Snowflake Certification Practice Test

What are two key features of Snowflake’s storage architecture?

1. Time Machine and Time Travel

2. Snapshot Cloning and Data Merger

3. Time Travel and Zero-Copy Cloning

4. Snapshot Cloning and Data Compression

The correct answer is: Time Travel and Zero-Copy Cloning

Snowflake’s storage architecture is designed with unique features that significantly enhance data management and accessibility, making the correct answer of Time Travel and Zero-Copy Cloning especially relevant. Time Travel allows users to access historical data and recover data that has been modified or deleted within a defined retention period. This feature is invaluable for operations that require data accuracy and recovery, such as auditing and compliance, allowing users to query their data as it existed at specific points in time. Zero-Copy Cloning is another critical feature that differentiates Snowflake’s storage capabilities. This allows users to create clones of tables, schemas, or databases without incurring additional storage costs. The process is instantaneous and does not require data duplication, enabling efficient management of data for testing or development purposes. This means that data can be manipulated without affecting the original dataset, facilitating agile data operations. While the other choices also include beneficial features of Snowflake, they do not compare in significance to the combined advantages provided by Time Travel and Zero-Copy Cloning in the context of storage architecture’s efficiency and versatility.
