Q: How long is the AZ-900 exam, and how many questions should I expect?

You get 45 minutes of actual exam time for AZ-900, and most Microsoft certification exams contain between 40 and 60 questions . That works out to roughly a minute or less per question, so practice answering quickly and flag anything you want to revisit rather than getting stuck. Your total seat time is 65 minutes — the extra time covers things like the non-disclosure agreement and exam instructions, so it isn't additional answering time. Five minutes are also built into the exam time that you can use for an unscheduled break if you need one.

Q: What score do I need to pass AZ-900, and should I guess on questions I don't know?

You need a score of 700 or greater to pass. Microsoft reports technical exam scores on a scale of 1 to 1,000 — so 700 is a scaled score, not a simple percentage of questions answered correctly. Always answer every question. There is no penalty for guessing — no points are deducted for incorrect answers — so a blank question can only cost you points, while an educated guess can only help.

Q: What topics are on the AZ-900 exam, and which area should I study most?

AZ-900 assesses foundational knowledge across three domains , each with a published weight: Describe cloud concepts (25–30%) — cloud computing, the shared responsibility model, cloud models, the consumption-based model, the benefits of cloud services, and the IaaS, PaaS, and SaaS service types. Describe Azure architecture and services (35–40%) — core architectural components, Azure compute and networking services, Azure storage services, and Azure identity, access, and security. Describe Azure management and governance (30–35%) — cost management, governance and compliance features, tools for managing and deploying resources, and monitoring tools. Architecture and services carries the heaviest weight at 35–40%, so it deserves the largest share of your study time — it's also the domain with the widest spread of individual Azure services to learn.

Question 4

What happens if I fail AZ-900 — how soon can I retake it?

Accepted Answer

Failing isn't the end of the road, and the first retake comes quickly: if you don't pass on your first attempt, you can retake the exam after a 24-hour wait.

After that, the policy tightens: a 14-day waiting period applies between all subsequent attempts, and you may not take a given exam more than five times within a 12-month period from your first attempt. Practically, that means your second attempt is cheap in time, but from the third attempt onward each try costs you at least two weeks — so use the wait to close the specific gaps your score report reveals rather than rushing back in.
