SnowPro Core Certification — Question 432

Which statement is true of zero-copy cloning?

Answer options

• A. It increases storage costs as cloning a table requires storing its data twice
• B. A cloned table includes the load history of the original source
• C. It is licensed as an additional Snowflake feature
• D. All micro-partitions between the original and cloned tables are fully shared

Correct answer: D

Explanation

The correct answer is D because zero-copy cloning allows the original and cloned tables to share micro-partitions, preventing the need for duplicate storage. Option A is incorrect since zero-copy cloning does not increase storage costs; option B is wrong as the cloned table does not retain load history; and option C is false because zero-copy cloning is included in the standard Snowflake offering without additional licensing.
