Show Suggested Answer

Suggested Answer: C

Effective pruning in Snowflake relies on the organization of data within micro-partitions. By using an ORDER BY clause with clustering keys when loading data into the reporting tables, Snowflake can better organize the data within micro-partitions. This organization allows Snowflake to skip over irrelevant micro-partitions during a query, thus improving query performance and reducing the amount of data scanned12.

I wouldn't rely on Option C. Just because the user has privileges, doesn't mean the data will be automatically masked for other users. Better safe than sorry, go with A.

Option A is the correct answer. Unmasked data will be loaded into the new column, as the user has the appropriate privileges to see the unmasked data.
