MB-800 Practice Test
Microsoft Dynamics 365 Business Central Functional Consultant
MB-800 tests whether you can actually configure posting groups, set up dimensions, and process purchase and sales documents end to end in a live Business Central environment — not just recognize accounting terminology.
Our 500 scenario-based questions cover the full MB-800 blueprint across four domains: setting up Business Central (20-25%, covering creating and configuring a company using Assisted Setup, configuration worksheets and packages, and data migration, managing security including user profiles, permission sets, and security filters, setting up core functionality including report layouts, job queues, number series, and Copilot and agent capabilities, setting up dimensions including global and shortcut dimensions and default dimension priorities, and managing approvals using native workflows), configuring financials (30-35%, the largest domain, covering financial management setup including general ledger setup, accounting periods, payment terms, and currencies, managing the chart of accounts and account categories, setting up posting groups including general and inventory posting setup, setting up journals and bank accounts, setting up accounts payable and accounts receivable including vendor and customer accounts, and configuring fixed assets including depreciation books and methods), configuring sales and purchasing (10-15%, covering inventory setup including item categories, units of measure, locations, and costing methods, configuring master data for sales and purchasing including shipping agents and vendor lead times, and managing pricing and discounts for both vendors and customers), and performing Business Central operations (30-35%, covering basic tasks such as personalizing pages, applying filters, and using the Edit in Excel feature, processing purchases including quotes, purchase orders, and blanket purchase orders, processing sales including quotes, sales orders, and item availability, and processing financial documents including invoices, credit memos, and correcting posted documents). Every question is grounded against live Microsoft Learn Dynamics 365 Business Central documentation.

Sample MB-800 Practice Questions
10 real questions from the free MB-800bank. Pick an answer in your head, then open “Show answer” for the explanation.
1. On the Config Package Card page, what does selecting the Exclude Configuration Tables checkbox do?
- A. It removes customer and vendor tables from the package
- B. It prevents the package from being exported to Excel
- C. It disables the Get Related Tables action for that package
- D. It excludes configuration questionnaires, configuration templates, and configuration worksheet tables from the package
Show answer
Correct answer: D
Selecting Exclude Configuration Tables on the Config Package Card excludes the configuration questionnaire, template, and worksheet tables from the package; otherwise they are added automatically when the package is exported. It does not touch customer or vendor data, Excel export, or the Get Related Tables action.
2. An administrator wants to completely turn off all Copilot functionality across their Business Central environment using a single control. What should they know?
- A. Copilot is a system feature and cannot be turned fully on or off; administrators can just deactivate individual capabilities one at a time
- B. Copilot can be fully disabled from the Power Platform admin center with one toggle
- C. Copilot can be disabled by uninstalling the Business Central base application
- D. Copilot is disabled automatically for any environment created before 2024
Show answer
Correct answer: A
Per Microsoft's documentation, Copilot is a system feature and an integral part of Business Central; like most system features, you cannot turn Copilot on or off as a whole. Administrators instead deactivate individual capabilities on the Copilot & agent capabilities page. There is no Power Platform admin center master toggle, uninstalling the base app is not a supported approach, and there is no automatic disablement tied to environment creation date.
3. When you first sign up for Business Central, which company is provided as an empty container ready for you to enter your own data?
- A. CRONUS
- B. My Company
- C. Demonstration Company
- D. Evaluation Company
Show answer
Correct answer: B
Business Central provides a demonstration company plus an empty company named My Company. CRONUS and the demonstration company hold sample data rather than an empty starting point, and Business Central does not name a company "Evaluation Company" by default.
4. After using the Create G/L Acct. Journal Lines action while migrating opening balances through a configuration package, the journal lines appear with the correct accounts but no amounts. What is the correct next step?
- A. Delete the lines and manually re-enter them from scratch in the journal
- B. Export the journal table to Excel, enter the posting and balancing amounts from the legacy data, then import and apply the completed lines
- C. Post the journal lines as-is; Business Central calculates the amounts automatically at posting
- D. Run the Create G/L Acct. Journal Lines action a second time to populate the amounts
Show answer
Correct answer: B
The documented process is to export the journal table to Excel, manually enter the posting and balancing account amounts from the legacy system, then import and apply that data back into the journal before posting. Posting with blank amounts, deleting and starting over, or rerunning the same action will not populate the figures.
5. Before a person can be set up as a user inside Business Central online, where must their account first exist?
- A. The Business Central Users page, created manually by a functional consultant
- B. The on-premises Active Directory domain controller
- C. A configuration package imported through RapidStart Services
- D. The Microsoft 365 admin center
Show answer
Correct answer: D
Business Central online user accounts must first be created in the Microsoft 365 admin center; they are then imported into Business Central either automatically at first sign-in or by an admin running Update Users from Microsoft 365. Active Directory applies to on-premises deployments, not online. Configuration packages migrate business data, not identity accounts.

