Is AZ-204 Being Retired? Yes, on July 31, 2026 (And What Replaces It)

Yes. Microsoft's AZ-204 study guide carries this warning: "This exam will retire on July 31, 2026, at 11:59 PM Central Standard Time." The Azure Developer Associate certification, its exam, and its renewal assessments all retire on that date. The replacement is Exam AI-200 (Developing AI Cloud Solutions on Azure), which earns the Microsoft Certified: Azure AI Cloud Developer Associate credential. Already hold AZ-204? It stays valid until it expires. Haven't booked the exam yet? Microsoft's own guidance is to prepare for AI-200 instead.

Last updated July 2026. Details below come from Microsoft Learn and Microsoft's Skills Hub retirement announcement (timeline updated May 28, 2026).

Is AZ-204 being retired?

It is. The certification page says it plainly: "This certification, related exam, and renewal assessments will retire on July 31, 2026. You will no longer be able to earn or renew this certification after this date." A hard cutoff, not a phase-out.

The phrase most people skip is "and renewal assessments." Microsoft associate certifications expire after 12 months, and you keep them alive with a free, unproctored, open-book renewal assessment on Microsoft Learn. When AZ-204's renewal assessment retires with the exam, that door closes permanently, and whatever expiry date sits on your transcript is the last one you get. More in our guide to whether Microsoft certifications expire.

What is the AZ-204 retirement date?

July 31, 2026, at 11:59 PM Central Standard Time. AZ-204 isn't being retired on its own, though. It sits in the middle of a coordinated wave Microsoft announced while rebuilding the Azure role-based track around AI workloads.

Note what is not in that table: AZ-104 (Azure Administrator Associate). It isn't retiring, so if you want a stable Azure credential to anchor a study plan around, that's it, and you can build drills with our AZ-104 practice test generator. On the security side, AZ-500 gives way to SC-500 a month after AZ-204 goes, so compare the AZ-500 question generator with the SC-500 practice questions if you're tracking that too.

What replaces AZ-204?

Exam AI-200: Developing AI Cloud Solutions on Azure, earning the Azure AI Cloud Developer Associate certification. The beta marker came off its certification page around July 9, 2026, so it's generally available now. It costs $165 USD in the US, same as AZ-204, and runs 120 minutes instead of 100.

Two catches. AI-200 is English only at launch, versus 10 languages for AZ-204. And Microsoft's page says "The Practice Assessment for this exam is not currently available," so the free official practice test doesn't exist yet.

Is AI-200 just AZ-204 with AI bolted on?

No, and this is where almost everyone guesses wrong. The name says "AI Cloud Developer," so people assume Azure OpenAI, prompt engineering, agents, RAG chatbots. Read the skills outline: none of it is there. AI-200 contains no Azure OpenAI, no Azure AI Foundry, no Copilot Studio, no Azure AI Search, no prompt engineering, and no agents. All of that lives in AI-103, the AI-102 replacement.

AI-200 is a backend developer exam: AZ-204's compute, messaging, and observability core with the data layer rewritten for vector workloads. The four domains and their published weights:

• Develop containerized solutions on Azure (20 to 25%): Azure Container Registry and ACR Tasks, containers on App Service, Azure Container Apps (revisions, KEDA event-driven scaling), AKS via manifest files.
• Develop AI solutions by using Azure data management services (25 to 30%, the biggest domain): Cosmos DB for NoSQL (Request Units, consistency levels, indexing policies, storing and retrieving embeddings, vector similarity search, change feed processor), Azure Database for PostgreSQL (pgvector, sizing compute for vector workloads, RAG patterns with metadata filters), and Azure Managed Redis (caching, vector indexing).
• Connect to and consume Azure services (20 to 25%): Service Bus (dead-letter queues, topics, subscriptions), Event Grid, Azure Functions triggers and bindings.
• Secure, monitor, and troubleshoot Azure solutions (20 to 25%): Key Vault and secret rotation, App Configuration, OpenTelemetry distributed tracing, KQL queries.

The "AI" in AI-200 means data plumbing: embeddings, vector search, RAG retrieval, and the containers and telemetry holding them up. Not model behavior. Microsoft's recommended proficiency for AI-200 names Python and vector databases; AZ-204 was language-agnostic. Never touched pgvector or written a similarity query against Cosmos DB? That's your study gap, not prompt design. Drilling AI-200 practice questions built from the current skills outline is the fastest way to find out how wide that gap really is.

