Which statement best describes Snowflake tables?
Snowflake tables are logical representations of the underlying physical data. This means that they provide a way to work with the data without directly interacting with the physical storage format. Unlike traditional databases where tables are tightly coupled to their physical storage, Snowflake uses micro-partitions and treats tables as an abstraction layer over that physical data. This allows for efficient data management and query performance without the need to understand or manage the underlying physical structure directly.
The best statement that describes Snowflake tables is Snowflake tables are logical representations of underlying physical data. Snowflake tables do not require that clustering keys be defined to perform optimally. However, defining clustering keys can improve the performance of queries that filter or sort the data. Snowflake tables can be owned by a user or by a role. Therefore, the correct answer is A. Snowflake tables are logical representations of underlying physical data.

A is correct
A is correct answer.

C seems correct too. Snowflake tables require clustering keys to perform optimally. Clustering keys help manage micro partitions for a table, which in turn helps in query performance by means of partition pruning.
