Which command is used to specify time travel requirements in cloning?

1. AFTER and BEFORE

2. NOW and LATER

3. AT and BEFORE

4. TIME and DATE

The correct answer is: AT and BEFORE

The command used to specify time travel requirements in cloning is "AT" and "BEFORE." This is integral to Snowflake's time travel feature, which allows users to access historical data states at specific points in time. When you clone a table, schema, or database in Snowflake, you can use the "AT" clause to identify the exact timestamp you want to reference the state of the object at that moment. The "BEFORE" clause lets users indicate an earlier point in time, which can be useful if they want to capture data as it existed prior to a specific event or change. This capability is a powerful aspect of Snowflake's architecture, enabling data versioning and recovery operations, as well as facilitating audits and testing scenarios. Thus, being able to specify time travel requirements accurately using these terms allows for precise control over data states during the cloning process.
