AZ-104 vs AZ-900 – take AZ-900 first if you are new to cloud computing, then move to AZ-104. Skip AZ-900 and go directly to AZ-104 if you already have hands-on Azure experience, a systems administration background, or an equivalent cloud certification like AWS Solutions Architect. AZ-900 is not a prerequisite for AZ-104 – but 60 to 70 percent of candidates who fail AZ-104 on their first attempt skipped AZ-900.
The question is not which certification is better. The question is which one is right for your current situation.

What Is the Main Difference Between AZ-900 and AZ-104?
The main difference between AZ-900 and AZ-104 is that AZ-900 tests what you know about Azure and AZ-104 tests what you can do in Azure. AZ-900 is a literacy exam – it validates that you can speak intelligently about cloud concepts, Azure services, pricing, and governance. AZ-104 is a skills exam – it validates that you can configure virtual networks, manage storage accounts, implement security policies, and troubleshoot live Azure environments.
AZ-900 asks: “What is an Azure Virtual Network?” AZ-104 asks: “Configure a Virtual Network with three subnets, apply a Network Security Group, and restrict traffic between them.”
That difference defines everything – difficulty, study time, job impact, and salary.
Should You Take AZ-900 Before AZ-104?
You should take AZ-900 before AZ-104 if you are new to cloud computing. You should skip AZ-900 and go directly to AZ-104 if you have hands-on Azure or cloud experience. There is no wrong answer – the right answer depends entirely on your background.
Take AZ-900 First If:
You are completely new to cloud computing. AZ-900 teaches the vocabulary and concepts – IaaS, PaaS, SaaS, regions, availability zones, RBAC, resource groups – that AZ-104 assumes you already know. Entering AZ-104 without this foundation means learning two exams simultaneously, which significantly increases study time and failure risk.
You are switching careers from a non-IT field. AZ-900 provides the conceptual grounding that makes AZ-104’s technical content significantly more approachable. Candidates who take AZ-900 first typically need 6 to 8 weeks for AZ-104. Candidates who skip it need 10 to 14 weeks.
You want a confidence-building win first. AZ-900 takes 2 to 4 weeks to prepare for, costs $165, and never expires. Passing it gives you a verified Microsoft credential on your transcript immediately while you prepare for the significantly more demanding AZ-104.
You work in a non-technical role. Sales engineers, project managers, business analysts, and consultants who need Azure fluency without deep technical implementation skills get strong value from AZ-900 as a standalone credential.
Skip AZ-900 and Go Directly to AZ-104 If:
You already work with Azure regularly. If you navigate the Azure Portal daily, have configured virtual machines, managed storage accounts, or worked with Azure networking, you already know what AZ-900 tests. Skip it and invest your time in AZ-104 preparation.
You hold an equivalent cloud certification. AWS Solutions Architect Associate, Google Associate Cloud Engineer, or CompTIA Cloud+ holders already understand cloud concepts at a level that makes AZ-900 redundant. Go directly to AZ-104 and focus on Azure-specific implementation details.
You have 6 or more months of systems administration experience. Windows Server admins, network engineers, and virtualization specialists who understand Active Directory, networking fundamentals, and storage concepts have the background that AZ-900 covers. They can go directly to AZ-104 and typically pass in 6 to 8 weeks.
Your employer requires AZ-104 urgently. If a job offer or promotion depends on AZ-104 within the next 8 to 10 weeks, you cannot afford the time for AZ-900 first. Focus all preparation on AZ-104 directly and budget 10 to 14 weeks of study time.
AZ-900 vs AZ-104: Difficulty Comparison
AZ-104 is significantly harder than AZ-900. It is not just a harder version of the same exam – it is a fundamentally different type of exam that tests a completely different category of skills.
| Factor | AZ-900 | AZ-104 |
| Question type | Multiple choice, conceptual scenarios | Multiple choice, case studies, live lab simulations |
| Hands-on portal required | No | Yes – you configure real Azure resources during the exam |
| CLI knowledge required | No | Yes – PowerShell and Azure CLI commands are tested |
| Pass rate | 75 to 85% for prepared candidates | 60 to 70% for prepared candidates |
| Most common failure reason | Underestimating governance domain | Insufficient hands-on lab practice |
| Preparation approach | Study concepts and read | Study concepts AND build in Azure Portal daily |
The lab simulation warning: AZ-104 includes live lab simulations where you configure actual Azure resources in a real portal environment during the exam. Reading about virtual networks is not sufficient preparation for this. Candidates who study theory without building real Azure environments consistently fail the lab section. Microsoft offers a free Azure account with $200 in credits – use it from day one of your AZ-104 preparation.
