TL;DR
Below are 12 free MB-800 practice questions, grouped by difficulty instead of by domain, so you can gauge where your actual skill level sits rather than which exam section you happen to know best. Every question is a Business Central configuration scenario, not a definition to recall, and every option — correct and incorrect — has a rationale. If you can consistently reason through the Hard tier, you are close to exam-ready.
These questions are grouped by how much reasoning they require, not by exam domain — Easy tests whether you know what a feature is for, Medium tests whether you can apply it to a scenario, and Hard tests whether you can pick between two features that could each plausibly apply. That progression mirrors how MB-800's own questions get harder: not through obscure trivia, but through scenarios where more than one Business Central feature looks tempting.
Read the full scenario before looking at the options, cover the rationale, and commit to an answer before scrolling. If you want the full domain-by-domain reference these questions are drawn from, see the MB-800 study guide.
Foundational Setup & Concepts
Question 1
A functional consultant is standing up a brand-new company in Business Central for a client and wants a guided, step-by-step way to configure the most common settings before entering any transactions.
Which feature should the consultant use?
- A) Configuration Package
- B) Data Migration Overview
- C) Assisted Setup
- D) Configuration Worksheet
Correct answer: C. Assisted Setup provides guided, wizard-style steps for common configuration tasks in a new company — exactly the "step-by-step" need described.
A is wrong: a Configuration Package moves settings/data between companies; it doesn't provide guided in-app steps for a first-time setup.
B is wrong: data migration overview tools bring in data from another system, not general setup guidance.
D is wrong: a Configuration Worksheet tracks planned settings across an implementation project; it is a planning artifact, not a guided in-product wizard.
Question 2
A client asks why Business Central doesn't require them to pick a specific general ledger account every time they post a sales invoice for a given customer and item.
What is the correct explanation?
- A) Business Central posts everything to a single default account by design
- B) Posting groups determine the correct G/L account automatically, based on the customer and item combination
- C) Dimensions determine which G/L account is used
- D) The user must manually select the account on every document
Correct answer: B. General and specific posting groups combine to route a transaction to the correct G/L account automatically, without manual selection each time.
A is wrong: Business Central supports many distinct accounts by posting group combination, not one universal default.
C is wrong: dimensions add reporting analysis on top of a posting; they don't determine which account is used.
D is wrong: manual account selection defeats the purpose of posting groups and isn't the standard configured behavior.
Question 3
A salesperson sends a customer a non-binding price offer for a set of items. The customer has not committed to buying, and nothing should be reserved or shipped yet.
Which document should the salesperson create?
- A) Sales Quote
- B) Sales Order
- C) Sales Invoice
- D) Blanket Sales Order
Correct answer: A. A Sales Quote is a non-binding offer with no inventory commitment — exactly the "nothing reserved yet" scenario.
B is wrong: a Sales Order represents a committed transaction ready to ship and invoice.
C is wrong: an invoice bills for goods/services already provided or ordered, not an unconfirmed offer.
D is wrong: a Blanket Sales Order is a committed agreement covering multiple future releases, not a non-binding offer.
Question 4
A single user finds a column on the Customer List unhelpful for their own work and wants to hide it, without changing what any other user sees.
What should the user do?
- A) Ask an administrator to redesign the page
- B) Create a new permission set
- C) Change the profile assigned to their role center
- D) Personalize the page
Correct answer: D. Personalization is an individual, per-user change — the only option of the four scoped to just one person.
A is wrong: page design changes affect everyone using that page, not just the requesting user.
B is wrong: permission sets control access to data and actions, not page layout.
C is wrong: changing a profile affects everyone assigned to that profile, which is broader than "just this user."

Question 5
A wholesaler wants revenue from a specific category of items — say, refurbished equipment — to post to a different G/L revenue account than everything else, but doesn't want to create a separate account for every customer who happens to buy that category.
What should the consultant configure?
