Find your weak spots

24 questions, about 8 minutes, no timer. Every domain is sampled, weighted the way the real exam weights it. You get a band for each domain and a study-first list, not a pass prediction.

Sample AZ-900 diagnostic questions

These are real items from the AZ-900 bank, one from each of three domains, shown with their answers so you can see the format before you start. The diagnostic itself draws 24 questions from 58 AZ-900 terms , and does not reveal answers until the end.

  1. Azure Management and Governance

    Which best describes “Role-Based Access Control”?

    • · A governance service that enforces organizational rules and evaluates resources for compliance.
    • · Microsoft's cloud identity and access management service, formerly Azure Active Directory.
    • · The all-in cost of running a workload on-premises versus in Azure, compared side by side with the Azure TCO Calculator.
    • ✓ A system that grants users only the permissions they need by assigning roles to scopes.

    Exam tip: RBAC controls who can do what; Azure Policy controls what resources are allowed.

  2. Cloud Concepts

    Which best describes “Elasticity”?

    • · The ability to add or remove resources to match workload demand.
    • ✓ Automatically scaling resources up and down in response to real-time demand.
    • · A computing environment that combines public and private clouds so workloads can move between them.
    • · The ability to restore service and data after a major outage or catastrophic event.

    Exam tip: Elasticity is automatic, dynamic scaling — think autoscale rules.

  3. Azure Architecture and Services

    Which best describes “Azure Region”?

    • · Two Azure regions paired at least 300 miles apart for replication and disaster recovery.
    • ✓ A set of datacenters deployed within a defined geographic area and connected by a low-latency network.
    • · A discrete market, often a country, containing one or more regions for data residency and compliance.
    • · A physically separate datacenter within a region, with independent power, cooling, and networking.

    Exam tip: You pick a region to place resources close to users and meet data-residency rules.

What the AZ-900 diagnostic covers

The quiz mirrors the exam blueprint. Azure Architecture and Services carries the most weight on the real AZ-900, at about 37% of the test, so it gets the most questions here; Cloud Concepts, at about 28%, gets the fewest, but never fewer than 3, because a band should never rest on a single question. The questions draw on the site's AZ-900 term bank, so they measure how well you know the concepts and vocabulary the exam is built on. They are not full-length scenario items.

  1. Azure Architecture and Services

    37% of the exam

    Exam Domains

    Domain 2 — the largest domain: Azure's physical and management infrastructure (regions, availability zones, resource groups, subscriptions) plus core compute, networking, storage, and database services.

    21 terms · 2 study sets

  2. Azure Management and Governance

    35% of the exam

    Exam Domains

    Domain 3 — managing and governing Azure: cost management, governance tools (Policy, Blueprints, locks, tags), monitoring, identity, and the tools used to deploy and manage resources.

    20 terms · 2 study sets

  3. Cloud Concepts

    28% of the exam

    Exam Domains

    Domain 1 — the fundamentals of cloud computing: service models (IaaS, PaaS, SaaS), deployment models, the shared responsibility model, and the benefits of cloud such as scalability and high availability.

How your result is scored

Each domain comes back as a band rather than a percentage: Needs work (under 50% correct), Developing (50% to 79%), or Solid (80% and up). A handful of questions per domain is enough evidence to say "this needs work"; it is not enough to trust a number like 67%, so we do not show one.

The study-first list ranks domains by the share of the exam each one puts at risk: its blueprint weight multiplied by the fraction you missed. On the AZ-900 that maths has teeth, because the domains are not equal — Azure Architecture and Services is worth about 37% and Cloud Concepts about 28%, so half-knowing Azure Architecture and Services costs you roughly 19 points of the exam while barely knowing Cloud Concepts costs about 22. Up to three domains make the list; if all 3 come back Solid, the list is empty and the full-length mock exam is the next real test.

Every question you miss is written into that study set's flashcard deck as due now, so the review queue starts with your actual gaps — across the 2 study sets in Azure Architecture and Services alone, that is the difference between re-reading things you already know and drilling the ones you do not. Your attempts are kept in this browser (the last five), and a retake shows which domains moved up or down since last time.

This is a study map, not a prediction. The real AZ-900 runs 45 questions in 45 minutes and is administered by Microsoft; this is 24 untimed questions drawn from the same blueprint. No sample that short can estimate a result on it, and the site's own mock exam uses a 70% practice target rather than a pass prediction for the same reason.

What to do with your result

  1. Step 1

    Open your first focus domain

    Start with the top of the study-first list. Its study sets are linked right on the results screen; flashcards for the terms you missed are already due.

  2. Step 2

    Drill the set, then quiz it

    Flashcards build recall; the per-set quiz checks it with confusable distractors drawn from related terms.

  3. Step 3

    Retake, then take the mock exam

    After a study block, retake the diagnostic to see which bands moved. When the focus list is empty, the timed AZ-900 mock exam is the next real test.

Frequently asked questions

How long is the AZ-900 diagnostic quiz?
24 questions, untimed. Most people finish in about 8 minutes. Every domain gets at least 3 questions, and the rest are spread in proportion to each domain's weight on the real exam.
Does the result predict whether I will pass?
No. A 24-question sample can tell you which domains need work; it cannot estimate a real AZ-900 result. Treat it as a study map, then measure progress with the full-length mock exam.
Where is my result stored?
In your browser only, using local storage. Nothing is uploaded and no account is needed. Retake the quiz later and the results screen compares the two attempts domain by domain.
What happens to the questions I miss?
Each missed term is scheduled as due in that study set's flashcards, so your next review session starts with exactly the gaps the diagnostic found.