AZ-900 vs AZ-104: Salary Comparison
| Certification | Entry Salary US | Average Salary US | Senior Salary US |
| AZ-900 alone | $55,000 to $70,000 | $65,000 to $80,000 | $80,000 to $95,000 |
| AZ-104 | $85,000 to $100,000 | $100,000 to $120,000 | $120,000 to $145,000 |
| AZ-900 plus AZ-104 | $85,000 to $100,000 | $105,000 to $125,000 | $125,000 to $150,000 |
The honest salary truth: AZ-900 alone does not produce significant salary jumps for technical roles. Employers hiring Azure administrators, cloud engineers, and infrastructure specialists want AZ-104. AZ-900 alone typically adds $5,000 to $8,000 to an existing IT salary. AZ-104 adds $15,000 to $30,000 and opens roles that AZ-900 alone cannot reach.
If your goal is a six-figure cloud salary, AZ-900 is the starting block, not the finish line. AZ-104 is where the income transformation happens. For the complete salary and career analysis of AZ-104 as a standalone credential, our Is AZ-104 Worth It guide covers every detail.
What Does AZ-900 Cover vs AZ-104?
AZ-900 Exam Domains
| Domain | Weight | What You Learn |
| Cloud concepts | 25-30% | IaaS vs PaaS vs SaaS, CapEx vs OpEx, cloud models, consumption-based pricing, scalability, high availability |
| Azure architecture and services | 35-40% | Regions, availability zones, resource groups, subscriptions, VMs, App Service, storage types, databases, networking concepts, Azure AI services |
| Azure management and governance | 30-35% | Azure Cost Management, Azure Policy, RBAC, Azure Blueprints, Microsoft Purview, Azure Monitor, Service Trust Portal |
AZ-104 Exam Domains
| Domain | Weight | What You Do |
| Manage Azure identities and governance | 15-20% | Configure Microsoft Entra ID, manage users and groups, implement RBAC, manage subscriptions, Azure Policy, resource locks |
| Implement and manage storage | 15-20% | Configure storage accounts, manage blob storage, Azure Files, storage redundancy, lifecycle policies, Azure Storage Explorer |
| Deploy and manage Azure compute resources | 20-25% | Deploy VMs, configure VM scale sets, manage Azure App Service, Azure Container Instances, Azure Kubernetes Service basics |
| Implement and manage virtual networking | 15-20% | Configure VNets, subnets, NSGs, Azure DNS, VPN Gateways, ExpressRoute, Azure Load Balancer, Azure Application Gateway |
| Monitor and maintain Azure resources | 10-15% | Azure Monitor, Log Analytics, Azure Alerts, Azure Backup, Azure Site Recovery, Azure Update Manager |
35 percent of AZ-900 content overlaps with AZ-104 at a surface level. The services are the same – VMs, storage, networking, Azure AD – but AZ-104 goes from “what is it” to “configure it, secure it, troubleshoot it, and optimize it.” This overlap is exactly why AZ-900 accelerates AZ-104 preparation without making it redundant.
How Long Does Each Certification Take?
| Scenario | AZ-900 Study Time | AZ-104 Study Time After AZ-900 | Total Time |
| Complete beginner to cloud | 3 to 4 weeks | 8 to 10 weeks | 11 to 14 weeks |
| Some IT experience, no Azure | 2 to 3 weeks | 6 to 8 weeks | 8 to 11 weeks |
| IT professional with Azure exposure | 1 to 2 weeks | 4 to 6 weeks | 5 to 8 weeks |
| Skipping AZ-900, starting at AZ-104 | Not applicable | 10 to 14 weeks | 10 to 14 weeks |
The time math: Taking AZ-900 first adds 2 to 4 weeks to your total timeline compared to skipping it – but it reduces AZ-104 study time by 4 to 6 weeks. For most beginners, taking AZ-900 first results in a shorter total timeline and a significantly higher first-attempt pass rate on AZ-104.