- A) A customer posting group per customer
- B) A general posting group tied to the item category
- C) A new number series for the item category
- D) A dimension value for the item category
Correct answer: B. General posting groups (the product side) are exactly the mechanism for varying the G/L account by product/item type, independent of which customer is buying.
A is wrong: customer posting groups vary accounts by customer, which is the opposite of what's needed — the goal is category-based, not customer-based.
C is wrong: number series control document numbering, not G/L posting.
D is wrong: a dimension adds an analysis tag to a posting; it doesn't redirect which G/L account is used.
Question 6
Six months after go-live, finance asks to start tracking spend by internal project code. Thousands of transactions have already posted without this tracking, and reconfiguring or reposting them is not acceptable.
Which approach fits without disrupting history?
- A) Add a new shortcut dimension for project code
- B) Change an existing global dimension to represent project code
- C) Create a new account category for each project
- D) Add a new general posting group per project
Correct answer: A. Shortcut dimensions (3-8) can be introduced after go-live for new reporting needs without touching historical postings or redefining company-wide global dimensions.
B is wrong: changing a global dimension after go-live is disruptive — global dimensions are meant to be set once, early, because they're baked into every historical posting's structure.
C is wrong: account categories organize the chart of accounts for reporting, not transaction-level project tracking.
D is wrong: posting groups control which G/L account is hit, not analytical tracking by project.
Question 7
A manufacturer sells individually serialized, high-value machines. Each unit has a meaningfully different purchase cost, and management wants that exact unit cost to determine the cost of goods sold at the time of sale — not a blended figure.
Which item costing method fits this requirement?
- A) Average
- B) Standard
- C) FIFO
- D) Specific
Correct answer: D. Specific costing ties each individual unit to its own actual cost — the only method that preserves per-unit cost differences instead of blending them.
A is wrong: Average costing blends all on-hand cost together, which is precisely what management wants to avoid.
B is wrong: Standard costing uses a predetermined cost and tracks variances separately — not each unit's actual purchase cost.
C is wrong: FIFO consumes cost in receipt order, which can still mismatch a specific unit's actual cost when units aren't interchangeable.
Question 8
A posted sales invoice has an incorrect unit price on one line. The customer has not paid, and the finance team wants the correction to leave a clean, traceable audit trail with a new editable invoice, rather than an unresolved credit memo.
What is the correct action?
- A) Manually post a standalone credit memo and stop there
- B) Delete the posted invoice
- C) Use Correct Invoice
- D) Adjust the customer's balance directly in the Chart of Accounts
Correct answer: C. Correct Invoice automatically creates the offsetting credit memo and a new, editable invoice as one guided action, which is exactly the clean audit trail described.
A is wrong: a standalone credit memo with no replacement invoice leaves the customer without a corrected bill — an incomplete fix.
B is wrong: posted documents cannot simply be deleted in Business Central; that would break the audit trail entirely.
D is wrong: the Chart of Accounts holds G/L accounts, not customer balances, and manual adjustments there bypass the sales subledger.
Multi-Step Scenarios
Question 9
A posted general journal entry has the correct G/L account and amount, but the wrong department dimension. Reversing the entry and reposting it correctly would also reverse and repost two other correct entries batched in the same journal, which finance wants to avoid.
What is the most appropriate fix?
- A) Use the Dimension Correction Tool on just the affected entry
- B) Reverse the entire posted journal batch
- C) Post a manual adjusting journal entry to net out the difference
- D) Edit the dimension directly on the posted entry
Correct answer: A. The Dimension Correction Tool changes the dimension value on one already-posted entry in place, without touching the amount, account, or any other entry in the batch.
B is wrong: reversing the whole batch undoes the two entries that were already correct — exactly what finance wants to avoid.
C is wrong: a manual adjusting entry changes the G/L balance, but the actual problem is a dimension tag, not an amount — this doesn't fix the reporting issue.
D is wrong: dimensions on a posted entry can't simply be typed over; the correction tool exists specifically because direct edits to posted data aren't how Business Central works.
