MB-910 Dynamics 365 Fundamentals: Entering the CRM World
If you are stepping into the Microsoft business-applications world, MB-910 is usually the first door. So the honest question most people ask is: how do I pass MB-910 without wasting weeks on the wrong material? This guide lays out exactly what the exam measures, how it is scored, and where a focused MB-910 mock test earns its place in your plan.
What MB-910 actually is
The Microsoft Dynamics 365 Fundamentals (CRM) (MB-910) exam is a conceptual, breadth-first credential. It does not ask you to configure production environments or write code. Instead it checks that you understand what the customer-engagement side of Dynamics 365 does, how the apps fit together, and which app solves which business problem. That makes it approachable for sales staff, analysts, consultants, and anyone deciding whether Dynamics 365 is the right platform, not just full-time administrators.
The exam is delivered as a linear paper: 50 questions, 100 minutes, which works out to roughly two minutes per question. You need a scaled score of 700 on a 0 to 1000 range to pass. One note on the numbers: Microsoft publishes no official question count, so the 50-item length is ours, but the 700/1000 pass standard is Microsoft's own.
How the exam is weighted
The value of the exam comes from knowing where the marks live. The functional groups below are drawn from Microsoft's published MB-910 study guide, verified on 24 August 2026. Study to the weighting, not evenly.
| Functional group | Weight |
|---|---|
| Describe Dynamics 365 Sales | 24% |
| Describe Dynamics 365 Customer Service | 22% |
| Describe Dynamics 365 Customer Insights | 18% |
| Describe Dynamics 365 Field Service | 18% |
| Explore the core capabilities of customer engagement apps in Dynamics 365 | 18% |
Sales and Customer Service together account for nearly half the paper, so give them the deepest passes. But the four smaller groups are each substantial enough that ignoring one can cost you the exam on its own. Treat the shared "core capabilities" group as the connective tissue: it is where questions about how the apps sit on a common platform and share data tend to land.
A realistic study plan
Start with Microsoft Learn's free modules for each functional group, in weight order. Read for understanding of scenarios rather than memorising feature lists, because the questions are phrased as business situations. Once you can explain, in plain language, which Dynamics 365 app a given team would use and why, you are close.
Then pressure-test that understanding. A good practise exam under time does two things a reading pass cannot: it exposes the topics you only think you know, and it trains the two-minute-per-question pace so the real sitting feels familiar. Our mock test pack covers every functional group at its published weighting, so the distribution of your practice mirrors the distribution of the real paper.
What this mock contains, honestly
One thing to be clear about before you buy. The real MB-910 exam may include interactive components: tasks carried out against the product rather than answered as multiple choice. This mock is multiple-choice and multiple-response only. It covers every functional group at its published weighting, but you will not practise the interactive interface here. Use the mock to lock down the concepts and the pacing, and spend some time clicking around a Dynamics 365 trial so the hands-on portions do not surprise you. A practise exam for Dynamics 365 is a knowledge check, not a substitute for touching the product.
Bringing it together
MB-910 rewards steady, weighted preparation over cramming. Read the Learn modules in weight order, confirm you can reason about each app in business terms, and then rehearse under exam timing until 700 out of 1000 feels comfortable rather than hopeful. If you want a structured set of questions to rehearse with, browse the Microsoft Dynamics 365 Fundamentals (CRM) (MB-910) mock test or go straight ahead and get a mock test pack. Prepare to the blueprint, practise to the clock, and MB-910 becomes a predictable, passable first step into the Dynamics 365 ecosystem.
