MB-910 Describe Dynamics 365 Customer Insights Practice Question
You are a business analyst for a nonprofit organization that uses Dynamics 365 Customer Insights. They have donor data from a fundraising system and event attendance data from a separate system. They want to create a single view of each donor. After importing both data sources, you run the data unification process. However, you notice that some donors who appear in both systems are being created as separate profiles instead of being merged. What is the most likely cause?
⚠ Common exam trap
Test-takers frequently assume the issue is a data import error (Option B) or a sequencing problem (Option D), but the core technical cause is the absence of properly configured deduplication rules, which is a common oversight in Customer Insights implementations.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The deduplication rules are not configured to match on common fields like email.
The data unification process in Dynamics 365 Customer Insights relies on deduplication rules to identify and merge matching profiles. If these rules are not configured to match on common fields such as email address, the system will treat records from different sources as separate profiles, even if they represent the same donor. Without proper matching conditions, the unification step cannot link the records, resulting in duplicate profiles.
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 profiles were enriched with external data.
Why it's wrong here
Enrichment doesn't prevent merging.
- ✗
The data sources were not imported correctly.
Why it's wrong here
Data is present, just not merged.
- ✓
The deduplication rules are not configured to match on common fields like email.
Why this is correct
Without proper rules, duplicates won't merge.
- ✗
The segment was created before unification.
Why it's wrong here
Segments don't affect merging.