Question 10
A fixed asset with an original cost of $50,000 and accumulated depreciation of $38,000 (book value $12,000) is sold for $15,000.
What happens on disposal?
- A) A $50,000 loss is recorded because the asset sold for far less than its original cost
- B) No gain or loss is recorded; the transaction only clears the asset off the books
- C) A $3,000 gain on disposal is recorded
- D) A $12,000 loss is recorded because the entire book value is written off
Correct answer: C. Gain/loss on disposal is sale proceeds minus remaining book value: $15,000 − $12,000 = $3,000 gain, since the sale price exceeded what the asset was still carried at.
A is wrong: comparing sale price to original cost ignores accumulated depreciation entirely — the relevant baseline is book value, not original cost.
B is wrong: disposal always compares proceeds to book value; when they differ, a gain or loss is posted, not a wash.
D is wrong: this treats the entire book value as lost, ignoring that the asset was actually sold for more than that book value.
Question 11
A company operates three sales regions. Each region's sales staff should be able to view and post sales orders, but only for their own region — never another region's orders, even though all staff share the same job function.
What combination of settings correctly enforces this?
- A) Create a separate permission set per region with no other changes
- B) Apply a security filter for the region dimension on a shared Sales permission set
- C) Create a separate company per region
- D) Rely on user profiles alone to separate the regions
Correct answer: B. A security filter restricts the data a permission set can see/edit to a specific dimension value — combined with the sales permission set, this limits each user to their own region's orders.
A is wrong: separate permission sets alone still grant access to all sales orders unless a filter is layered on — object-level permission and data-level restriction are different things.
C is wrong: separate companies is a drastic, costly solution for what a security filter solves within one company.
D is wrong: profiles control page layout and role center defaults, not what data a user is authorized to see.
Question 12
A distributor's main warehouse is nearly full of a fast-selling item. They want to move a portion of that stock to a second warehouse, and going forward they need to track quantity, bin content, and reorder points for that item separately at each location.
What combination of Business Central features is required?
- A) A Transfer Order only
- B) A Stockkeeping Unit (SKU) only
- C) A new Item card for the second location
- D) A Stockkeeping Unit at the new location, plus a Transfer Order to move the physical stock
Correct answer: D. An SKU gives the same item location-specific settings (reorder point, bin, etc.), and a Transfer Order is the document that actually moves physical quantity between locations — both are needed together.
A is wrong: a Transfer Order alone moves the stock but doesn't create location-specific settings for future reordering and bin tracking.
B is wrong: an SKU alone sets up location-specific parameters but has no effect on physically moving existing inventory.
C is wrong: creating a duplicate Item card would split the item into two unrelated records, losing the shared item ledger history an SKU preserves.

If the Hard tier felt approachable, you're close. If Easy or Medium felt shaky, that's useful signal — go back to the domain those questions came from in the study guide before moving on.
Common Questions
Are these questions the same difficulty as the real MB-800 exam?
The Hard tier is built to be at least as demanding as a typical MB-800 scenario question — two features that could plausibly apply, with only one being correct once you account for every detail in the scenario. Easy and Medium are intentionally lighter, to isolate exactly where your knowledge gets shaky.
Why are the questions grouped by difficulty instead of by exam domain?
Grouping by domain tells you what you studied; grouping by difficulty tells you how well you can apply it. A candidate who aces Easy Financials questions but misses Hard Setup questions has a reasoning gap that domain-based grouping alone won't surface.
Do I need hands-on Business Central experience to answer these?
It helps significantly. MB-800 questions describe configuration inside specific pages, so candidates who have only read about a feature (rather than clicked through it in a sandbox or trial company) tend to struggle with the Medium and Hard tiers even when they know the terminology.
How many practice questions should I do before the real exam?
There's no official Microsoft number, but candidates who work through several hundred scenario-based questions across all four MB-800 domains report feeling more confident than those who rely on reading alone. Volume matters less than making sure you understand why each wrong answer is wrong, not just which letter is correct.
