COF-C02 · Question #336

For which use cases is running a virtual warehouse required? (Select TWO).

The correct answer is B. When loading data into a table C. When unloading data from a table. Virtual warehouses (compute clusters) are required for operations that involve data processing: loading data into a table (COPY INTO <table>) and unloading data from a table (COPY INTO <location>) both require active compute to read, transform, and write data.

Explanation

Virtual warehouses (compute clusters) are required for operations that involve data processing: loading data into a table (COPY INTO <table>) and unloading data from a table (COPY INTO <location>) both require active compute to read, transform, and write data. DDL operations like CREATE TABLE (A) are handled by Snowflake's cloud services layer and do not require a running warehouse. Similarly, metadata operations like SHOW commands (D) and LIST commands (E) are resolved entirely by the cloud services layer without consuming warehouse compute resources - they simply query Snowflake's internal metadata store.
