The correct answer is that the invoice is posted with a zero USD amount, causing an imbalance. This happens because Dynamics 365 Finance requires a valid exchange rate to convert a foreign currency transaction into the general ledger’s accounting currency; when no rate is specified, the system defaults to zero, which results in a USD value of zero for the invoice line, leaving the ledger out of balance. On the MB-920 exam, this scenario tests your understanding of dual-currency posting mechanics and the critical role of exchange rate configuration—a common trap is assuming the system will reject the entry or auto-correct later, but it posts the zero-rate transaction immediately. Remember the memory tip: “No rate, zero state”—if the exchange rate is missing, the ledger amount goes to zero, creating an imbalance that must be manually corrected.
MB-920 Describe Dynamics 365 Finance Practice Question
This MB-920 practice question tests your understanding of describe dynamics 365 finance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A company uses Dynamics 365 Finance with dual-currency accounting. They have transactions in both USD and EUR. The general ledger is set to USD, but a user posts a vendor invoice in EUR without specifying an exchange rate. The system posts the invoice at a rate of 0. The next day, the exchange rate for EUR/USD is 1.10. What is the impact on the general ledger?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The invoice is posted with a zero USD amount, causing an imbalance.
Option C is correct because when the exchange rate is not provided, the system uses the default rate, which could be zero if not configured. The zero rate leads to a zero USD amount, causing an imbalance. The user must correct the invoice with the correct rate. Option A is wrong because the system does not automatically update the rate after posting. Option B is wrong because the system does not reject the invoice; it posts with zero. Option D is wrong because the exchange rate difference is not automatically calculated without a rate.
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.
✗
The system rejects the invoice due to a missing exchange rate.
Why it's wrong here
The system posts with a rate of zero; it does not reject.
✗
The system automatically updates the invoice using the next day's rate of 1.10.
Why it's wrong here
The system does not retroactively update posted invoices.
✓
The invoice is posted with a zero USD amount, causing an imbalance.
Why this is correct
Without a rate, the USD amount is zero, leading to an unbalanced entry.
Related concept
Read the scenario before looking for a memorised answer.
✗
The system posts the invoice and creates an exchange rate difference journal.
Why it's wrong here
Since the rate is zero, no exchange rate difference is recognized; the imbalance must be corrected manually.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
