質問 # 608
What happens when a suspended virtual warehouse is resized in Snowflake?
正解：B
解説：
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.

A stream object will advance its offset when it is used in which statement?
正解：B
質問 # 610
How can a Snowflake user validate data that is unloaded using the COPY INTO <location> command?
正解：C
解説：
To validate data unloaded using the COPY INTO <location> command, a Snowflake user can use the VALIDATION_MODE parameter within the SQL statement to test the files for errors without loading them3.
質問 # 611
How can a 5 GB table be downloaded into a single file MOST efficiently?
正解：C
解説：
To download a 5 GB table into a single file most efficiently in Snowflake, you should set the SINGLE parameter to TRUE. This parameter ensures that the COPY INTO command outputs the result into a single file, regardless of the file size. This approach is more efficient than relying on the default MAX_FILE_SIZE setting, which would split the output into multiple files.

質問 # 612
A user wants to access files stored in a stage without authenticating into Snowflake. Which type of URL should be used?
正解：B
解説：
A Pre-signed URL should be used to access files stored in a Snowflake stage without requiring authentication into Snowflake. Pre-signed URLs are simple HTTPS URLs that provide temporary access to a file via a web browser, using a pre-signed access token.The expiration time for the access token is configurable, and this type of URL allows users or applications to directly access or download the files without needing to authenticate into Snowflake5.
