DP-900 Exam Domains 2026: Complete Guide to All 4 Content Areas

How the DP-900 Blueprint Is Built

Microsoft Certified: Azure Data Fundamentals (DP-900) is organized around four weighted objective areas published in Microsoft's study guide for Exam DP-900. The guide's skills-measured list was current as of July 21, 2026, and the guide page itself was last updated June 23, 2026. Those four areas are the only weighted structure Microsoft gives candidates, so every hour of preparation should map back to one of them.

Two caveats from the study guide are worth absorbing early. First, the subtopic bullets under each domain are illustrative: the guide states that related topics may also appear. Treat the bullets as a floor, not a ceiling. Second, the percentages are published as ranges. Anyone who tells you that a domain is "exactly 27%" of your exam, or that you will see a fixed number of questions from each area, is inventing precision that Microsoft does not provide.

If you are new to the credential itself, the explainer What Is DP-900 Certification? covers the basics, and the DP-900 Study Guide 2026 turns the blueprint into a full preparation path. This article stays focused on the blueprint: what each domain asks of you and where candidates tend to lose points.

Domain 1: Describe core data concepts (25-30%)

This domain shares the highest published range and is the conceptual foundation for the other three. It is vendor-neutral in flavor: you are expected to understand data as a discipline before you map anything to an Azure service. Candidates who skip it because it "feels easy" often discover that the vocabulary resurfaces inside questions from every other domain.

Where points are lost

The most common error is confusing the workload with the technology. A question may describe many small, concurrent reads and writes that must be consistent, and the tested idea is "transactional workload," not a product name. Practice stating the workload type first, then selecting the service. Another frequent trap is the role boundary: a question about preparing and moving data between systems points to the data engineer, while building reports and visualizations points to the analyst.

Domain 2: Identify considerations for relational data on Azure (20-25%)

This domain moves from concepts to Azure's relational offerings. The verb in the title matters: you are asked to identify considerations, which means choosing appropriately among options rather than configuring them. Expect scenario-style prompts in which a business requirement leads you to a deployment choice.

The deployment-model question pattern

A reliable way to approach this domain is to rank the Azure options by how much control and responsibility the customer keeps. A scenario emphasizing minimal administration points toward the most managed option; a scenario emphasizing compatibility with an existing on-premises environment or operating-system-level access points toward the less managed end. Build a small comparison grid for yourself and quiz from it.

Domain 3: Describe considerations for working with non-relational data on Azure (15-20%)

This is the lowest-weighted domain, but it is also the one that introduces the most unfamiliar names for candidates coming from a relational background. A lower range does not mean skippable: a domain at 15-20% still represents a meaningful slice of the exam, and the concepts here appear in comparison questions that reach back into Domains 1 and 4.

Matching the model to the scenario

Questions here typically describe the shape of the data and the access pattern, not the product. Highly connected entities where relationships are the point suggest a graph model. Self-contained records with varying fields suggest a document model. Simple lookups by key suggest key-value. Learn to read the scenario for these signals before you scan the answer choices.

Domain 4: Describe an analytics workload on Azure (25-30%)

Tied with Domain 1 for the highest published range, this is the domain where candidates most often underinvest because it sounds like "someone else's job." It is not optional. Note also a small wording point in Microsoft's materials: the certification page and the skills-at-a-glance list name this area "Describe an analytics workload on Azure," while the guide's detailed heading omits "on Azure." Both refer to the same objective area.

Think in pipelines

The most effective mental model for this domain is a pipeline: sources feed ingestion, ingestion feeds processing and storage, storage feeds analysis, and analysis feeds visualization. For any service name you meet, place it on that pipeline. Questions frequently ask which service fits a particular stage, and a candidate who can locate the stage almost always narrows the choices to one.

Reading the Weight Ranges Correctly

Two practical conclusions follow. Together, Domains 1 and 4 represent the largest share of the exam by published range, so a plan that gives them proportionally more time is defensible. Second, do not convert ranges into midpoints and treat them as exact. Microsoft does not disclose how many items from each area appear on a given form, so a safe plan covers all four domains with real depth and does not gamble on skipping the lightest one.

Exam Mechanics That Shape How You Study

Knowing the domains is half the picture; knowing the conditions under which you will demonstrate them is the other half. These facts come from Microsoft's published documentation:

• Delivery: a proctored, computer-based assessment through Pearson VUE, with online proctoring available in supported regions (ID, system, and room requirements apply). Certiport is also offered to students and educators.
• Time: 45 minutes for the assessment, within a 65-minute Fundamentals seat time.
• Questions: the count varies. Microsoft publishes no fixed total for DP-900, and no scored/unscored split has been verified. Certiport's exam-length listing indexes 43-48 items, but that is a provider-specific listing with a retrieval/version caveat, not a guaranteed count for your attempt.
• Format: the specific question-type mix is undisclosed, and the exam may be interactive.
• Resources: Microsoft Learn is not available during Fundamentals exams, so you cannot look up a service name mid-exam.
• Passing score: 700 or greater on a 1-1,000 scaled score. This is not "70% correct," and some questions may be unscored. See DP-900 Passing Score 2026 for the full explanation.

On cost: the issuer page's indexed rendering lists a U.S. list price of $99, but country, tax, and eligible discounts affect what you actually pay, and Microsoft publishes no general member/non-member tier. The details are in DP-900 Certification Cost 2026. For retakes, Microsoft's policy allows a second attempt after 24 hours following a first failure, then 14 days between later attempts, with at most five attempts in 12 months. Fundamentals credentials do not expire and have no renewal assessment.

Microsoft's pass rate is not publicly disclosed in the official sources reviewed, so treat any specific percentage you see elsewhere with suspicion; DP-900 Pass Rate 2026 discusses what can and cannot be said. And because Microsoft does not require a preceding certification or minimum training hours, DP-900 Requirements 2026 explains the recommended (not mandatory) background.

What no-lookup means for your preparation

Because you cannot consult documentation, passive recognition is not enough. For each Azure service in the blueprint, you should be able to produce, from memory, its category (relational, non-relational, analytics, or visualization), its primary use case, and one scenario where it would be the wrong choice. A one-page summary such as the DP-900 Cheat Sheet is a good final-week review tool, but build your own version as you study, since writing it forces recall.

Sequencing the Domains Over Four Weeks

One short plan, tied to the blueprint rather than to generic habits. The order below follows dependency: concepts first, because every later domain reuses the vocabulary.

If you have only a short runway, compress by giving Domains 1 and 4 the larger share, but touch every domain. The DP-900 training overview describes the one-day Microsoft course and other preparation routes, and booking logistics are covered in DP-900 Exam Dates 2026.

Where the Credential Fits Professionally

DP-900 is a fundamentals-level credential. It signals data literacy on Azure rather than hands-on engineering depth, which makes it useful for people entering data roles, for sales and project staff who talk to technical teams, and for career changers building a first Microsoft credential. It is also a common stepping-stone toward role-based Azure data certifications. For how employers actually use it, see DP-900 Jobs; for compensation context, DP-900 Salary Guide 2026; and for a value judgment, Is the DP-900 Certification Worth It? The domains themselves are the best map of what a hiring manager will assume you can discuss: workload types, relational versus non-relational choices, and how analytics pipelines work.
