. Cons: Only ~50 questions — not enough volume for full preparation. No domain filtering, no performance tracking, no adaptive practice.
Verdict: Take it at the start to assess your baseline and at the end as a final check. Not a complete study resource on its own.
3. MeasureUp — Official Microsoft practice partner
MeasureUp is Microsoft's official practice test provider for AZ-900, with 150+ questions and an interface that mirrors the real exam.
Pros: Official Microsoft partner. Exam-realistic interface. Good explanations. Cons: ~$99 for a fundamentals exam — expensive. Smaller question pool than Courseiva.
Verdict: Worth it if your employer is paying. If self-funded, Courseiva plus Microsoft Learn's assessment delivers equivalent preparation for free.
4. Whizlabs — Budget paid option
Whizlabs offers 300+ AZ-900 questions at $15–20 with timed exam mode.
Pros: Affordable. Good volume for the price. All domains covered. Cons: Some questions are generic. Explanations can be thin. No adaptive practice or readiness scoring.
Verdict: Acceptable if you want a paid checkpoint. Not necessary given Courseiva's free offering.
5. Scott Duffy Udemy course
Scott Duffy's AZ-900 Udemy course includes practice questions often available at $15–20 during Udemy sales. The video content is clear and the practice questions align well with the exam.
Pros: Clear video instruction. Questions match the exam's conceptual style. Affordable during sales. Cons: Primarily a video course — practice questions are supplementary, not the main product. No adaptive practice or domain proficiency tracking.
Verdict: Good if you prefer video-first learning. Pair with Courseiva for volume and tracking.
How to use Courseiva for AZ-900 prep
Days 1–3: Study Cloud Concepts. Use the AZ-900 domains hub to drill 20 domain-specific questions per session. Read every explanation.
Days 4–6: Move to Azure Architecture and Services. Same approach — 20–30 domain-specific questions. Use your proficiency dashboard to see which service categories are weakest.
Days 7–8: Cover Azure Management and Governance. Policy, cost management, Defender, SLAs.
Final 2 days: Mixed adaptive sessions and a 60-question mock exam. Use Crash Mode the evening before. Aim for 80%+ before sitting.
Frequently asked questions
How hard is AZ-900? Harder than many expect. The exam rewards candidates who understand why Azure services work the way they do — not just their names. Candidates who only memorise service definitions without understanding use cases and trade-offs typically fail.
How many questions does AZ-900 have? AZ-900 has approximately 40–60 questions in a 45-minute exam. Time is not a major constraint — conceptual accuracy is.
Is Courseiva's AZ-900 practice test free? Yes — all questions are free with no account required. A free account unlocks your Exam Readiness Score, domain proficiency tracking, adaptive sessions, and performance analytics.
Verdict
Courseiva is the best free AZ-900 practice test in 2026. Take the Microsoft Learn assessment at the start and end. That combination is all most candidates need to pass first time.
