Suggested answer: A, B

Explanation:

Managing Data Files

Staged files can be deleted from a Snowflake stage (user stage, table stage, or named stage) using the following methods:

· Files that were loaded successfully can be deleted from the stage during a load by specifying the PURGE copy option in the COPY INTO <table> command.

· After the load completes, use the REMOVE command to remove the files in the stage.

Removing files ensures they aren't inadvertently loaded again. It also improves load performance, because it reduces the number of files that COPY commands must scan to verify whether existing files in a stage were loaded already.
