Your organization needs to implement a Microsoft Purview data classification solution that scans data in Microsoft 365, Azure SQL Database, and Amazon S3. Which Microsoft Purview feature should you use?
Microsoft Purview Data Map is the unified metadata backbone that discovers, classifies, and maps data across Microsoft 365, Azure SQL Database, and Amazon S3. It satisfies the multi-source scanning requirement by providing a single catalogue spanning on-premises, multicloud, and SaaS sources.
Why this answer
Microsoft Purview Data Map is the foundational metadata and scanning service that discovers and classifies data across sources including Microsoft 365, Azure SQL Database, and Amazon S3. It registers sources, runs scans, applies classification rules, and builds the data estate catalog that other Purview solutions consume. Because the requirement spans multi-cloud and on-prem sources, the Data Map is the correct feature.
Exam trap
MS-102 often tests the confusion between Data Map (discovery/catalog) and Information Protection (labeling/enforcement), so candidates pick labels when the scenario is really about multi-source scanning.
How to eliminate wrong answers
Option A is wrong because Data Loss Prevention enforces policies on data in motion/use within supported workloads and does not scan Amazon S3 or build a cross-cloud catalog. Option B is wrong because sensitivity labels classify and protect content primarily in Microsoft 365 and supported apps, not arbitrary external sources like S3. Option C is wrong because eDiscovery is a legal/HR workflow for identifying and preserving content for litigation, not a data classification scanning engine.
