Question 90
The Query Processing Layer can run multiple compute clusters (virtual warehouses) simultaneously. Which statement is true regarding how the compute clusters access data?
- A Each virtual warehouse gets a complete copy of all data.
- B Each virtual warehouse gets a portion of the data.
- C Each virtual warehouse accesses the same shared data.
Reveal correct answer
Correct answer: C
Explanation
Snowflake stores data similarly to a shared-disk architecture, i.e., the data is shared. But it also allows for using several compute engines on the same shared data, each with its own memory and processing capabilities. https://docs.snowflake.com/en/user-guide/intro-key-concepts#snowflake-architectureDiscussion
