What is the name of the Snowflake-provided warehouse used for billing Automatic Clustering?

• A. CLUSTERING_BILLING
• B. AUTOMATIC_CLUSTERING
• C. SNOWFLAKE_WAREHOUSE
• D. AUTO_CLUSTER

Answer: (B)

Automatic clustering runs in a Snowflake-provided, dedicated compute warehouse named AUTOMATIC_CLUSTERING. This service warehouse carries out the background clustering work to optimize how data is stored in micro-partitions, and its usage (compute and billing) is tracked separately from your user warehouses. That makes AUTOMATIC_CLUSTERING the correct name you’d see associated with this feature’s billing. The other options don’t correspond to the official warehouse Snowflake provisions for automatic clustering.
