Which command should be used to unload all the rows from a table into one or more files in a named stage?

正解：B

解説：
To unload data from a table into one or more files in a named stage, the COPY INTO <location> command should be used.

質問 # 606
What is a feature of column-level security in Snowflake?

正解：A

解説：
Column-level security in Snowflake is implemented through Role Access Policies. These policies allow administrators to control access to specific columns of a table or view based on the role of the user accessing the data. By applying a role access policy to a column, administrators can ensure that sensitive information remains secure, and only users with the appropriate roles can view or query the data in that column. This feature enhances the security model by providing fine-grained access control at the column level.
