Microsoft Azure Fundamentals (AZ-900): What's Actually Tested

Microsoft Azure Fundamentals (AZ-900) is the on-ramp to every other Azure certification and the credential most often listed as "nice to have" in cloud-adjacent job postings. The exam is $99, runs 45 minutes, has roughly 40 to 60 questions, and requires 700 out of 1000 to pass. Most candidates need 2 to 4 weeks of light study. The questions test whether you can describe Azure concepts, not configure them, which makes AZ-900 the easiest real certification in the Microsoft catalog. If you work in IT in any capacity, you can pass this with a couple of weekends of focused reading.

The 90-second answer

Take AZ-900 if you're new to cloud, you're about to start an Azure role, or you need a recognizable credential to put on a resume while you study for something harder. It's also the right pick if your employer is moving to Azure and you want shared vocabulary with the people who run it. At $99 and a 45-minute sitting, the cost-to-credibility ratio is excellent.

Skip AZ-900 if you already have hands-on Azure experience and you're aiming for an admin or engineering role. In that case go straight to AZ-104 (Azure Administrator). AZ-900 is a knowledge check, not a skills check, so experienced practitioners often find it too shallow to bother with on its own.

What does the AZ-900 actually test?

AZ-900 tests three domains. Microsoft refreshed the objectives on January 14, 2026, but only with minor wording changes. The weights below are the current published ranges. Every question maps to one of these.

Domain	Weight	What it covers
Describe cloud concepts	25-30%	Cloud computing, shared responsibility model, public/private/hybrid, IaaS/PaaS/SaaS, consumption-based pricing, serverless
Describe Azure architecture and services	35-40%	Regions, availability zones, resource groups, subscriptions, management groups, VMs, networking, storage, Entra ID, RBAC, Zero Trust
Describe Azure management and governance	30-35%	Cost management, tags, Azure Policy, resource locks, Azure portal, Cloud Shell, Azure Monitor, Advisor, Service Health

Notice the word "describe" in every domain title. That's deliberate. You are never asked to build a virtual network or write a policy. You're asked which service solves a stated problem, what the shared responsibility model means, or why you'd use a resource lock. It is recognition and recall, not configuration.

The architecture and services domain is the largest at 35 to 40%, so that's where your study time should concentrate. Most people lose points there by confusing similar services: Entra ID versus Entra Domain Services, availability zones versus region pairs, or which storage redundancy option survives a regional outage.

How hard is the AZ-900?

AZ-900 is a difficulty 1 out of 5. It is the gentlest paid certification Microsoft offers. There is no scenario you have to architect, no command syntax to memorize, and no time pressure worth worrying about: 45 minutes for 40 to 60 questions is comfortable.

The exam is genuinely fair, but a few things still trip people up:

• Marketing-sounding answer choices that all "sound right" until you know the exact service definitions
• Microsoft renaming things (Azure Active Directory became Microsoft Entra ID, and older study material still uses the old name)
• Drag-and-drop and "select all that apply" questions where you need the complete set, not just one correct item
• Governance terms that blur together (Azure Policy, resource locks, management groups, and tags all sound like cost or compliance tools)

People who fail AZ-900 almost always studied from outdated free dumps with wrong service names, or they skipped the management and governance domain because it sounded boring. That domain is 30 to 35% of the exam. You cannot afford to skip a third of the test.

How long should you study for AZ-900?

Microsoft positions AZ-900 as having no prerequisites and no required experience. The study time depends entirely on your starting point:

• Working in IT already (any stack): 1 to 2 weeks at 5 to 6 hours per week
• New to cloud but technically literate: 3 to 4 weeks at 5 to 6 hours per week
• Complete beginner, non-technical background: 4 to 6 weeks at 4 to 5 hours per week
• Already using Azure at work: a few days of review to map your hands-on knowledge to the exam's vocabulary

The most efficient path is Microsoft's own free Learn modules, because the exam questions are written from the same source material. Create a free Azure account and click through the portal while you read. Seeing a resource group, a storage account, and the pricing calculator in the actual portal makes the abstract terms stick far faster than video courses do.

A realistic week-by-week pace for a 3-week study plan looks like:

1. Week 1: Cloud concepts (IaaS/PaaS/SaaS, public/private/hybrid, shared responsibility, consumption pricing, serverless)
2. Week 2: Azure architecture (regions, availability zones, resource groups, subscriptions, VMs, virtual networks, storage tiers and redundancy, Entra ID and RBAC)
3. Week 3: Management and governance (cost management, tags, Azure Policy, resource locks, the portal, Cloud Shell, Azure Monitor and Advisor), plus practice questions and the free Microsoft practice assessment

Take the official free practice assessment on Microsoft Learn at least once before exam day. If you score above 80% on it cold, you're ready.