6. A developer is deciding between an RDL layout and a Word layout for a customer-facing sales invoice report that is emailed automatically after posting. Which factor should push the decision toward a Word layout?
- A. Word layouts support more report actions in the ribbon than RDLC
- B. RDLC layouts are reserved for internal reports and are not a valid option for document reports
- C. RDL layouts run in an untrusted sandbox app domain that lives just for the current invocation, which can slow UI-related actions like sending email, compared to Word
- D. Word layouts are the sole layout type that supports emailing a posted document
Show answer
Correct answer: C
Microsoft's guidance states that RDL layouts can result in slower performance for document reports on UI-related actions like sending emails, compared to Word layouts, because RDL layouts run in an untrusted sandbox app domain that only lives for the current invocation. Word layouts are not required for emailing in general, and RDLC layouts are fully usable for document reports, just not the recommended choice here.
7. A consultant uses Get Related Tables in the Configuration Worksheet after adding the Customer table to a configuration package. The Location table is not automatically added. What is the most likely reason?
- A. Get Related Tables skips conditionally related tables; Location relates to Customer conditionally, based on whether Location Code is filled in
- B. The Location table has already been added to a different configuration package
- C. The Location table does not support configuration packages
- D. The Exclude Configuration Tables checkbox controls whether Location is added as a related table
Show answer
Correct answer: A
Related tables are not added with Get Related Tables when the relation is conditional. Location relates to Customer only conditionally, namely if the Location Code field in the Customer table is filled in. This has nothing to do with other packages, table support, or the Exclude Configuration Tables checkbox, which controls configuration questionnaire, template, and worksheet tables instead.
8. An administrator is setting up a recurring job queue entry and is considering a 5-minute recurrence interval. What does Microsoft recommend?
- A. Use the shortest interval technically possible to keep data as current as possible
- B. 5-minute intervals are reserved for job queue entries running codeunits, not reports
- C. Consider whether a larger interval, such as 15 minutes or once an hour, would work instead, since frequent recurring jobs can affect performance
- D. Recurring intervals shorter than 10 minutes are automatically rejected by Business Central
Show answer
Correct answer: C
Microsoft's guidance for recurring job queues is to try to set the largest time interval you reasonably can, since recurring job queues can affect performance, considering factors like how many people work in the affected area and how long a single run takes. Business Central does not enforce a hard minimum interval or restrict short intervals to codeunits only.
9. A customer migrating from QuickBooks Online has a sales invoice for $500 with a $300 payment already applied. After running the QuickBooks Online Data Migration extension, what should the consultant expect for that invoice?
- A. Business Central migrates the full $500 invoice amount; the $300 partial payment is not migrated and must be handled manually
- B. Business Central migrates just the $200 outstanding balance as the invoice amount
- C. The invoice is skipped entirely because it has a partial payment
- D. Business Central migrates the $500 invoice and automatically recreates the $300 payment as a separate posted entry
Show answer
Correct answer: A
The QuickBooks Online Data Migration extension migrates only full amounts on sales and purchase documents; it does not update partially paid amounts, so a $500 invoice migrates as $500 regardless of the $300 already paid, and partial payments must be applied manually before or after migration. It is not skipped, reduced to the net balance, or auto-recreated as a payment entry.
10. Which setting on a number series allows users to manually type in a number instead of automatically inserting the next number in the sequence?
- A. Allow Gaps in Nos.
- B. Default Nos.
- C. Starting Date
- D. Manual Nos.
Show answer
Correct answer: D
Turning on the Manual Nos. toggle on a number series lets users manually enter a number rather than having the next consecutive number inserted automatically. Allow Gaps in Nos. is unrelated to manual entry, Default Nos. controls automatic use of the series, and Starting Date defines which line of a series is active.

“I've implemented Business Central for several small clients but had never carefully compared general posting setup against specific posting groups side by side. The posting group questions closed real gaps. Passed on my first attempt.”
Hanna N.
MB-800 Certified
“The dimension setup and default dimension priority questions were way more detailed than I expected from a practice test, and matched the real exam almost exactly.”
Omar T.

“As someone who mostly handles sales and purchasing, the fixed asset depreciation and financial reporting questions filled real gaps between what I knew and what the exam actually tests.”
