MB-920 is the Dynamics 365 fundamentals exam for ERP processes, covering finance, supply chain, commerce, and human resources; MB-910 is the corresponding fundamentals exam for customer engagement apps.
The practical difficulty of MB-920 comes from breadth rather than technical depth. Candidates are expected to describe Microsoft Dynamics 365 Finance, Supply Chain Management, Commerce, and Human Resources capabilities, and to recognise business scenarios where those capabilities apply. They are not expected to perform implementation work at the level of exams such as MB-300 or MB-500.
Last updated: 2026. Microsoft can revise exam objectives and skills measured over time, so candidates should check the current Microsoft Learn exam page before booking. When the syllabus changes, preparation should follow the latest skills outline rather than older blog posts, videos, or practice questions.
How difficult is MB-920?
MB-920 is usually manageable for candidates who understand basic business processes, but it can feel harder than expected for those new to ERP terminology. The exam asks candidates to connect concepts such as general ledger, procurement, inventory, fulfilment, point-of-sale, employee lifecycle, and reporting to the relevant Dynamics 365 application area. That makes it different from a product-navigation test and different from a deep configuration exam.
The most common preparation mistake is studying implementation-heavy material too early. Deep setup work, data migration projects, extensions, and form customisation belong to more advanced Dynamics 365 paths. For MB-920, time is better spent understanding what each ERP application does, what business problems it addresses, and how common processes fit together across finance and operations.
Hands-on practice is helpful, although it is not mandatory. Even at fundamentals level, scenario questions may refer to product capabilities in a way that is easier to recognise after seeing the applications or guided Microsoft Learn exercises. A trial or sandbox environment can make abstract terms easier to remember, especially in Supply Chain Management and Commerce.
What MB-920 tests, and what it does not
The official skills measured for MB-920 are centred on describing capabilities and business value across the Dynamics 365 ERP portfolio. Candidates should expect coverage across Finance, Supply Chain Management, Commerce, and Human Resources, with questions framed around business needs rather than detailed technical implementation steps.
A useful way to think about the exam is as a topic map. Finance covers accounting, budgeting, financial reporting, payables, receivables, and related controls. Supply Chain Management covers inventory, procurement, warehousing, production concepts, and fulfilment. Commerce covers retail channels, store operations, e-commerce scenarios, customer experiences, and fraud or payment-related capabilities at a conceptual level. Human Resources covers employee records, benefits, compensation, leave, and workforce processes.
That scope is broad, but it is still fundamentals-level. Candidates do not need to design integrations, customise forms, build extensions, migrate production data, or configure a full enterprise implementation. Those areas can be useful later in a Dynamics 365 career, but they can distract from the exam if they become the main focus during MB-920 preparation.
Where candidates usually find MB-920 harder
Finance is often the most familiar domain for candidates who have worked near accounting, purchasing, billing, or reporting. Basic ideas such as general ledger, accounts payable, accounts receivable, budgets, and financial statements appear in many organisations, so the challenge is often mapping familiar business language to Dynamics 365 Finance capabilities.
Supply Chain Management can be more demanding for candidates without operations experience. Inventory, warehouse processes, procurement, production, planning, and fulfilment are connected, and exam scenarios may describe a business problem rather than naming the feature directly. Candidates who only memorise feature names can struggle when a question describes stock movement, demand planning, or order fulfilment in plain business terms.
Commerce is another area that can trip up non-ERP candidates because it spans online, in-store, and back-office retail concepts. A question may involve customer experience, channel management, pricing, payments, product information, or fraud protection. The difficulty is not advanced configuration; it is recognising which Dynamics 365 Commerce capability fits the scenario.
Human Resources is usually more approachable, but it should not be ignored. Candidates still need to understand how employee data, leave and absence, benefits, compensation, and personnel management fit into the wider ERP story. A light study pass over HR can leave easy marks behind if the terminology is unfamiliar.
A realistic study plan for MB-920
Preparation time depends heavily on prior exposure. A candidate with business, finance, procurement, retail, HR, or ERP experience may be able to prepare part-time in two to three weeks. Someone new to ERP should plan for four weeks or more, especially if Supply Chain Management and Commerce are unfamiliar.
The strongest study plans start with the current Microsoft Learn skills outline, then use the Learn modules to fill gaps by domain. Candidates should read the exam page first, note the weighting and topics, and then work through the learning content with a simple goal: being able to explain each business scenario in plain English and identify the Dynamics 365 application that supports it.
- Start by reviewing the current MB-920 skills measured on Microsoft Learn and marking unfamiliar terms.
- Study Finance and Supply Chain Management first because they carry much of the ERP process language.
- Use Microsoft Learn modules and product screenshots to connect terminology with real capabilities.
- Spend focused time on Commerce and Human Resources rather than treating them as minor topics.
- Use sample questions to practise scenario reading, not to memorise answers.
A structured class can help when time is short or when the ERP vocabulary is new. Readynez offers an MB-920 preparation option through its Microsoft Dynamics 365 Fundamentals ERP course, but candidates can also prepare effectively through Microsoft Learn, careful note-taking, and targeted practice if they keep the exam scope clear.
MB-920 versus MB-910: which fundamentals exam fits?
The simplest distinction is ERP versus CRM. MB-920 is the better fit for candidates interested in finance, procurement, inventory, retail, operations, human resources, and back-office business processes. MB-910 is the better fit for candidates interested in sales, customer service, marketing, field service, project operations, and customer engagement work.
This choice matters because the two exams use different business vocabulary. A career switcher aiming for business analyst, ERP consultant, finance systems, supply chain, or operations roles will usually get more relevant grounding from MB-920. Someone aiming toward CRM consultant, customer service analyst, sales operations, or marketing automation work may find MB-910 more aligned. Readers comparing both tracks should use the distinction between ERP and CRM as the starting point before choosing a study route.
Exam-day approach
MB-920 questions should be approached as business-scenario questions first. Candidates may see multiple-choice and multi-select formats, and Microsoft exams can include scenario wording that requires careful reading. The safest approach is to identify the business problem, remove options that belong to the wrong application area, and avoid adding implementation assumptions that are not stated in the question.
Time management should be simple and disciplined. Candidates should answer confident questions first, flag uncertain ones for review, and return to them after completing the remaining items. Overthinking can be a problem in fundamentals exams because candidates sometimes search for a technical configuration answer when the question is only asking for a capability or business fit.
A representative practice scenario, paraphrased in the style of Microsoft’s public exam preparation guidance, might ask which Dynamics 365 application supports a retailer that wants consistent product information across online and store channels. The learning point is to recognise the Commerce scenario, not to design the implementation. This type of practice helps candidates stay aligned with the exam’s fundamentals purpose.
Using MB-920 as a starting point
MB-920 is worth taking when a candidate wants a recognised grounding in the ERP side of Dynamics 365 without committing immediately to a role-based implementation exam. It can be especially useful for junior consultants, business analysts, career switchers, and professionals who work near finance, operations, retail, HR, or supply chain processes.
After passing, the next step should depend on the target role rather than on collecting exams randomly. Finance-focused candidates may move toward deeper Dynamics 365 Finance learning, operations-focused candidates may build supply chain knowledge, and analysts may benefit from learning more about reporting, process mapping, and integration points. Candidates who want a broader Microsoft learning route can review Microsoft training options and, where appropriate, Unlimited Microsoft Training as part of a longer development plan.
The key takeaway is that MB-920 is challenging for the right reason: it tests whether candidates understand ERP business processes across several Dynamics 365 applications. A focused study plan, current Microsoft Learn objectives, and a clear boundary between fundamentals and implementation detail will usually make preparation more efficient.
