AZ-104 vs AZ-204: Azure Administrator vs Developer Associate Compared

2026-05-24
NicheeLab Editorial Team

AZ-104 (Azure Administrator Associate) and AZ-204 (Azure Developer Associate) have long stood as the twin pillars of the Azure Associate tier. Both share the same headline specs — USD 165, 100-120 minutes, 40-60 questions, 700 to pass — yet the target roles and exam content are distinctly different. This article compares the two from multiple angles to help you decide which to take, and whether taking both is worth it. We also factor in the latest options after AZ-204's retirement on July 31, 2026.

Target Role Differences

The single biggest thing that separates AZ-104 and AZ-204 is who the exam is for.AZ-104 targets people who operate and manage Azure environments and tests skills for configuring and running VMs, VNets, Storage, Backup, and Monitor using the Azure portal, Azure CLI, PowerShell, and Bicep.AZ-204 targets people who build applications on Azure and tests skills for working with App Service, Functions, Cosmos DB SDK, Service Bus, API Management, and Event Grid from C#, Python, JavaScript, or Java code.

This difference shows up directly in question style. AZ-104 leans heavily on operations-style questions such as "how do you configure this setting in the Azure portal?" or "which CLI command option is correct?", while AZ-204 is dominated by code-reading questions such as "what is the return value of this C# / Python code?" or "how do you optimize this Cosmos DB SDK query?".

Scope Overlap and Unique Areas

The exam scopes overlap by roughly 30-40%. Shared areas include identity (Entra ID authentication, Managed Identity, OAuth 2.0), Storage SDK / Blob operations, networking basics (VNet, NSG, Private Endpoint), monitoring (Azure Monitor, Application Insights), and IaC (ARM, Bicep). If you take AZ-104 first and then move on to AZ-204, you can usually cover these areas with little to no additional study.

The unique areas are cleanly separated.AZ-104 only: VMSS scaling, Azure Backup / Site Recovery, Azure Files (SMB/NFS), Storage account replication (LRS/GRS, etc.), VPN Gateway / ExpressRoute, Application Gateway / Load Balancer, basic KQL, Azure Policy / RBAC / Resource Lock.AZ-204 only: App Service Deployment Slots, every Functions trigger type (Timer/Blob/Queue/HTTP/Event Hub/Service Bus/Cosmos DB), Cosmos DB SDK partition design and query optimization, Service Bus FIFO / sessions / transactions, API Management policies, Event Grid schema and webhook delivery, Container Apps scaling rules, and OpenAPI / Swagger knowledge.

Difficulty and Study-Time Comparison

Study time tends to be longer for AZ-204. For AZ-104, Japanese candidate reports average 100-150 hours for those with 1-3 years of IT experience, 60-100 hours if you already know another cloud, and 150-200 hours for IT generalists who are new to Azure. For AZ-204, the typical ranges are 100-150 hours for developers with 3+ years of app experience, 150-250 hours for Azure-savvy candidates whose dev experience is lighter, and 300+ hours for total beginners.

AZ-204 takes longer because it assumes you can already code. Candidates without programming fundamentals need to add 50-100 hours of upfront language study in Python, C#, or JavaScript. On the other hand, experienced developers sometimes find AZ-104 takes longer than AZ-204 because they have little hands-on experience with infrastructure tasks like VM sizing, picking a storage replication tier, or configuring VPNs.

The AZ-204 Retirement and What It Means for Your Choice

In January 2026, Microsoft announced the retirement of AZ-204 on July 31, 2026. As of this article's publication, no successor exam has been announced, and Microsoft Learn does not yet publish a clear successor roadmap. That makes any decision to take AZ-204 as a new candidate a strategic one.

