MB-910 Describe Dynamics 365 Customer Insights Practice Question
This MB-910 practice question tests your understanding of describe dynamics 365 customer insights. 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.
You are a data analyst for a multinational retail company. The company uses Dynamics 365 Customer Insights to manage customer data from various sources including online store, physical store transactions, and a loyalty program. The data is ingested daily. Recently, the marketing team reported that the segment 'High Spend Customers' (customers with total purchase amount > $10,000 in the last year) is showing incorrect numbers. Upon investigation, you find that some customers who have spent over $10,000 are not included in the segment, while some with lower spend are included. You suspect the issue is related to data freshness or the measure definition. The segment is based on a measure named 'TotalSpendLastYear' which is calculated from the 'Transaction' activity. The measure is set to refresh daily. The segment is set to refresh on demand. The data sources are refreshed automatically every night. What should you do first to troubleshoot the issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Manually trigger a refresh of the segment to ensure it uses the latest measure data
Option C is correct because the segment is set to refresh 'on demand,' meaning it does not automatically update when the underlying measure or data sources refresh. Even though the measure 'TotalSpendLastYear' refreshes daily and data sources refresh nightly, the segment itself may still be using stale measure data. Manually triggering a segment refresh forces it to re-evaluate the measure's current values, ensuring customers who now meet the $10,000 threshold are included and those who no longer qualify are excluded.
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.
✗
Modify the measure definition to use a different aggregation
Why it's wrong here
The measure definition appears correct; no need to change yet.
✗
Delete and recreate the segment with the same conditions
Why it's wrong here
Unnecessary step; refresh is simpler.
✓
Manually trigger a refresh of the segment to ensure it uses the latest measure data
Why this is correct
Segment may be using stale measure values.
Clue confirmation
The clue word "first" in the question point toward this answer.

✗
Re-ingest all transaction data from the source systems
Why it's wrong here
Data is ingested daily; re-ingesting won't help if segment is not refreshing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume because data sources and measures refresh automatically, the segment must also be up-to-date, but Microsoft explicitly tests the distinction between measure refresh schedules and segment refresh schedules, where 'on demand' segments require manual intervention to reflect current data.
Detailed technical explanation
How to think about this question
In Dynamics 365 Customer Insights, measures are computed independently from segments and can have their own refresh schedules. A segment that is set to 'on demand' refresh will only evaluate the latest measure values when explicitly triggered; otherwise, it retains the results from its last refresh. This separation allows for efficient processing but can lead to discrepancies if the segment refresh is not aligned with measure refreshes. In real-world scenarios, analysts often schedule segment refreshes to run after measure refreshes to avoid such mismatches.

Eliminate answers that are true in general but not in this case.
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.