AZ-204 vs AI-200: what actually changed

What carries over: containers, Azure Functions, Service Bus, Event Grid, Cosmos DB, Key Vault, App Configuration, monitoring. Most AZ-204 study time isn't wasted. What is not in the AI-200 skills outline: App Service web app breadth, Blob Storage, Entra ID auth and MSAL, API Management, Event Hubs, Queue Storage, managed identity. Worth knowing before another weekend on MSAL token flows.

Is AI-200 harder than AZ-204?

Microsoft publishes no pass rates, so nobody can honestly rank the two. What is measurable: AI-200 gives you 20 more minutes, drops a broad chunk of AZ-204's surface area, and replaces it with a narrower, deeper data-layer topic set many .NET-first Azure developers have never worked with. If your day job is C# on App Service, AI-200 will feel unfamiliar. If you've been shipping RAG backends, it reads like an exam about your job.

One honest note on how developers prepare now. Plenty of the plumbing here (an ACR task, a Service Bus dead-letter handler, a pgvector index) is the kind of work where you'd let an AI coding agent plan and write the change and then review the diff. Fine for shipping. A trap for studying: reading correct code is not the same as producing it under a 120-minute timer. Build each one by hand at least once.

What happens to my AZ-204 certification after it retires?

Nothing is taken away. Per Microsoft's FAQ: "If you've already earned any of the retiring Certifications, your credential remains valid and, on your transcript, until it expires. Retirement does not revoke or invalidate Certifications that were earned."

The catch is the renewal window. Microsoft also says: "Can I still renew a soon-to-retire Certification? A. Yes, as long as it's eligible for renewal and you renew it before the Certification officially retires." So if your AZ-204 is renewal-eligible now, take the free assessment before July 31 and push the expiry out 12 months. After that date the renewal assessment is gone, the certification runs to its expiry, then moves to Historical Certifications. Still real, still verifiable, no longer current.

Should I still take AZ-204?

Microsoft's guidance is direct: "If you haven't registered for the exam, we strongly recommend that you prepare for and take the new exam instead." With weeks left on the clock, a fresh AZ-204 pass buys a credential that can never be renewed.

Finishing AZ-204 before the deadline? The facts that still apply: 100 minutes, $165 USD in the US, no formal prerequisite, 10 languages, 700 out of 1,000 to pass. Microsoft is explicit that "as this is a scaled score, it may not equal 70% of the points." Our AZ-204 practice test generator covers the current objectives while the exam is live.

Why your prep site probably hasn't caught up

With 18 days left on the clock, much of the paid prep industry still sells AZ-204 as a current exam with no mention of the retirement.

• ExamTopics markets AZ-204 as current with "Browse 487 Questions" and a "95.1% Average score during Real Exams at the Testing Centre" claim. Its AZ-204 page contains zero mentions of "retire," "July 31, 2026," or "AI-200." Its own footer admits "ExamTopics doesn't offer Real Microsoft Exam Questions."
• testpreptraining.com lists "Retirement Date: None," says the exam is "150 minutes" (it's 100) and that you need "700 out of 900" (the scale is 1 to 1,000), and still teaches the "Implement caching for solutions" objective Microsoft removed on April 11, 2025.
• k21academy.com still publishes the retired 10 to 15% monitoring weight (it's now 5 to 10%) and that same deleted caching objective.

Question banks drift, and they drift silently. Related myth from the same industry: Microsoft publishes no question count for any exam. Its one public statement is that "most Microsoft Certification exams typically contain between 40 to 60 questions; however, the number can vary depending on the exam." Any site quoting an exact count invented it.

How to study for an exam with no question bank

AI-200 is the awkward case: too new for Microsoft's own practice assessment, and the third-party banks are either nonexistent or recycled AZ-204 content in a new wrapper. What does exist and is trustworthy is Microsoft's documentation. So build the questions yourself. Pull the AI-200 study guide and the relevant Learn pages into a PDF, then generate exam questions from your own documentation and drill against Microsoft's real wording instead of somebody's stale copy of it. It fixes weighting too: bias the drills toward the 25 to 30% data management domain rather than spreading effort evenly across four domains that are not equally worth your time.

And read the study guide again the week you book. These pages move.
