}You are configuring Microsoft Purview to scan an Azure Data Explorer (ADX) cluster. You define the JSON shown in the exhibit. However, the scan fails with an authentication error. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The ADX cluster does not have a managed identity enabled for Purview.
Purview requires a system-assigned managed identity (or user-assigned) to be enabled on the ADX cluster and granted permissions. Option A (firewall) could be a cause, but the error is authentication specifically. Option B (region mismatch) is not a common issue. Option D (incorrect database) would cause a different error.
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 ADX cluster is behind a firewall and Purview cannot connect.
Why it's wrong here
Firewall would cause a connection error, not authentication.
- ✗
The database name in the scan configuration is incorrect.
Why it's wrong here
Incorrect database would cause a 'database not found' error.
- ✓
The ADX cluster does not have a managed identity enabled for Purview.
Why this is correct
Purview uses managed identity for authentication; it must be enabled.
- ✗
The region of the ADX cluster does not match the Purview account region.
Why it's wrong here
Region mismatch does not cause authentication errors.
