Snowflake SnowPro Certification Practice Test

When can you expect a warehouse to be auto-suspended?

1. When a certain number of queries have failed

2. When there are no active queries or tasks running

3. After a specific amount of data has been processed

4. When the credit balance is low

The correct answer is: When there are no active queries or tasks running

A warehouse in Snowflake is designed to optimize cost and resources, and its auto-suspension feature is pivotal in maintaining this balance. The auto-suspension process activates when there are no active queries or tasks running. Once the system detects that all operations have concluded, the warehouse can automatically suspend to prevent unnecessary resource usage and associated costs. This intelligent management ensures that users only pay for the compute resources they actually utilize when executing queries or performing tasks. In contrast, the other options do not align with the auto-suspension triggers for a warehouse. For instance, a warehouse does not suspend based on failed queries; instead, it focuses on active usage. The volume of data processed also does not directly influence suspension; rather, it is concerned with ongoing activity. Lastly, while a low credit balance signifies that costs may need to be monitored, it does not directly affect the suspension of the warehouse based on query activity. The main operative factor is the presence or absence of active operations within the warehouse.
