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 file types are not included in the scan rule set
Purview uses scan rule sets to determine which file types to scan and apply classifications. If the file type is not included in the scan rule set, those files will be skipped during scanning, leading to no classification. Option A is incorrect because if the storage account were not registered, no files would be scanned at all. Option B is incorrect because Parquet files are supported and can be classified. Option C is incorrect because if classification rules were disabled, no files would be classified, not just some.
