AZ-900 vs AZ-104: Key Differences for Azure Exam Candidates

AZ-900 is the Azure fundamentals exam, while az-104-exam-and-become-a-microsoft-certified-azure-administrator-associate" data-autoinject="link_injection">AZ-104 serves administrator candidates; both validate Microsoft Azure knowledge but require different approaches.

AZ-900 is the Microsoft Azure Fundamentals exam. It is designed for people who need cloud and Azure literacy, including career changers, managers, sales and procurement stakeholders, junior IT staff, and technical learners who have not yet worked much with Azure. AZ-104 is the Microsoft Azure Administrator exam. It is aimed at candidates who implement, manage, secure, monitor, and troubleshoot Azure resources as part of an administrator or operations role.

Last updated: 2026. Microsoft can revise exam objectives, certification names, and renewal policies, so candidates should verify the current skills measured on Microsoft Learn for Exam AZ-900 and Exam AZ-104 before booking an exam.

The short answer: choose based on hands-on experience

The clearest decision rule is simple: start with AZ-900 if Azure is still mostly theoretical, and consider starting with AZ-104 if Azure administration is already part of daily work. AZ-900 helps a candidate understand cloud concepts, Azure architecture, core services, pricing concepts, governance, and management basics before moving into role-based administration tasks.

AZ-104 becomes the stronger first choice when the candidate already works with identities, resource groups, virtual networks, storage accounts, virtual machines, monitoring, or backup in Azure. In that case, spending weeks on fundamentals may feel too broad, while AZ-104 preparation forces deeper practice with the operational tasks an Azure administrator is expected to perform.

A common misconception is that AZ-900 is a prerequisite for AZ-104, or that either exam is required before higher-level Azure certifications. Microsoft role-based certifications generally do not require formal prerequisite exams. AZ-900 can be skipped when the candidate already has enough cloud and Azure context, although it remains useful for people who want a structured introduction before taking on administrator-level material.

What each exam actually tests

AZ-900 and AZ-104 overlap only at a broad Azure awareness level. AZ-900 asks whether the candidate understands what Azure services are, why cloud models differ, and how management, security, compliance, and cost concepts fit together. It is closer to a literacy exam than an operations exam.

AZ-104 is more practical. It expects knowledge of Microsoft Entra ID, role-based access control, subscriptions, governance, storage, compute, virtual networking, backup, monitoring, and troubleshooting. The candidate is expected to understand how services behave in real administrative scenarios, not merely recognise their names.

When AZ-900 should come first

AZ-900 is the better starting point for candidates who are new to cloud computing, moving from a non-technical role, or supporting Azure-related work without directly administering resources. It gives them the language needed to understand conversations about regions, subscriptions, consumption-based pricing, service models, identity, governance, and basic security.

This route also suits helpdesk staff who are beginning to support cloud users but have not yet configured Azure resources themselves. For instance, a support analyst who handles user access requests may benefit from AZ-900 first because it explains how Microsoft cloud services, identity, and governance fit together before the analyst studies role assignments, policies, network security groups, or diagnostic settings in detail.

AZ-900 can also be useful for managers planning team enablement. It helps non-administrator stakeholders understand the terminology used by engineers and cloud architects, which can improve project conversations. However, hiring teams should not treat AZ-900 as evidence that a candidate can operate Azure infrastructure independently; it is a fundamentals credential, not an administrator credential.

When AZ-104 can come first

AZ-104 can be a sensible first Azure exam for candidates who already work in infrastructure, systems administration, networking, identity, or cloud operations. An on-premises Windows Server administrator who understands Active Directory, DNS, storage, virtual machines, and network segmentation may not need AZ-900 before beginning Azure administrator study, although a quick review of Azure fundamentals can still close vocabulary gaps.

The same applies to professionals already using Azure Portal, PowerShell, Azure CLI, ARM templates, Bicep, or monitoring tools in a live environment. Their main challenge is usually not understanding that cloud services exist; it is learning how Azure implements identity, governance, connectivity, resilience, and diagnostics in ways that differ from traditional infrastructure.

Preparation for AZ-104 should be treated as hands-on work. One frequent mistake is memorising service names while skipping labs, especially around role-based access control, virtual networking, storage access, backup, and monitoring. Practical experience with Microsoft Entra ID, subscriptions, resource groups, network routing, diagnostics, and recovery options is often what separates a candidate who understands the material from one who only recognises it.

How different backgrounds should decide

A career changer with limited IT experience should usually begin with AZ-900, because the exam builds the cloud vocabulary needed to understand later administrator, security, data, or developer paths. Moving straight into AZ-104 without that context can turn preparation into memorisation, which is a weak foundation for later technical work.

