Azure Fundamentals: Complete Comparison of All 5 Exams (AZ-900 / DP-900 / SC-900 / MS-900 / AI-901)

The Microsoft Azure Fundamentals tier currently offers 5 exams: AZ-900 (general cloud), DP-900 (data), SC-900 (security), MS-900 (Microsoft 365), and AI-901 (AI, GA June 2026, successor to AI-900). They share the same spec — 99 USD, 45 minutes, 40-60 questions, 700/1000 passing score, no expiration — but their scopes, target roles, and learning efficiency differ substantially. This article compares all five along six axes so you can confidently pick the 1-3 exams that fit your career.

Microsoft's Fundamentals tier sits in the same entry-level category as AWS Cloud Practitioner and Google Cloud's CDL, but unlike its competitors Microsoft splits this category into five separate exams — a deliberate strategy. The design covers a vast ecosystem spanning Azure, Microsoft 365, Power Platform, and Dynamics 365, with each exam carrying its own standalone value.

Side-by-Side Comparison of All 5 Exams

How to Choose by Role

The most important selection axis is your role. Students and career changers without a settled role get the most general value from starting with AZ-900, but working professionals with a clear specialty get better learning efficiency by starting with the Fundamentals exam for their domain.

Cloud engineers and general SEs: AZ-900, no contest. It covers Azure's hierarchy, core services, and governance horizontally, and lays the foundation for Associate exams like AZ-104. It is the single most versatile certification in the Microsoft catalog.

Data engineers and data analysts: start with DP-900. You'll build a mental map of SQL, NoSQL, and analytics platforms (Synapse, Fabric, Databricks), and the progression into DP-203, DP-700, and DP-300 feels natural. Experienced practitioners can realistically skip AZ-900 and jump straight to DP-900.

Internal IT and SOC analysts: SC-900, no contest. You'll get the big picture on Zero Trust, Entra ID, the Microsoft Defender suite, and Purview, with a smooth path into SC-200, SC-300, SC-500, and SC-100. It is especially efficient for people who already know another SIEM or Active Directory.

Microsoft 365 sales and consultants: MS-900 is ideal. It centers on the business value and license SKUs of Teams, Exchange, SharePoint, Intune, and Copilot — directly applicable to customer pitches and contract negotiations. It is also standard as a prerequisite for Microsoft partner certifications.

AI engineers and data scientists: AI-901. Unlike the other four, mandatory Python is the key difference. It assumes you can use pip install and write basic Python, which raises the bar for business roles. As the successor to AI-900 (retired June 30, 2026), it is deliberately tilted toward technical professionals.

Difficulty Ranking and Study Load

Aggregating candidate write-ups, the difficulty ranking is roughly as follows: 1st AI-901 (high technical bar due to mandatory Python), 2nd SC-900 / DP-900 (many Defender products or SQL fundamentals required), 3rd AZ-900 / MS-900 (concept-centric and easiest). A working professional with 1-3 years of IT experience can reach pass-level on AZ-900 or MS-900 in 15-25 hours, but starting AI-901 with zero Python experience typically requires 60+ hours — that's the practical gap.

Recommended Exam Order

If you plan to take multiple exams, there are 5 recommended orders depending on your specialty.

Shared terminology (Entra ID, Storage Account, RBAC, Microsoft Purview) keeps reappearing, so study time shrinks as you progress. A typical pattern: someone who spent 30 hours on their first exam ends up passing the fifth one in just 10 hours — a clear compounding effect.

Strategies to Reduce Exam Fees

The combined exam fee for all five is 495 USD (around 66,000 JPY), but Microsoft Virtual Training Day can dramatically reduce the real cost.

A Virtual Training Day matched to each exam runs regularly (Japanese-language sessions are available). Completing Part 1 plus Part 2 ships you an exam voucher worth roughly 165 USD within 5 business days. AZ-900, DP-900, SC-900, and MS-900 are all available via this voucher route, so you can effectively drive the 396 USD fee for those four down to zero. AI-901 is the exception — because Training Day coverage comes after GA, for now you'll need to look for free vouchers through Microsoft Reactor events or Cloud Skills Challenge.

What to Take After Finishing All 5 Exams

After completing all 5 Fundamentals exams, you have a complete picture of the Microsoft certification landscape. The standard next step is to move into the Associate tier.

Infrastructure admin: AZ-104. Developer: AZ-204 (note the July 2026 retirement; successor not yet announced). Data engineer: DP-203 or DP-700. Database admin: DP-300. Security operations: SC-200. Identity admin: SC-300. AI developer: AI-103 (GA June 2026). Networking: AZ-700. Microsoft 365 admin: MS-102. Fundamentals graduates can realistically pick up an Associate exam in 3-6 months, and this is where your career axis starts to sharpen.
