Answers
D.
All virtual warehouses share the same compute resources so performance degradation of one warehouse can significantly affect all the other warehouses.
Suggested answer: C

Explanation:

A virtual warehouse in Snowflake is an independent compute cluster that performs data processing tasks such as executing SQL queries. Each virtual warehouse is dynamically allocated by Snowflake from the cloud provider's resources and does not share compute resources with other warehouses. This architecture ensures that the performance of one warehouse does not impact the performance of another. Adjusting the size of a virtual warehouse affects its computational power by increasing or decreasing the number of compute nodes, which can improve the performance of data processing tasks depending on the workload.
