MB-310 Study Guide: Things You Must Know to Pass the Dynamics 365 Finance Exam

If you work with Dynamics 365 Finance and you are thinking about getting certified, the MB-310 is your exam. As a Microsoft Certified Trainer who has delivered this course and guided consultants through the curriculum, I can tell you that the MB-310 is one of the few Dynamics 365 exams that genuinely catches experienced people out — not because the topics are obscure, but because finance has its own internal logic and the exam tests that logic precisely.

I have seen senior finance consultants with years of project experience fail the MB-310 because they knew how to get things done in the system, but had never stopped to understand exactly why the system works the way it does.

That distinction, between doing and understanding, is what this exam is really testing.

I have seen senior finance consultants with years of project experience fail the MB-310 because they knew how to get things done in the system, but had never stopped to understand exactly why the system works the way it does. That distinction — between doing and understanding — is what this exam is really testing.

What is the MB-310 certification?

The MB-310 exam earns you the Microsoft Certified: Dynamics 365 Finance Functional Consultant Associate certification. It is the official Microsoft credential for consultants who implement and configure the Finance module within the Finance and Operations apps suite — the ERP application used by large and mid-market organisations to manage their entire financial operation.

The certification is renewed annually. Unlike most other Dynamics 365 exams, the MB-310 is only available in English and Japanese, which matters if English is not your first language — factor that into your preparation time.

Who needs the MB-310?

Finance functional consultants: people who configure the general ledger, accounts payable, accounts receivable, cash and bank management, budgeting, fixed assets, and expense management in Dynamics 365 Finance implementations.

If you work in a broader F&O role but Finance is your specialist area, this is the certification that validates it. If you are more on the supply chain or manufacturing side, the MB-330 or MB-335 are more relevant to your work.

As with all Microsoft certifications, no employer is legally required to ask for it. But Microsoft partner companies earn points towards their partner status when their consultants hold active certifications — which means your MB-310 has a direct commercial value to any partner you work for, even if nobody mentions it at the interview stage.

Self-directed learning or instructor-led training?

The official MB-310T00 course material is free on Microsoft Learn. If you already implement Dynamics 365 Finance day to day, self-study is a legitimate preparation route — the content is thorough and kept up to date with each exam revision.

The case for instructor-led training is strongest if you are newer to the Finance module, or if you have practical experience but gaps in your understanding of the underlying configuration logic. The course runs over four days using a live Dynamics 365 sandbox, which matters for a Finance exam because a lot of what you need to understand — posting profiles, fiscal calendars, budget control rules — only fully makes sense when you watch it behave in real time and then configure it yourself.

Is e-learning from third parties worth it?

There are MB-310 courses on Udemy and similar platforms, typically running five to eight hours. These are fine for someone who wants to understand what Dynamics 365 Finance does before committing to a full preparation programme, but they do not go deep enough to get you through the exam. The MB-310 tests configuration knowledge at a level of detail that short video courses do not reach.

What skills does the MB-310 test, and what is the weighting?

The exam currently covers five areas:

• Set up and configure financial management — 20–25%

• Implement and manage accounts receivable, credit, collections, and subscription billing — 15–20%

• Implement and manage accounts payable and expenses — 10–15%

• Manage budgeting and fixed assets — 15–20%

• Configure and manage financial reporting and consolidation — 15–20%

• Financial management setup is the single largest area, which surprises candidates who have spent most of their project time in AP or AR.

  
  

The exam expects you to understand the foundational layer — chart of accounts, financial dimensions, fiscal calendars, ledger configuration — at a level of detail most consultants have never needed to think about explicitly on a live project.

How hard is the MB-310?

Harder than most people expect, and specifically hard in a way that experience does not automatically protect you from. The exam is not trying to catch you out with trick questions — it is testing whether you understand the system's design, not just its behaviour.

A good example is the year-end close process. On a real project, most consultants run the year-end close following a checklist someone else created, or they do it once and never need to think about it again. The MB-310 asks you to understand exactly what happens when you set "Delete close of year transactions" to Yes versus No, what "Fiscal year status permanently closed" actually prevents, and how your Year-end close template configuration determines what flows into retained earnings. These are details that experienced consultants frequently have to look up — the exam expects you to know them cold.

What types of questions will you get?

Multiple choice with multiple correct answers: Common in the MB-310. The question may have two, three, or even four correct answers, and you need to select all of them. Missing one costs you the points for that question.

