The answer is that the WinRate measure calculates the percentage of won opportunities out of all closed opportunities. This is correct because WinRate in Dynamics 365 Sales is designed to assess sales team effectiveness by focusing only on opportunities that have reached a final outcome—either won or lost—while deliberately excluding open opportunities, which have not yet been resolved. On the Microsoft Dynamics 365 Fundamentals CRM MB-910 exam, this concept tests your understanding of key sales analytics metrics and how they filter data to provide meaningful insights; a common trap is assuming WinRate includes open opportunities or all opportunities regardless of status. To remember this, think of the word “closed” as the gatekeeper: only deals that have crossed the finish line count, so WinRate = (Won) / (Won + Lost), ignoring everything still in play.

Exhibit
Refer to the exhibit. The following is a snippet from a Sales Analytics report DAX measure:
WinRate = DIVIDE(
CALCULATE(COUNTROWS(Opportunity), Opportunity[Status] = "Won"),
CALCULATE(COUNTROWS(Opportunity), Opportunity[Status] IN {"Won", "Lost"})
)
Based on the exhibit, what does the WinRate measure calculate?
Refer to the exhibit. The following is a snippet from a Sales Analytics report DAX measure:
WinRate = DIVIDE(
CALCULATE(COUNTROWS(Opportunity), Opportunity[Status] = "Won"),
CALCULATE(COUNTROWS(Opportunity), Opportunity[Status] IN {"Won", "Lost"})
)
A
The total count of won opportunities
Why wrong: It returns a percentage, not a count.
B
The percentage of won opportunities out of all opportunities including open
Why wrong: Open opportunities are not included in the denominator.
C
The percentage of won opportunities out of all closed opportunities
The denominator is Won + Lost, which are closed opportunities.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The percentage of won opportunities out of all closed opportunities
WinRate in Dynamics 365 Sales measures the percentage of won opportunities out of all closed opportunities (both won and lost). This metric excludes open opportunities because they have not yet reached a final outcome, providing a clear view of sales team effectiveness in closing deals that have been fully pursued.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse WinRate with the win/loss ratio (Option D) or mistakenly include open opportunities (Option B), because they think a 'rate' should include all opportunities in the pipeline, but the correct definition specifically excludes open deals to measure only closed outcomes.
Detailed technical explanation
How to think about this question
Under the hood, Dynamics 365 Sales calculates WinRate by dividing the number of opportunities with a status of 'Won' by the total number of opportunities with a status of either 'Won' or 'Lost', then multiplying by 100. Open opportunities (status 'Open') are excluded because they lack a final disposition. This metric is often used in sales dashboards to evaluate pipeline health and rep performance, and it can be filtered by date ranges or sales teams for more granular analysis.

TExam Day Tips
→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.
