Databricks Certified Data Engineer Associate — Question 128

A data engineering team is using Kafka to capture event data and then ingest it into Databricks. The team wants to be able to see these historical events. Medallion architecture is already in place. The team wants to be mindful of costs.

Where should this historical event data be stored?

Answer options

• A. Gold
• B. Silver
• C. Bronze
• D. Raw layer

Correct answer: C

Explanation

The Bronze layer is designed to store raw, unrefined data, making it suitable for historical event data that needs to be retained at a lower cost. The Gold layer is for highly processed data used for analytics, while the Silver layer contains refined data, which may incur higher costs. The Raw layer is not a standard term in the Medallion architecture, making it less appropriate for this context.