A helpdesk technician or junior sysadmin should decide based on daily exposure. If the person has only reset passwords, assigned licences, or supported Microsoft 365 users, AZ-900 is a useful first step. If the person already manages Azure resources, configures access, reviews alerts, or assists with networking and storage, AZ-104 may be the more efficient path.

An experienced on-premises administrator often has enough operational background to start with AZ-104, provided they spend time learning Azure-specific governance and identity models. Traditional infrastructure knowledge transfers well in some areas, but Azure networking, policy, RBAC, managed identities, and monitoring require their own practice.

Cross-functional roles have a different goal. A project manager, service owner, procurement lead, business analyst, or security governance stakeholder may get more value from AZ-900 because it supports better communication with technical teams. AZ-104 is worthwhile only if the role includes actual Azure administration responsibilities or a planned move into operations.

Preparation should match the exam

AZ-900 preparation can be effective with official Microsoft Learn modules, concept notes, service comparisons, short labs, and practice questions that test vocabulary and scenario recognition. Candidates should understand concepts such as public, private, and hybrid cloud; infrastructure as a service, platform as a service, and software as a service; core Azure service categories; shared responsibility; cost management; and governance controls.

AZ-104 preparation needs a different rhythm. Candidates should build and manage resources repeatedly, break configurations safely in a lab, inspect the effect, and then fix them. Identity and governance deserve special attention because they influence nearly every administrator task, from storage access to virtual machine management and monitoring permissions.

Another common pitfall is leaving diagnostics and monitoring until the end. Azure administrators are often judged by their ability to find what changed, identify why access failed, trace network or application symptoms, and restore service. That means logs, alerts, metrics, backup, update management, and resource health should be part of preparation rather than a final revision topic.

Structured training can help when a candidate needs a guided lab sequence and a clear boundary between fundamentals and administrator-level tasks. Readynez can support learners preparing for Microsoft Azure exams, but the choice between AZ-900 and AZ-104 should still be made from role goals and current hands-on exposure rather than from a fixed certification order.

What each certification signals to employers

AZ-900 signals that a candidate understands Azure terminology and cloud operating concepts. That can be valuable for roles where the person collaborates with cloud teams, reviews proposals, supports governance, or needs to interpret Azure discussions without being the person responsible for configuration.

AZ-104 carries a stronger operational signal because it aligns with administrator responsibilities. It suggests that the candidate has studied how to manage identities, compute, storage, networking, and monitoring in Azure. Even so, a certificate should be paired with evidence of practical work, such as lab projects, internal cloud tasks, documentation, troubleshooting examples, or experience supporting production services.

Hiring managers increasingly look for proof that cloud candidates can operate safely. That means understanding least privilege, change control, tagging, monitoring, backup, secure network access, and cost awareness. AZ-104 aligns more closely with those day-to-day expectations, while AZ-900 is better understood as a baseline cloud literacy marker.

Renewal and what to do after the exam

Renewal planning is another reason to understand the difference between the two paths. Microsoft fundamentals certifications such as Azure Fundamentals have historically not required renewal, while role-based associate certifications such as Azure Administrator Associate are subject to Microsoft renewal rules. Candidates should confirm the current policy on Microsoft Learn, especially because renewal windows and assessment requirements can change.

After AZ-900, the next step depends on the role. An administrator path usually leads to AZ-104. A security path may move toward security-focused Microsoft certifications. A data or AI path may move toward Azure data, analytics, or AI credentials. The important point is that AZ-900 does not lock a candidate into one direction; it supplies general cloud context.

After AZ-104, the next move should be based on work responsibilities rather than collecting certifications quickly. An administrator working heavily with security may look at identity and security credentials. Someone involved in architecture may eventually consider architect-level study. A person managing automation, deployment, and platform reliability may need deeper scripting, infrastructure as code, governance, and monitoring practice before adding another exam.

Choosing the first exam with confidence

The best first exam is the one that matches the candidate’s current starting point. AZ-900 is appropriate when the candidate needs cloud vocabulary, Azure context, and a low-risk introduction to Microsoft cloud services. AZ-104 is appropriate when the candidate already has technical foundations and needs to prove administrator-level capability.

The key takeaway is that there is no mandatory order. AZ-900 is helpful, but optional. AZ-104 is more demanding, but realistic as a first Azure exam for candidates with relevant administration experience. Readers who want guided preparation can speak with Readynez about a training route that fits their current Azure exposure and role goals.