What does the AZ-900 cost?

The exam itself is $99 USD plus any local taxes. Total cost stays low because the best resources are free:

Component	Range	Notes
Exam fee	$99	One attempt. Retake is another $99 if you fail.
Microsoft Learn modules	$0	Official free training, same source as the exam
Practice questions	$0 to $30	NerdExam has 332 AZ-900 questions if you want a free option
Azure free account	$0	Free tier plus $200 credit for the first 30 days
Official practice assessment	$0	Free on Microsoft Learn, mirrors the real exam style
Total realistic spend	$99 to $130	Cheapest viable path: $99 (exam only)

Microsoft regularly runs free AZ-900 voucher campaigns tied to Virtual Training Days. If you attend one of those free online events, you often receive a 100% exam voucher afterward, which drops your total cost to zero. Check the Microsoft Events page before you pay full price.

What salary can you expect?

AZ-900 is a foundational cert, so be honest about what it does. It rarely lands a job on its own, but it signals cloud literacy and is a real resume line for career changers. US salary data for 2026 shows a wide range that reflects how varied the roles are:

• Entry-level cloud-adjacent roles with AZ-900: $65,000 to $90,000
• Average across all "Azure Fundamentals" titled roles: $110,000 to $120,000 (skewed by experienced people who happen to hold it)
• Typical bump from adding AZ-900 to an existing IT salary: $5,000 to $8,000
• With AZ-900 plus AZ-104 and real Azure work: $120,000 to $140,000

The honest read: AZ-900 by itself is worth a few thousand dollars and a foot in the door, not a six-figure jump. The real money comes from the role-based certs it leads to (AZ-104, AZ-204, AZ-305) paired with hands-on experience. Treat AZ-900 as the cheapest way to prove you're serious about cloud, then keep going.

What study resources actually work?

The candidates who pass on the first attempt keep it simple:

1. Microsoft Learn AZ-900 learning path (free). It's the primary source the exam is written from. Do not skip the management and governance modules.
2. A free Azure account so you can click through the portal, the pricing calculator, and a sample resource group while you read
3. The official Microsoft practice assessment (free), taken at least twice in your final week
4. John Savill's AZ-900 study cram on YouTube (free), a single recorded session that condenses the whole syllabus for review
5. At least 200 practice questions to confirm you recognize service names and definitions under exam phrasing

Be careful with free "dump" sites. Many use outdated service names (Azure Active Directory instead of Microsoft Entra ID) and have wrong answers that teach you the test incorrectly. Stick to current sources.

For the practice question portion, NerdExam has 332 enriched AZ-900 questions with full explanations. Start practicing AZ-900 questions to see the exact "describe the service" phrasing before exam day. The free explanations walk through why each distractor is wrong, which is the fastest way to stop confusing similar Azure services.

Who should NOT take AZ-900?

The cert is the wrong move for these candidates:

You are	Take instead
An experienced Azure admin	AZ-104 (Azure Administrator Associate)
A developer building on Azure	AZ-204 (Azure Developer Associate)
Targeting a solutions architect role	AZ-305, after AZ-104
A data or AI professional	DP-900 or AI-900 (the matching fundamentals tracks)
Working primarily in AWS or GCP	AWS Cloud Practitioner (CLF-C02) or Google Cloud Digital Leader. Match the cert to your stack.

The only real mistake with AZ-900 is over-investing in it. It's a two-to-four-week credential, not a multi-month project. If you find yourself studying it for two months, you're either using bad materials or you should have started on a role-based cert.

What's next after AZ-900?

AZ-900 is a launching pad, and three paths open up depending on your role:

• Administrator track: AZ-104 (Azure Administrator Associate). The most common next step and the one most job postings actually require. Expect a real jump in difficulty: AZ-104 is hands-on and config-heavy.
• Developer track: AZ-204 (Azure Developer Associate), for engineers who build and deploy applications on Azure.
• Other fundamentals: DP-900 (Data), AI-900 (AI), or SC-900 (Security). These are sibling exams at the same easy level, and stacking two or three fundamentals signals broad cloud literacy cheaply.

Most people move from AZ-900 to AZ-104 within 3 to 6 months. Use that window to get real hands-on time in the Azure portal, because every cert above the fundamentals level assumes you've actually built things, not just read about them.
