Which set of layers is typically associated with the Medallion Architecture for data management?

• A. Bronze, Gold, Silver
• B. Raw, Polished, Refined
• C. Bronze, Silver, Gold
• D. Bronze, Silver, Platinum

Answer: (C)

The main idea here is the three-stage data flow in the Medallion Architecture, where data moves from ingestion to refined analytics-ready data. The standard naming and progression are Bronze for raw ingested data, Silver for cleaned and enriched data, and Gold for business-ready datasets and aggregates. This sequence captures how data quality and usability improve at each step, making it the typical association you’ll see in practice.

Other naming options don’t match this established flow. Bronze, Gold, Silver would imply cleaning comes after the analytics layer, which isn’t how the architecture is designed. Raw, Polished, Refined uses nonstandard labels and doesn’t align with the conventional Bronze/Silver/Gold progression. Platinum is not part of the standard Medallion set, so Bronze, Silver, Platinum introduces an unfamiliar layer that isn’t typically used.
