問題 #703
Which copy INTO command outputs the data into one file?
答案：B
解題說明：
The COPY INTO command in Snowflake can be configured to output data into a single file by setting the MAX_FILE_NUMBER option to 1. This option limits the number of files generated by the command, ensuring that only one file is created regardless of the amount of data being exported.

問題 #704
Which data protection feature should only be used when all other data recovery options have been attempted?
答案：C
解題說明：
The Fail-safe feature in Snowflake is the last-resort data recovery option that should only be used when all other options, such as Time Travel or Cloning, have been exhausted. Fail-safe provides a 7-day recovery period after the Time Travel window has expired but requires Snowflake Support intervention for data recovery. It is intended for disaster recovery and carries additional storage costs.
問題 #705
Which Snowflake feature can be used to find sensitive data in a table or column?
答案：D
解題說明：
Data classification in Snowflake is a feature that allows organizations to identify and categorize data stored in tables or columns based on its sensitivity level or content type. This feature can be used to find sensitive data within the database by classifying data as confidential, personal, public, etc., making it easier to apply appropriate security measures, such as masking policies or row-level security, to protect sensitive information.
