What Is AZ-204?

What Is AZ-204, Exactly?

AZ-204 is the exam code for "Developing Solutions for Microsoft Azure," the assessment that leads to the Microsoft Certified: Azure Developer Associate credential. It is not a course or a badge you get for attending training - it is a specific, proctored technical exam that tests whether you can design, build, test, and maintain cloud applications and services on Azure. If you've seen the term "AZ-204 certification" used loosely, it usually refers to the credential you earn after passing this exact exam.

Unlike broad conceptual certifications, AZ-204 is deliberately hands-on in spirit. It assumes you've written code that talks to Azure services, not just read about them. For a deeper breakdown of exactly what the credential represents, see our companion piece on AZ-204 Certification, and if you're still untangling terminology, AZ-204 Meaning and What Does AZ-204 Stand For? cover the naming convention in more detail.

Who Runs the Exam and Where You Take It

Microsoft Corporation is the governing body - it owns the exam content, the skills-measured outline, and the certification itself. Delivery, however, is handled by Pearson VUE, Microsoft's testing partner. You can sit the exam in one of two ways:

• In-person at a Pearson VUE test center, where you check in with ID and take the exam on a locked-down workstation.
• Online via OnVUE, Pearson's remote proctoring system, which lets you test from home or office under webcam supervision.

Both delivery methods use the identical exam content and passing standard - choosing one over the other is purely a logistics decision based on your environment and comfort with remote proctoring.

Exam Format, Length, and Scoring

AZ-204 is a proctored Microsoft technical exam. Microsoft doesn't publish an exact question count, but most Microsoft certification exams - AZ-204 included - typically fall in the 40-60 question range, and this can shift slightly as Microsoft updates the exam over time. You get 100 minutes to complete it.

Expect a mix of question types rather than a single uniform style:

• Traditional multiple-choice and multiple-response questions
• Interactive components (drag-and-drop, ordering steps, matching)
• Case studies that present a scenario and ask several related questions
• A small number of unscored items used for exam calibration - you won't know which ones these are

Scoring is reported on a scaled range of 1 to 1000, and you need 700 or higher to pass. Results are usually available within minutes of finishing, unless the exam version includes lab-based tasks, which can delay reporting.

The Five Skills Measured Domains

Microsoft organizes AZ-204 content into five domains, each with a published weight range. These weights tell you where to invest study time, and they are the single most useful piece of information for planning your prep.

For a domain-by-domain deep dive with more granular subtopics, our full AZ-204 Exam Domains 2026: Complete Guide to All 5 Content Areas walks through each one. We've also published standalone guides for the individual domains if you want to go deep on a single area: Domain 1, Domain 2, Domain 3, and Domain 4.

Who Actually Takes AZ-204

AZ-204 is aimed squarely at working developers, not IT generalists or architects. The people who pursue it typically fall into a few overlapping groups:

• Backend or full-stack developers whose teams are migrating applications to Azure
• Cloud engineers who write and deploy code against Azure Functions, App Service, or AKS
• Developers seeking a credential that signals hands-on Azure SDK, CLI, and PowerShell fluency to employers
• Consultants and contractors who need to demonstrate Azure development skills across multiple client environments

Prerequisites and Recommended Background

There is no formal prerequisite - Microsoft doesn't require you to hold another certification or pass a gatekeeping course before registering. That said, Microsoft explicitly recommends candidates have:

• At least two years of hands-on programming experience
• Working proficiency with Azure SDKs, the Azure CLI, and Azure PowerShell
• Comfort with Azure data storage options and how to establish data connections
• Practical experience with APIs, app authentication and authorization patterns
• Familiarity deploying compute and container workloads, plus debugging skills across these services

In practice, this means AZ-204 is not a beginner's first Azure exam. Candidates coming from AZ-900 (Fundamentals) with no coding background typically struggle. This is one reason the exam has a reputation for being more demanding than entry-level Azure exams - a topic explored further in How Hard Is the AZ-204 Exam? Complete Difficulty Guide 2026.

Registration, Fee, and Retake Rules

Registration happens through Microsoft's certification portal, which hands off scheduling to Pearson VUE. Here's what the mechanics actually look like:

• Fee: Pricing varies by country or region, but Microsoft's exam FAQ states Associate and Expert-level exams typically cost US$165. There is no member versus nonmember pricing split - everyone pays the same published rate for their region.
• Delivery choice: Pearson VUE test center or OnVUE online proctoring, selected during scheduling.
• Exam sandbox: Microsoft provides an exam sandbox environment so you can get comfortable with the interface before your actual attempt counts.
• Learn access during the exam: Some role-based exams allow limited Microsoft Learn access during the test under Microsoft's exam rules, but this does not add extra time to your 100-minute clock.
• Retakes: If you fail on your first attempt, you must wait at least 24 hours before retaking. Subsequent retake waiting periods can be longer, so check Microsoft's current retake policy before scheduling again.

Certification Validity and Renewal

Once earned, the Azure Developer Associate certification is valid for 12 months. Renewal is handled entirely online - Microsoft doesn't make you retake the full AZ-204 exam. Instead, you complete a free renewal assessment through Microsoft Learn before your certification expires. This assessment covers updated content and can typically be attempted starting a set window before your expiration date.

This renewal-through-Learn-assessment model applies to role-based certifications generally, and it's a meaningful advantage over older certification programs that forced a full re-exam every few years.

The July 2026 Retirement Deadline

This is the detail candidates most often miss: the AZ-204 exam, its certification, and its renewal assessments are all scheduled to retire on July 31, 2026. After that date, it will no longer be possible to earn the Azure Developer Associate certification through this exam, nor to renew it through the current assessment path.

If you're currently holding or pursuing this credential, this deadline should shape your planning in two ways:

• If you haven't taken AZ-204 yet, you have a defined window to schedule and pass it before retirement.
• If you already hold the certification, watch for Microsoft's guidance on what (if anything) replaces it, since role-based Azure certifications are periodically refreshed with new exam codes and updated skills outlines.

Building a Prep Plan Around the Domains

Because Develop Azure compute solutions (25-30%) and Connect to and consume Azure services and third-party services (20-25%) together make up nearly half the exam, your study schedule should weight time accordingly rather than splitting evenly across all five domains.

This weighting-first approach - rather than a generic even split - is the core idea behind our full AZ-204 Study Guide 2026: How to Pass on Your First Attempt, which goes further into resource selection and lab environments. Whichever schedule you use, timed practice under exam-like conditions on our practice test platform is the best way to confirm you can finish all questions within the 100-minute window.
