Answer: by executing a Data Factory pipeline

## Explanation In Microsoft Purview, lineage data can be populated through multiple methods, but the specific scenario described in the question indicates that the lineage is populated **by executing a Data Factory pipeline**. ### Why Option C is Correct - **Azure Data Factory Integration**: Microsoft Purview has native integration with Azure Data Factory that automatically captures and pushes lineage information when Data Factory pipelines execute. - **Automated Lineage Collection**: When a Data Factory pipeline processes data (such as reading from a source, transforming it, and writing to a destination like a CSV file), the lineage metadata is automatically collected and sent to Purview. - **Real-time Lineage Tracking**: This method provides automated, real-time lineage tracking without manual intervention, ensuring accurate and up-to-date lineage information. ### Why Other Options Are Not Suitable - **Option A (manually)**: Manual lineage population is possible in Purview but is time-consuming, error-prone, and doesn't scale well for dynamic data environments. It's not the optimal method for automated lineage collection. - **Option B (by scanning data stores)**: While Purview can scan data stores to discover assets and schema information, scanning alone doesn't capture the detailed data movement and transformation lineage that occurs during pipeline executions. ### Best Practices Consideration For comprehensive data governance in Azure environments, leveraging the native integration between Azure Data Factory and Microsoft Purview is the recommended approach. This ensures: - Automated lineage capture without additional development effort - Accurate tracking of data transformations and movements - Real-time lineage updates as pipelines execute - Reduced manual maintenance overhead The exhibit referenced in the question would typically show a lineage diagram with Data Factory pipeline components, confirming that pipeline execution is the source of the lineage data.
