The answer is 14. This is correct because the total length of an account structure in Dynamics 365 Finance is calculated by summing the segment lengths of all active financial dimensions, including the main account. In this case, the main account length is 6, the department segment is 3, and the cost center segment is 5, giving a total of 6+3+5=14. On the Microsoft Dynamics 365 Fundamentals ERP MB-920 exam, this question tests your understanding of how account structures are built from segments, and a common trap is forgetting to include the main account in the total length calculation. A frequent mistake is adding extra characters or misreading the segment lengths from the exhibit. To remember this, use the mnemonic "Main Plus Dimensions" — always start with the main account length, then add each dimension segment exactly as shown, without any extra separators or padding.
MB-920 Describe Dynamics 365 Finance Practice Question
This MB-920 practice question tests your understanding of describe dynamics 365 finance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
14
Option C is correct. The main account length is 6, department segment length is 3, cost center segment length is 5. Total = 6+3+5 = 14. Option A is wrong because it omits the main account. Option B is wrong because it miscalculates. Option D is wrong because it adds extra characters.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Read the scenario before looking for a memorised answer.
✗
15
Why it's wrong here
15 is too high; the sum is 14.
✗
11
Why it's wrong here
11 is not the sum of the given lengths.
✗
8
Why it's wrong here
8 would be the sum of the two dimension segments only (3+5), but the main account is also required.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Variation 1. Refer to the exhibit. A journal entry in Dynamics 365 Finance shows a debit to account 1100-001-01 and offset to account 2100-002-02. The financial dimensions include Department=Sales and CostCenter=CC001. What is the purpose of this entry?
hard
A.Recording a customer payment
B.Recording a vendor payment
✓ C.Increasing cash and increasing a liability
D.Reclassifying a bank transaction
Why C: Account 1100 is typically Cash (asset). Account 2100 is typically Accounts Payable (liability). Debiting Cash and crediting AP does not make sense for payment. A debit to Cash (increase) and credit to AP (increase) is unusual; more likely it's a receipt from a vendor refund. But typical: debit Cash, credit AP means receiving cash and reducing liability? Actually debit Cash increases, credit AP increases liability. That would be a loan or refund. Option D matches: increasing cash and increasing liability (e.g., receiving a deposit).
