1. Question 1Configure financials

   A controller wants Business Central to reject any general journal line dated before the first day of the current fiscal year. Which General Ledger Setup field enforces this?

   • AAllow Posting FromCorrect
   • BAllow Posting To
   • CRegister Time
   • DLCY Code
   ✓ Correct answer: A

   General Ledger Setup exposes an allowed posting date range. Any line dated earlier than Allow Posting From is blocked at posting time, which is how companies lock prior fiscal years from further entries.

   Why the other options are wrong

   • BAllow Posting To restricts the latest allowed date, not the earliest.
   • CRegister Time is a logging value, not a posting date restriction.
   • DLCY Code identifies the local currency, unrelated to date validation.
2. Question 2Configure financials

   A consultant needs a chart of accounts row that shows 'Total Liabilities' as the sum of every account between the 'Liabilities' Begin-Total row and this row, without listing individual account numbers. What must this row's Account Type be?

   • ABegin-Total
   • BEnd-TotalCorrect
   • CHeading
   • DPosting
   ✓ Correct answer: B

   This avoids needing an explicit Totaling filter, since the range is implicitly defined by the paired Begin-Total and End-Total rows surrounding the underlying posting accounts.

   Why the other options are wrong

   • ABegin-Total only marks where the range starts; it does not itself display the summed total.
   • CHeading carries no balance at all and cannot sum anything.
   • DPosting accounts hold individual transactions rather than a summed range.
3. Question 3Configure financials

   An accountant wants a single recurring line to split its amount across five cost center dimension values, each at a fixed percentage. Which Business Central feature works with the Balance recurring method to achieve this?

   • APayment Terms
   • BNumber Series
   • CAllocation KeysCorrect
   • DPosting Groups
   ✓ Correct answer: C

   When a recurring line uses the Balance method, an allocation key can be attached to spread the resulting balance across several cost centers according to fixed percentages set up on the key.

   Why the other options are wrong

   • APayment Terms controls due dates and discounts on customer or vendor documents, unrelated to allocations.
   • BNumber Series controls document numbering, not how an amount is distributed.
   • DPosting Groups determine G/L accounts for transactions, not how a single amount is split across dimensions.
4. Question 4Configure financials

   A company purchases a delivery truck as a single item that will be tracked, depreciated, and reported on as one unit. Which FA card role applies to this truck?

   • AMain AssetCorrect
   • BComponent
   • CDepreciation Book
   • DFA Subclass
   ✓ Correct answer: A

   A truck acquired and reported as one whole unit is set up as a Main Asset, as opposed to being a component of some other asset.

   Why the other options are wrong

   • BComponent describes an asset that belongs to and rolls up under a separate main asset, not a standalone unit.
   • CDepreciation Book defines depreciation rules, it is not an FA card role.
   • DFA Subclass is a category grouping, not a card role like main asset or component.
5. Question 5Perform Business Central operations

   A salesperson is discussing a potential sale with a prospective customer, including price and delivery expectations, but the customer has not yet committed to buying. Which document should be created?

   • ASales QuoteCorrect
   • BSales Order
   • CBlanket Sales Order
   • DSales Invoice
   ✓ Correct answer: A

   A Sales Quote records preliminary terms offered to a prospective customer before a commitment is made; it does not affect inventory availability or the customer ledger and can later be converted to an order or invoice.

   Why the other options are wrong

   • BA Sales Order represents a firm commitment to sell, not a preliminary offer.
   • CA Blanket Sales Order is a long-term agreement released into multiple orders, not a one-time preliminary offer.
   • DA Sales Invoice records and posts a bill to the customer, not a preliminary negotiation.
6. Question 6Perform Business Central operations

   Before prepayment invoices can be posted for sales orders, what must be configured in Sales & Receivables Setup?

   • AA default shipping agent
   • BA default salesperson code
   • CA default combine-shipments option
   • DPrepayment G/L accounts and VAT setupCorrect
   ✓ Correct answer: D

   Business Central needs to know which accounts receive the prepayment amounts and how VAT applies to them, so these accounts must be set up in Sales & Receivables Setup before a prepayment invoice can be posted from a sales order.

   Why the other options are wrong

   • AA default shipping agent affects delivery, not the ability to post a deposit invoice.
   • BA default salesperson code is used for reporting and commissions, unrelated to prepayment posting.
   • CCombine-shipments settings affect invoice consolidation, not prepayment invoicing.
7. Question 7Perform Business Central operations

   A van with a book value of 5,000 is sold for 6,000. What does Business Central post automatically when the disposal is entered?

   • ANo automatic G/L entry is created
   • BA 1,000 gain posted to the Gains on Disposal accountCorrect
   • CA 1,000 loss posted to the Losses on Disposal account
   • DA 6,000 credit to Accumulated Depreciation only
   ✓ Correct answer: B

   Business Central automatically calculates gain or loss as sales amount minus book value at disposal and posts it to the FA Posting Group's Gains Acc. on Disposal when the result is positive.

   Why the other options are wrong

   • AA G/L entry is created automatically for both the disposal and the resulting gain or loss.
   • CA loss would only be posted if the sales amount were below the book value.
   • DAccumulated Depreciation is cleared as part of disposal, but the gain is posted separately, not folded into that account alone.
8. Question 8Configure sales and purchasing

   Which of the following can differ between an item's general settings and its stockkeeping unit at a specific location?

   • AThe item's number
   • BThe item's base unit of measure
   • CThe item's item category
   • DReorder policy and safety stock quantityCorrect
   ✓ Correct answer: D

   A stockkeeping unit exists precisely to let replenishment-related settings differ per location, while identity fields like the item number stay the same everywhere.

   Why the other options are wrong

   • AThe item number stays the same across all of its stockkeeping units at different locations.
   • BBase unit of measure is defined once at the item level and is not overridden per location.
   • CItem category is a classification set at the item level, not overridden per location.
9. Question 9Set up Business Central

   A consultant exports a configuration package to Excel, edits several rows offline, and now wants those changes reflected back in Business Central before applying the package. What should the consultant do next?

   • ACreate a new company and import there
   • BRename the Excel file to match the table
   • CImport the edited file back into the packageCorrect
   • DPost the changes through a general journal
   ✓ Correct answer: C

   After editing exported package data offline, the consultant imports the updated Excel file into the package, replacing its staged data, and only then applies the package to write the changes into Business Central's tables.

   Why the other options are wrong

   • ACreating a new company is unnecessary and does not bring the edited data into the existing one.
   • BRenaming the file has no effect on how Business Central reads its content.
   • DA general journal posts financial transactions, it is not how configuration package data is loaded.
10. Question 10Set up Business Central

    You need to add a new employee to Business Central so they can sign in with their Microsoft 365 credentials. Which page do you use to create the user record?

    • AUsers pageCorrect
    • BPermission Sets page
    • CWorkflow User Groups page
    • DChange Log Setup page
    ✓ Correct answer: A

    The Users page is where an administrator creates a new user record, links it to a Microsoft 365 identity, and sets its license type and state before granting any access.

    Why the other options are wrong

    • BPermission Sets defines table-level access rules, it is not where user records are created.
    • CWorkflow User Groups groups existing users for approval routing, it does not create new users.
    • DChange Log Setup configures data-change logging, unrelated to creating user records.
