Correct answer & explanation
✓
Combine exact and fuzzy matching for better coverage
Combining exact and fuzzy matching in Dynamics 365 Customer Insights allows the system to identify both identical records (exact match) and near-duplicates with minor variations like typos or abbreviations (fuzzy match), improving deduplication coverage without sacrificing precision. This hybrid approach is a best practice to balance accuracy and recall when configuring match rules.
