Snowflake SnowPro Core Certification Exam Sample Questions (Q472-Q477):

NEW QUESTION # 472
In Snowflake, what allows users to perform recursive queries?

Answer: C

Explanation:
In Snowflake, the CONNECT BY clause allows users to perform recursive queries. Recursive queries are used to process hierarchical or tree-structured data, such as organizational charts or file systems. The CONNECT BY clause is used in conjunction with the START WITH clause to specify the starting point of the hierarchy and the relationship between parent and child rows.
Reference:
Snowflake Documentation: Hierarchical Queries


NEW QUESTION # 473
Which function will provide the proxy information needed to protect Snowsight?

Answer: A


NEW QUESTION # 474
Which commands can only be executed using SnowSQL? (Select TWO).

Answer: B,E

Explanation:
The LIST and PUT commands are specific to SnowSQL and cannot be executed in the web interface or other SQL clients. LIST is used to display the contents of a stage, and PUT is used to upload files to a stage. Reference: [COF-C02] SnowPro Core Certification Exam Study Guide


NEW QUESTION # 475
What happens when a suspended virtual warehouse is resized in Snowflake?

Answer: D

Explanation:
In Snowflake, resizing a virtual warehouse that is currently suspended does not immediately provision the new compute resources. Instead, the change in size is recorded, and the additional compute resources are provisioned when the warehouse is resumed. This means that the action of resizing a suspended warehouse does not cause it to resume operation automatically. The warehouse remains suspended until an explicit command to resume it is issued, or until it automatically resumes upon the next query execution that requires it.
This behavior allows for efficient management of compute resources, ensuring that credits are not consumed by a warehouse that is not in use, even if its size is adjusted while it is suspended.


NEW QUESTION # 476
Which table function will identify data that was loaded using COPY INTO <table> statements and also identify data loaded using Snowpipe?

Answer: B

Explanation:
The COPY_HISTORY table function in Snowflake is used to track data loading activities, including both manual COPY INTO <table> commands and automated data loading through Snowpipe. This function provides visibility into load operations, making it valuable for monitoring data ingestion, ensuring data integrity, and troubleshooting loading processes.
