MB-910 Describe Dynamics 365 Customer Insights Practice Question
An administrator notices that customer profiles in Dynamics 365 Customer Insights have duplicate records after data unification. What should they do to resolve this?
⚠ Common exam trap
Watch out — candidates often assume re-running unification (Option C) will fix duplicates, but without adjusting the deduplication rules, the same matching logic will produce identical duplicate results.

Correct answer & explanation
✓
Adjust the deduplication rules
Deduplication rules in Dynamics 365 Customer Insights define how the system identifies and merges duplicate records during data unification. If duplicates remain after unification, adjusting these rules—such as modifying match conditions, similarity thresholds, or priority order—allows the system to correctly consolidate duplicate customer profiles without losing data or requiring a full re-run.
