What optional properties can a Snowflake user set when creating a virtual warehouse? (Select TWO).
Answer : A, D
When creating a virtual warehouse in Snowflake, users have the option to set several properties to manage its behavior and resource usage. Two of these optional properties are Auto-suspend and Resource monitor.
Auto-suspend: This property defines the period of inactivity after which the warehouse will automatically suspend. This helps in managing costs by stopping the warehouse when it is not in use.
CREATE WAREHOUSE my_warehouse
WITH WAREHOUSE_SIZE = 'XSMALL'
AUTO_SUSPEND = 300; -- Auto-suspend after 5 minutes of inactivity
Resource monitor: Users can assign a resource monitor to a warehouse to control and limit the amount of credit usage. Resource monitors help in setting quotas and alerts for warehouse usage.
CREATE WAREHOUSE my_warehouse
WITH WAREHOUSE_SIZE = 'XSMALL'
RESOURCE_MONITOR = 'my_resource_monitor';

What is the purpose of the use of the VALIDATE command?
Answer : D
The VALIDATE command in Snowflake is used to check for errors that occurred during the execution of a COPY INTO <table> statement. This command helps users identify and resolve data loading issues.

COPY INTO my_table
FROM @my_stage
FILE_FORMAT = (FORMAT_NAME = 'my_format');
Validate the Load: Use the VALIDATE function to see if there were any errors during the data load.
SELECT *
FROM TABLE(VALIDATE(my_table, JOB_ID => 'my_copy_job_id'));
Review Errors: The VALIDATE function will return details about any errors that occurred, such as parsing errors or data type mismatches.

How can a data provider validate that a secure view is configured to display only the data the provider wishes to expose?
Answer : B
The most effective way for a data provider to validate secure view configurations is to create a data share for a test data consumer account. This method allows the provider to review and confirm that only the intended data is accessible in the secure view. Secure views are designed to mask or restrict data visibility, so creating a test share replicates the consumer's experience and ensures data security before sharing with actual consumers.
