The answer is that records with empty email fields will remain as unmatched profiles. This outcome occurs because the unification process relies on an exact match rule using the email field, and when that field is empty, there is no data to compare against existing CRM records. In Microsoft Dynamics 365, matching rules require non-empty values to establish a link; an empty email simply cannot satisfy the exact match condition, so the record is left as a separate, unmatched profile rather than being merged or causing an error. On the MB-910 exam, this scenario tests your understanding of how missing data affects data unification in Customer Insights, often appearing as a trap where candidates assume empty fields cause errors or are automatically deleted. A common memory tip is to think of matching rules like a key: if the keyhole (email field) is empty, the key has nothing to turn, so the door stays closed—empty fields never match, they just stay unmatched.

Correct answer & explanation
✓
They will remain as unmatched profiles
Since the only matching rule uses exact match on email, records with empty email will not match any CRM record and will remain unmatched as separate profiles. Option C is correct. Option A is wrong because empty fields don't cause errors. Option B is wrong because match requires non-empty. Option D is wrong because they are not deleted.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
