What is AZ-204 (Azure Developer Associate)?

AZ-204 is the Associate-level Microsoft certification for developers building solutions on Azure. It validates competency across the full developer workflow: compute, storage, security, monitoring, and integration with other Azure and third-party services.

It’s also the most popular Azure cert for developers entering the Microsoft cloud space — over 200K holders globally as of 2026.

Should you pursue AZ-204?

Take it if you’re:

• A developer with 1-2+ years of any cloud or modern application development experience.
• Targeting Microsoft-shop employers — banks, government, healthcare, large enterprise.
• Already comfortable with C# .NET, Node.js, or Python — the exam tests across multiple languages.
• Working toward AZ-400 (DevOps Engineer Expert) which requires AZ-204 OR AZ-104 as prerequisite.

Skip it if:

• You target AWS — get AWS Developer Associate (DVA-C02) instead.
• You’re an architect, not a developer — AZ-305 is more relevant.

Exam format

The 5 exam domains

• Azure Developer (3-5 yrs + AZ-204): $115K-$155K base.
• Senior Azure Developer / Architect track: $145K-$200K base.
• Microsoft-shop premium: 5-10% above AWS-equivalent in regulated industries.

Best ways to prepare for AZ-204

Honest ranking, with community consensus weighted heavily:

#1 (free, official, genuinely best): Microsoft Learn AZ-204 path

Microsoft’s official learning path, completely free. ~30+ hours with hands-on Azure trial labs. For AZ-204 specifically, Microsoft Learn is consistently the most-recommended primary resource on r/AzureCertification.

#2 (paid alternative): Scott Duffy or Tim Warner Udemy AZ-204

Scott Duffy’s AZ-204 on Udemy ($15-30 with discount). Most-purchased AZ-204 course outside Microsoft Learn. Useful if you prefer paid structured learning over Microsoft’s modular format.

#3 (essential): Practice tests

Microsoft Official Practice Assessment (free). MeasureUp ($99) for closest exam difficulty. Whizlabs AZ-204 ($19-24) for budget option.

#4 (for portfolio + cert combo): Udacity Cloud Developer using Azure Nanodegree

Udacity Cloud Developer using Microsoft Azure Nanodegree (nd081) — intermediate level, 51 hours, explicitly designed to prep for AZ-204. Covers App Service, Functions, deployment slots, Managed Identities, Key Vault.

$399/month + ~$50-100/month Azure costs. The Udacity program goes deeper on hands-on coding than Microsoft Learn’s labs — useful for portfolio. See our full Cloud Developer review.

Honest framing: Microsoft Learn is sufficient for the exam. Udacity is for portfolio depth, not a substitute for the official path.

8-week study plan

1. Weeks 1-2: Microsoft Learn Domain 1 (Compute) + hands-on App Service + Functions deployments.
2. Weeks 3-4: Domain 2 (Storage) + Domain 3 (Security). Cosmos DB partitioning + Managed Identities exercises.
3. Weeks 5-6: Domain 4 (Monitor) + Domain 5 (Integration). Application Insights + Service Bus + Logic Apps.
4. Week 7: Practice tests, weak-spot review.
5. Week 8: Final review, exam.

Frequently Asked Questions

How hard is AZ-204?

Moderate. Easier than AZ-305 (Solutions Architect Expert), harder than AZ-104 (Administrator). 60-70% pass rate among prepared candidates.

What languages do I need to know for AZ-204?

The exam is language-agnostic but C# .NET, Node.js, and Python questions appear most often. You’ll see code samples — ability to read multiple languages helps.

How does AZ-204 compare to AWS Developer Associate (DVA-C02)?

Roughly equivalent. AZ-204 emphasizes Azure’s unified compute platform (App Service, Functions); DVA-C02 emphasizes AWS’s service variety. Pick based on your target employer’s cloud. See AWS vs Azure.

Is AZ-204 worth it?

Yes for Azure developers. Adds ~10% to median offers at junior-mid level + opens AZ-400 (DevOps Expert) path.

What comes after AZ-204?

AZ-400 (DevOps Engineer Expert) or AZ-305 (Solutions Architect Expert) for senior-track progression.
