Snowflake Certification Practice Test

True or False: Zero-Copy cloning allows real data provision for development without copying the data.

1. True

2. False

3. Only in certain editions

4. It depends on the data type.

The correct answer is: True

Zero-Copy Cloning is a significant feature of Snowflake that enables users to create clones of data without actually duplicating it on disk. This means that when a clone is created, it initially shares the same underlying data as the original, using a method called copy-on-write. This allows developers to work with real data in a development environment without incurring the storage costs or time associated with traditional data copying. The process is highly efficient because it preserves storage resources and provides immediate access to the data, ensuring that the cloned dataset is always in sync with the original until any modifications are made. Additionally, as changes are made to either the cloned or the original dataset, the non-modified data continues to be shared, and only the changes consume additional storage. Because of these characteristics, the statement claiming that Zero-Copy Cloning allows real data provision for development without copying the data is accurate, hence the correct answer is true. Other options suggest limitations or conditions that do not align with the core functionality of Zero-Copy Cloning as implemented in Snowflake.
