The correct answer is B, as the Bronze layer is designed to store raw, unprocessed data ingested from streaming sources like Kafka. This layer serves as the initial landing zone before data is processed and moved to the Silver layer for further refinement. The Bronze layer is crucial for preserving the full, unprocessed history of data, making it an essential component of the Medallion Architecture. Understanding the distinct roles of the Bronze, Silver, and Gold layers is key to mastering data engineering concepts on the Databricks platform.
