Snowflake SnowPro Certification Practice Test

Which of the following statements about Virtual Warehouses is true?

1. They require constant manual monitoring

2. They can be auto-suspended when not in use

3. They only support specific file types

4. They cannot be resized

The correct answer is: They can be auto-suspended when not in use

Virtual Warehouses in Snowflake are designed to optimize resource usage and costs. One of the key features is the ability to auto-suspend when they are not in use. This means that if a Virtual Warehouse is idle for a configured period, it will automatically suspend itself, effectively preventing unnecessary charges for compute costs. This automated feature allows businesses to manage their resources efficiently without the need for constant oversight, making it a flexible solution that adapitates to usage patterns. The other statements do not reflect the capabilities of Snowflake's Virtual Warehouses. They do not require manual monitoring, as the auto-suspend feature takes care of idle instances. Additionally, Virtual Warehouses are not limited to specific file types; they can process various types of data. Lastly, Virtual Warehouses can be resized dynamically based on the workload needs, allowing for greater flexibility in performance adjustments.
