Answer: Columnar, Compressed

The question asks about the two internal storage formats Snowflake uses in cloud storage. Snowflake stores data internally in a columnar format (B) because it's optimized for analytical queries, allowing efficient access to specific columns. Additionally, Snowflake automatically compresses (E) the data to reduce storage costs and improve performance. The community discussion shows 100% consensus on BE, with multiple upvoted comments confirming these as the correct answers. Options A (Key-value), C (Graph), and D (Document) are incorrect as they represent other database storage paradigms not used internally by Snowflake for its core storage architecture.
