The correct answer is that the KQL query calculates the average resolution time per owner for resolved cases. This is because the query filters the dataset to only include resolved cases, then groups the results by the case owner and applies the `avg()` aggregation function to the resolution time field, producing a mean duration rather than a sum or count. On the MB-910 exam, this question tests your ability to interpret KQL syntax in the context of Dynamics 365 Customer Service analytics, where common traps include confusing average with total resolution time or misidentifying the grouping field as priority instead of owner. A reliable memory tip is to focus on the `avg()` function and the `where` clause: if you see `avg()` and a filter for resolved status, you are always looking at an average per group, not a total or an open-case metric.

Refer to the exhibit.
KQL query:
Dynamics365Activity
| where ActivityType == "Case"
| where Status == "Resolved"
| summarize AvgResolutionTime = avg(ResolutionTime) by OwnerName
You are analyzing Dynamics 365 Customer Service performance. Based on the KQL query, what is being calculated?
Refer to the exhibit.
KQL query:
Dynamics365Activity
| where ActivityType == "Case"
| where Status == "Resolved"
| summarize AvgResolutionTime = avg(ResolutionTime) by OwnerName
A
Total resolution time per owner
Why wrong: Uses avg, not sum.
B
Average resolution time by priority
Why wrong: Not grouped by priority.
C
Number of open cases per owner
Why wrong: Filters resolved cases.
D
Average resolution time per owner for resolved cases
The query groups by OwnerName and averages ResolutionTime.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Average resolution time per owner for resolved cases
The query filters resolved cases and averages resolution time by owner. Option A is correct. Option B is wrong because it's average, not total. Option C is wrong because it's not by priority. Option D is wrong because it's not about open cases.
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
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 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.