AZ-900 vs AZ-104: Which Gets You Hired Faster?
| Job Goal | Fastest Path |
| First IT job with no experience | AZ-900 now, AZ-104 in 3 months |
| Azure Administrator role | Skip AZ-900, go directly to AZ-104 |
| Cloud support specialist | AZ-900 is sufficient as a starting point |
| Cloud engineer or infrastructure engineer | AZ-104 required – AZ-900 alone will not qualify |
| Sales or pre-sales engineer | AZ-900 alone is often sufficient |
| Project manager working with Azure teams | AZ-900 alone is sufficient |
| Moving into Azure architecture eventually | AZ-900 then AZ-104 then AZ-305 |
AZ-104 is the minimum technical credential for Azure Administrator, Cloud Engineer, and Infrastructure Engineer roles. AZ-900 alone will not get you hired for these positions. For the full career path from AZ-900 through AZ-104 to expert level, our IT certification roadmap covers every step.
Can You Take AZ-104 Without AZ-900?
Yes. Microsoft does not require AZ-900 as a prerequisite for AZ-104. You can register for and take AZ-104 without ever having taken AZ-900. There is no formal gate between them.
However, data consistently shows that candidates who skip AZ-900 with no equivalent background knowledge fail AZ-104 at significantly higher rates. The exam assumes foundational cloud literacy. Candidates who lack it spend the first third of their AZ-104 preparation building the foundation that AZ-900 would have given them in 2 to 3 weeks for $165.
The practical rule: If you can answer these five questions confidently without studying, skip AZ-900 and go directly to AZ-104.
- What is the difference between IaaS, PaaS, and SaaS?
- What is an Azure region and an availability zone?
- What is RBAC and how does it work in Azure?
- What is the difference between Azure Policy and RBAC?
- What is a resource group and why does it matter?
If you hesitated on any of these, take AZ-900 first. If you answered all five immediately and confidently, go to AZ-104.
The Optimal Path: AZ-900 to AZ-104 to AZ-305
For most professionals building a cloud career from scratch, the highest-ROI Azure certification sequence is:
Step 1: AZ-900 – 2 to 3 weeks – builds foundation, earns a never-expiring credential, makes AZ-104 faster
Step 2: AZ-104 – 6 to 8 weeks – the real career accelerator, opens $100,000 to $130,000 roles
Step 3: AZ-305 – 8 to 12 weeks – expert level, requires AZ-104, opens $130,000 to $170,000 architect roles
This three-certification sequence takes most candidates 6 to 9 months of part-time study. It is the most direct path from zero to a six-figure Azure career. Our Is AZ-900 Worth It guide covers the first step in detail. For the complete picture of all Azure and Microsoft certifications including the 2026 changes, our Microsoft certifications retiring in 2026 guide covers every current path.
How to Prepare for AZ-900
Step 1: Complete the free Microsoft Learn AZ-900 path. Every exam objective is covered in free official modules with knowledge checks. This is sufficient for most candidates with some IT background.
Step 2: Watch John Savill’s free AZ-900 study cram on YouTube. The most recommended single-video resource for AZ-900 – covers all content in approximately 3 hours.
Step 3: Take practice exams until scoring 80 percent consistently. Practice questions identify gaps before exam day does. Our AZ-900 exam preparation materials are aligned to the current 2026 blueprint including AI and governance content.
Step 4: Book your exam date before you feel completely ready. Candidates with a deadline study more efficiently. Set your exam 3 to 4 weeks from when you start.
How to Prepare for AZ-104
Step 1: Build everything in the Azure Portal from day one. AZ-104 has live lab simulations. You must have genuine hands-on experience. Create a free Azure account and deploy real resources starting in week one of your preparation – not week six.
Step 2: Learn PowerShell and Azure CLI for key tasks. CLI commands appear in AZ-104 questions. You do not need to memorize every parameter but you must recognize correct command syntax for common tasks like creating VMs, configuring NSGs, and managing storage.
Step 3: Focus extra time on networking. Virtual networks, subnets, NSGs, VPN Gateways, peering, and DNS are consistently the most heavily tested and most commonly failed areas of AZ-104. Build multiple VNet configurations hands-on.
Step 4: Take full practice exams under timed conditions. AZ-104 is 120 minutes and tests a wide range of topics. Time management matters. Practice under exam conditions before test day. Our Microsoft exam preparation section covers current AZ-104 practice materials.
