Which data store in Microsoft Fabric can store raw CSV files?

• A. Lakehouse
• B. Warehouse
• C. Eventhouse
• D. Azure Blob Storage

Answer: (A)

Raw CSV files fit best in a Lakehouse because it acts as the data lake–aware store in Fabric that can hold data in its native formats, including CSV, while also providing analytics-ready capabilities. You land the raw data in the lake storage underlying the Lakehouse and can later curate or transform it into structured tables if needed. A Warehouse, by contrast, is optimized for structured, prepared data and fast BI queries, not for storing raw files. Eventhouse focuses on streaming/event data, not general raw file landings. Azure Blob Storage is a general storage option, but within Fabric the data store designed for mixing raw data with analytics is the Lakehouse.
