Selected Answer: A
A - Using Trunc(ID_NUMBER, -6) we reduce the cardinality of the column by turning the last 6 digits of the ID to zeros https://docs.snowflake.com/fr/sql-reference/functions/trunc

Selected Answer: A
A. As another example, you can truncate a number to fewer significant digits by using the TRUNC functions and a negative value for the scale (e.g. TRUNC(123456789, -5)).
