Actual exam question for Snowflake's COF-C02 exam
Question #: 152
Topic #: 3
Which Snowflake mechanism is used to limit the number of micro-partitions scanned by a query?

Suggested Answer: C Vote an answer

Query pruning in Snowflake is the mechanism used to limit the number of micro-partitions scanned by a query. By analyzing the filters and conditions applied in a query, Snowflake can skip over micro-partitions that do not contain relevant data, thereby reducing the amount of data processed and improving query performance. This technique is particularly effective for large datasets and is a key component of Snowflake's performance optimization features.