There are three realistic options:

  • Option A (last-minute attempt): Pass AZ-204 by July 2026. A pass is valid for 12 months, giving you time to wait for the successor exam. Best for people whose study is already well underway.
  • Option B (substitute with AZ-104): Skip AZ-204, earn AZ-104, and wait for the successor announcement. The safest choice for new learners.
  • Option C (pivot to a new area): Skip AZ-204 and move on to AI-103 (GA in June 2026) or AZ-400 (DevOps). Best for engineers interested in AI or DevOps.

There is no guarantee that Microsoft will release a direct successor in the same "Azure Developer Associate" slot, and some observers expect the developer role to fragment across AI-103 (AI development) and AZ-400 (DevOps Expert). For more, see the AZ-204 complete guide.

How to Choose: Recommended Paths

Here are our recommendations:

  • Infrastructure engineer / SRE / operations: AZ-104 only. No need for AZ-204.
  • App developer / backend engineer (already on Azure): Take AZ-204 before June 2026, and start planning a move to AI-103 (GA 2026-06) or AZ-400 in parallel.
  • App developer / backend engineer (just starting): Skip AZ-204 and take the safer AZ-104 → AI-103 or AZ-400 path.
  • Aspiring DevOps engineer / full-stack: The triple AZ-104 → AZ-204 (last-minute) → AZ-400 is the strongest play.
  • Cloud beginner (role not yet decided): Start with AZ-900 → AZ-104 to get a feel for cloud as a whole, then branch into AZ-204 or another Associate depending on what interests you.

If You're Taking Both: Study Order

If you want both, AZ-104 → AZ-204 is the standard order. The Entra ID, Storage, VNet, and Monitor fundamentals you pick up for AZ-104 transfer directly into AZ-204, cutting roughly 30-50 hours off the standalone AZ-204 study time. The reverse order (AZ-204 → AZ-104) is inefficient because AZ-104 then piles on a large block of infrastructure-ops content — VMs, VPNs, Backup, Site Recovery — that AZ-204 never touches. Plan on a combined 200-300 hours if you have prior experience, or 400+ hours if you're starting from zero.

What to Earn Next

After AZ-104 and AZ-204, several paths open up.Solutions Architect Expert: AZ-305 covers Expert-tier design decisions. AZ-104 holders already meet the AZ-305 prerequisite, so AZ-104 + AZ-305 alone reaches Expert.DevOps Engineer Expert: AZ-400 covers CI/CD, IaC, GitOps, and SRE practices. Either AZ-104 or AZ-204 satisfies its prerequisite, so AZ-104 + AZ-400 or AZ-204 + AZ-400 reaches Expert.Network Engineer Associate: AZ-700 goes deeper on networking specialization.Security track: SC-300 (Identity Admin), SC-200 (SOC Analyst), and SC-500 (the former AZ-500, GA 2026-09).AI / Data track: AI-103 (GA 2026-06), DP-700, and DP-300.

Frequently Asked Questions

What is the biggest difference between AZ-104 and AZ-204?

They target different roles. AZ-104 (Azure Administrator) is for people who operate and manage Azure environments — administrators who configure infrastructure resources such as VMs, VNets, Storage, and Backup via the Azure portal, Azure CLI, PowerShell, and Bicep. AZ-204 (Azure Developer) is for people who build applications on Azure — developers who call App Service, Functions, Cosmos DB SDK, Service Bus, and similar services from code (C#, Python, JavaScript, or Java). AZ-104 leans toward infrastructure while AZ-204 leans toward application code, and that distinction shows up in the question style too: AZ-104 emphasizes portal operations and configuration choices, while AZ-204 is centered on reading code snippets.

Which one should I take first?

It depends on your background. Infrastructure engineers, SREs, and operations staff should take AZ-104 first. Application developers and backend engineers used to take AZ-204 first, but AZ-204 is scheduled to retire on July 31, 2026 with no successor announced, so any new attempt needs careful consideration. If cloud is brand new to you, AZ-104 is the safer choice — it has the broadest learning content and the most transferable hands-on practice. If you want both certifications, the standard order is AZ-104 → AZ-204, since the ID, Storage, and Network basics you learn for AZ-104 carry directly into AZ-204.

