When resizing a multi-cluster warehouse, which clusters are resized?

• A. Clusters that started after the warehouse is resized
• B. All of them
• C. Clusters that are running
• D. None

Answer: (B)

In a multi-cluster warehouse, the size you set is applied uniformly to every cluster that belongs to that warehouse. A multi-cluster warehouse is designed to provide high concurrency by spinning up multiple clusters, all of which share the same size setting. When you resize, Snowflake updates the compute power of each cluster to the new size so performance remains consistent across the entire warehouse. The min/max cluster controls are about how many clusters can run, not about which clusters get resized, and resizing doesn’t target only clusters that are running or those created later. So the change applies to all clusters in that warehouse.
