SnowPro Core Certification — Question 1094

How does Snowflake utilize clustering information to improve query performance?

Answer options

• A. It prunes unnecessary micro-partitions based on clustering metadata.
• B. It compresses the data within micro-partitions for faster querying.
• C. It automatically allocates additional resources to improve query execution.
• D. It organizes clustering information to speed-up data retrieval from storage.

Correct answer: A

Explanation

The correct answer is A because Snowflake leverages clustering metadata to eliminate unnecessary micro-partitions, which directly enhances query performance by reducing the amount of data scanned. Options B and C are incorrect as they do not accurately describe how clustering information is used for performance improvements, and option D, while related, does not specifically address the pruning aspect that is crucial for query efficiency.
