Answer: Silver tables contain less data than Bronze tables.

## Explanation In the Databricks Lakehouse architecture, the medallion architecture typically consists of three layers: 1. **Bronze layer**: Raw, unprocessed data ingested from source systems 2. **Silver layer**: Cleaned, validated, and enriched data 3. **Gold layer**: Aggregated, business-ready data for reporting and analytics **Why option D is correct**: - Silver tables contain **less data** than Bronze tables because during the transformation from Bronze to Silver: - Duplicate records are removed - Invalid or malformed data is filtered out - Data is deduplicated - Only relevant data is kept after cleaning **Why other options are incorrect**: - **Option A**: False - Silver tables contain MORE refined and cleaner data than Bronze tables - **Option B**: False - Aggregation typically happens in the Gold layer, not Silver. Silver focuses on cleaning and validation - **Option C**: False - Silver tables contain LESS data than Bronze tables due to data cleaning and filtering **Key insight**: The transformation from Bronze to Silver reduces data volume through data quality improvements, making Silver tables smaller but higher quality than their Bronze counterparts.
