The correct answer is that the estimated revenue field was manually overridden with a negative value during data import. This happens because Microsoft Dynamics 365 allows users to directly edit the estimated revenue field on an opportunity, and when data is imported from a legacy system, a negative value can be written into that field if the source data contained a negative number or if the import mapping incorrectly set the value. On the MB-910 exam, this question tests your understanding of how opportunity revenue is calculated versus manually entered, and it often appears as a trap where learners confuse currency exchange rates or probability calculations with direct field overrides. A common mistake is assuming negative revenue comes from exchange rate fluctuations, but the system never auto-generates a negative figure from those factors. Remember the memory tip: if you see a negative estimated revenue, think "manual override, not math"—the system only goes negative when a user or import forces it.
MB-910 Practice Question: Explore the core capabilities of customer engagement apps in Dynamics 365
This MB-910 practice question tests your understanding of explore the core capabilities of customer engagement apps in dynamics 365. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 sales manager reports that the Opportunity record for a high-value deal shows a negative estimated revenue of -$15,000. The system currency is USD. The opportunity was created by importing data via a legacy integration. What is the most likely cause of this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The estimated revenue field was manually overridden with a negative value during data import.
Option C is correct because negative revenue in Dynamics 365 typically occurs when the estimated revenue is manually overridden with a negative value or calculated from negative quantity/price. Option A is wrong because currency exchange rates affect display but do not create negative values. Option B is wrong because revenue is not auto-calculated from close probability as negative. Option D is wrong because security roles do not affect revenue calculation.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 user does not have sufficient privileges to view positive revenue.
Why it's wrong here
Security privileges control read/write access but do not alter data values.
✓
The estimated revenue field was manually overridden with a negative value during data import.
Why this is correct
Manual override or import can set negative values if the source data contains negative numbers.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Authentication checks who the user is.
✗
The opportunity's close probability was set to more than 100%.
Why it's wrong here
Close probability is a percentage from 0 to 100% and does not affect revenue sign.
✗
The currency exchange rate for USD is inverted.
Why it's wrong here
Exchange rate inversion would not cause a negative revenue; it would affect the converted amount but not the base value.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related MB-910 questions on access control and AAA configuration.
