AZ-104 vs AZ-900: Which Azure Exam Should You Take First?

Two of the most commonly discussed Azure certifications are the AZ-900 (Microsoft Azure Fundamentals) and the AZ-104 (Microsoft Azure Administrator). They sit on completely different tiers of the Microsoft certification path, yet candidates frequently ask whether they need both, which to take first, or whether it is safe to skip AZ-900 and go straight to AZ-104. This guide settles those questions by breaking down what each exam actually covers, who it is designed for, how difficult they are relative to each other, and what career signal each credential sends to employers.

What AZ-900 Covers: Azure Fundamentals

The AZ-900 is a conceptual exam. It does not expect you to configure Azure resources, write ARM templates, or manage virtual networks. Instead, it tests whether you understand cloud computing concepts and can describe the purpose and general behavior of Azure services at a high level.

The AZ-900 covers three broad areas: cloud concepts (the benefits of cloud, service models IaaS/PaaS/SaaS, shared responsibility), core Azure services (virtual machines, storage accounts, databases, networking services, and the Azure portal), and Azure management and governance (pricing models, SLAs, cost management tools, Azure Policy, and resource groups). The exam has 40 to 60 questions and a 45-minute time limit, with a passing score of 700 out of 1000.

What AZ-104 Covers: Azure Administrator

The AZ-104 is a hands-on, configuration-level exam. It tests whether you can actually administer Azure infrastructure — deploying and managing virtual machines, configuring virtual networks, implementing storage solutions, managing Azure AD identities, and monitoring Azure resources. This exam assumes you have done these things in Azure, not just read about them.

• Manage Azure identities and governance (15–20%): Azure Active Directory users, groups, and roles; RBAC role assignments; Azure Policy; resource locks; subscriptions and management groups.
• Implement and manage storage (15–20%): Storage accounts and access tiers, blob storage, Azure Files, storage redundancy options (LRS, GRS, ZRS), SAS tokens, and Azure Backup.
• Deploy and manage Azure compute resources (20–25%): VM deployment and configuration, availability sets and zones, VM scale sets, Azure App Service, Azure Container Instances, and Azure Kubernetes Service basics.
• Implement and manage virtual networking (15–20%): VNet creation and subnetting, Network Security Groups, Azure DNS, VNet peering, VPN Gateway, Azure Load Balancer, and Application Gateway.
• Monitor and maintain Azure resources (10–15%): Azure Monitor, Log Analytics, Azure Advisor, Azure Backup and Site Recovery, and update management.

Difficulty Difference: Conceptual vs Hands-On

The difficulty gap between AZ-900 and AZ-104 is substantial. AZ-900 is achievable in one to two weeks of part-time study for someone with a general IT background. The concepts are not deeply technical, and the exam rewards broad awareness rather than precision. Many non-technical professionals in sales, finance, or business analysis pass AZ-900 with minimal cloud background.

AZ-104 is a different experience entirely. Most candidates with active Azure administration experience need 60 to 100 hours of focused preparation. Candidates without hands-on Azure exposure typically need 100 to 140 hours, including significant lab time. AZ-104 questions describe real operational scenarios — choosing between VM sizes for a given workload, selecting the right RBAC role for a specific permission requirement, or deciding which load balancing tier is appropriate for an HTTP versus TCP workload. Answering these correctly requires experience, not just reading.

Should You Skip AZ-900?

If you already work in IT — particularly in infrastructure, networking, or cloud operations — you can almost certainly skip AZ-900 and go directly to AZ-104. The conceptual material covered in AZ-900 will be review for you, and the time spent on a Fundamentals exam is better invested in AZ-104 preparation.

AZ-900 makes sense as a first step if you are: new to cloud computing with no prior IT background, in a non-technical role that requires broad Azure literacy (project management, business development, sales engineering), or if your employer specifically requires it as an entry credential for their certification program. Some organizations use AZ-900 as the baseline for cloud literacy training before employees move to role-based certifications.

Importantly, AZ-900 is not a prerequisite for AZ-104. Microsoft does not require it, and holding AZ-900 does not make you more prepared for AZ-104 in any meaningful way — the overlap in content is minimal. The real prerequisite for AZ-104 is hands-on Azure experience.

Exam Format Differences

AZ-900 contains 40 to 60 questions in a 45-minute window. Question types are straightforward: multiple choice, drag-and-drop ordering, and matching questions. There are no case study questions and no lab-based simulations. The passing score is 700 out of 1000.

AZ-104 contains 40 to 60 questions across a 120-minute window, which includes case study questions — multi-page scenarios followed by several questions drawing on the same scenario. Case studies slow candidates down significantly because you must absorb a large amount of context before answering. AZ-104 may also include performance-based questions that require you to complete a task directly within an Azure simulation environment, not just select an answer. The passing score is also 700 out of 1000.

Career Implications: What Each Credential Signals

AZ-900 signals basic cloud awareness. It rarely appears as a requirement in technical job postings, and it is not a differentiator in Azure engineer or administrator hiring. It is valuable for demonstrating Azure familiarity in roles where cloud is one of many responsibilities, or as evidence of a formal cloud learning program.

AZ-104 is a genuine hiring signal. It appears in job requirements for cloud administrator, Azure infrastructure engineer, and cloud operations roles. It demonstrates that you can manage Azure resources independently, which is what employers hiring for those roles need to verify. Holding AZ-104 also serves as the foundation for the Azure Solutions Architect Expert path (AZ-305) and the Azure Security Engineer Associate path (AZ-500), both of which carry significant market value.

Preparing for Either Exam with Certify Copilot

Whether you are working through AZ-900 conceptual questions or drilling AZ-104 scenario-based problems, Certify Copilot provides AI-powered practice questions aligned to both exams. For AZ-900, the explanations help you build clear conceptual understanding of Azure service categories, pricing models, and governance features. For AZ-104, the practice questions cover the hands-on administrative scenarios — RBAC assignments, VNet configuration decisions, storage redundancy selection — that define the real exam experience. Starting with targeted practice early in your preparation is the fastest path to consistently passing both exams.