Scenario-based questions: A client situation is described, and you have to identify the correct configuration steps. These questions often include a deliberate mismatch between what sounds like the right answer from a business logic perspective and what the correct answer actually is in Dynamics 365.

Hotspot and drag-and-drop: You match configuration options to requirements, or arrange steps in the correct order. Year-end close and budget setup appear frequently in this format.

You have 100 minutes for between 40 and 60 questions. The pass mark is 700 out of 1000.

Is the exam included with instructor-led training?

No. Third-party training providers do not include the exam. You book it separately through Pearson VUE at pearsonvue.com/microsoft. Microsoft keeps training and assessment separate by design — it means every certified consultant earned their certification independently, which is what makes the credential meaningful.

The 6 things finance consultants get wrong in the MB-310

1. They underestimate financial dimensions

Financial dimensions are everywhere in Dynamics 365 Finance — on transactions, on accounts, on customer and vendor records, and on fixed assets. The exam tests not just what dimensions are but how they interact with account structures, advanced rule structures, and the chart of accounts. A question might describe a scenario where a particular dimension combination is not posting correctly and ask you to identify whether the problem is in the account structure, the advanced rule structure, or the financial dimension configuration itself. Candidates who know dimensions exist but have never had to troubleshoot them will struggle here.

2. They confuse fiscal calendars with ledger calendars

These are two separate things in Dynamics 365 Finance, and the exam absolutely exploits that. The fiscal calendar defines your financial years and periods for accounting purposes. The ledger calendar is what you assign to a legal entity and use to control which periods are open or closed for posting. A question might describe a scenario where a company needs to post accounting adjustments into a prior year's Period 13 and ask what needs to be configured — the answer involves the ledger calendar and the year-end close template together, not just one or the other.

3. They do not know when to use posting definitions versus posting profiles

This is one of the most commonly tested distinctions in the MB-310 and one of the most frequently misunderstood in real life. Vendor and customer posting profiles control where transactions post to the general ledger by default. Posting definitions go further — they allow you to create multiple balanced ledger entries from a single transaction based on specific transaction types or account combinations. The exam will give you a business requirement and ask which of the two applies. If the requirement involves defaulting a dimension from a vendor record, that is a posting profile. If the requirement involves generating multiple balanced entries automatically from a single transaction, that is a posting definition.

4. They skip revenue recognition because it feels niche

Revenue recognition — including deferred revenue schedules, revenue allocation, and subscription billing — appears in the exam and is consistently one of the areas where candidates lose points. It feels like an advanced or niche feature that only applies to certain industries, so people deprioritise it during study. Do not. The exam covers how to configure revenue deferral defaults, how to set up recognition schedules, and how subscription billing connects to accounts receivable. If you have not configured this on a project, spend time on the Microsoft Learn modules specifically.

5. They treat fixed assets and asset leasing as one topic

Fixed assets and asset leasing are in the same exam domain, which leads candidates to study them together and assume they follow the same logic. They do not. Fixed assets in Dynamics 365 Finance follow the traditional depreciation model — depreciation books, depreciation profiles, and acquisition posting. Asset leasing implements IFRS 16 and ASC 842, which means right-of-use assets, lease liabilities, interest expense, and a completely different set of journals. The exam tests both and expects you to know which applies to which scenario without prompting.

6. They underestimate how much budget control logic matters

Budgeting accounts for 15–20% of the exam but gets treated as an afterthought by candidates whose project experience has been in the transactional areas. The exam is particularly interested in budget control configuration — specifically, the difference between budget control rules, budget control groups, and over-budget permissions, and how the system behaves when a transaction exceeds the available budget, depending on how these are set up. A common question pattern is: a company has configured budget control, but transactions are still posting when the budget is exceeded. What is the likely cause? Knowing the answer requires understanding the full budget control configuration chain, not just knowing that budget control exists.

What to do after you pass

Your certification badge will appear in your Microsoft Learn account within a few days of passing, linked to your Credly profile for sharing on LinkedIn. Set a reminder for your renewal — Microsoft will email you, but renewal assessments are shorter and easier than the original exam, and there is no reason to let the certification lapse. The renewal is free and takes around 45 minutes.

Preparing for the MB-310 with an expert trainer makes a significant difference in the configuration topics that the exam tests hardest. Our MB-310 instructor-led course runs over four days on Microsoft Teams, in small groups, with a live Dynamics 365 environment throughout.