Has the AZ-204 retirement changed the value of AZ-104?

AZ-104's market value has actually gone up in relative terms. With AZ-204 retiring and the Azure developer Associate slot left empty for a while, AZ-104 remains the de facto must-have certification for the Azure Associate tier. It is still the foundation for every step toward Expert or specialty Associate certifications — Azure Architect (AZ-305), DevOps (AZ-400), Network (AZ-700), Security (SC-500) — and job postings that say 'AZ-104 required' or 'AZ-104 preferred' vastly outnumber those that mention AZ-204. Indirectly, the AZ-204 retirement is normalizing the path where developers take AZ-104 first and then move on to AI-103 or AZ-400.

Which exam takes longer to study for?

It depends on your background, but AZ-204 generally takes longer. AZ-104 averages 100-150 hours for someone with 1-3 years of IT experience, 60-100 hours for those with experience on another cloud, and 150-200 hours for IT generalists new to Azure. AZ-204 takes 100-150 hours for developers with 3+ years of experience, 150-250 hours for those who know Azure but have less coding experience, and 300+ hours for total beginners. Because AZ-204 assumes you can write code, candidates without programming fundamentals see study time balloon. Plan for a combined 200-400 hours if you want both certifications.

How much do the exam scopes overlap?

Roughly 30-40% overlap. Shared areas include identity (Entra ID authentication, Managed Identity, OAuth 2.0), Storage SDK and Blob operations, networking basics (VNet, NSG, Private Endpoint), monitoring (Azure Monitor, Application Insights), and IaC (ARM, Bicep). What you learn for AZ-104 in these areas applies directly to AZ-204. The non-overlapping parts are clearly different. AZ-104 only: VMSS, Backup, Site Recovery, Azure Files, detailed Storage account settings, VPN, ExpressRoute, Application Gateway, and Load Balancer. AZ-204 only: code-centric topics like App Service Deployment Slots, the full set of Functions triggers, Cosmos DB SDK patterns, Service Bus messaging, API Management, Event Grid, and Container Apps scaling rules.

Is it worth taking both?

Yes, if you are aiming at DevOps, full-stack, or SRE roles. Engineers who can speak both the infrastructure and application sides are perpetually in short supply, and the AZ-104 + AZ-204 + AZ-400 (DevOps Engineer Expert) trio is a strong weapon for DevOps roles in the JPY 8M-12M salary band. If you're going pure infra ops or pure app development, the realistic post-AZ-204-retirement paths are AZ-104 alone plus AZ-305 (Architect), or AZ-104 plus language-specific skills plus AI-103 (GA in 2026-06). Any decision to rush AZ-204 before the July 2026 deadline should be made with a clear eye on ROI.

Are the exam fees the same?

Yes — both are Associate-tier exams priced at USD 165 / JPY 21,103 (tax included), valid for 12 months, with credit-card payment through Pearson VUE as the standard. Neither offers a direct Virtual Training Day voucher perk, but because AZ-104 has a larger learner population, free voucher campaigns tied to Microsoft Reactor hands-on events and the Cloud Skills Challenge run more often for AZ-104 than for AZ-204. After the retirement announcement, free and discounted voucher campaigns for AZ-204 have visibly shrunk in 2026.

What's the next step after passing both?

DevOps Engineer (AZ-400) and Solutions Architect (AZ-305) are the standard next steps. AZ-104 + AZ-204 + AZ-400 gives you full-cycle DevOps, AZ-104 + AZ-305 makes you an Azure Architect, and AZ-104 + AZ-204 + AI-103 (GA 2026-06) is a strong combination as an AI developer who also knows Azure operations. For security focus, try AZ-104 + SC-300 + SC-500 (GA 2026-09); for data focus, AZ-104 + DP-300 / DP-700. Even after the July 2026 retirement, an AZ-204 pass stays on your resume for the 12-month validity window, so a last-minute attempt still has value.
