Answer: Time Travel

The question asks about Snowflake Continuous Data Protection (CDP) features used for maintaining historical data. Time Travel (D) is the correct answer because it allows users to access historical data within a configurable retention period (1-90 days) for purposes like querying, cloning, or restoring data. Fail-safe (B) is incorrect because it's a 7-day emergency backup only accessible by Snowflake support, not for user-driven historical data maintenance. Access control (A) and Network policies (C) are security features unrelated to historical data management. The community discussion confirms this with 100% consensus on D and explanations that Time Travel is user-accessible while Fail-safe is support-only.
