Historical data is no longer available for querying.

• A. True
• B. False
• C. It depends on retention
• D. Not specified

Answer: (A)

Historical data availability for querying is governed by time travel retention. Snowflake keeps past data versions only for a defined period. Within that retention window you can query historical states (for example, with AS OF or AT clauses). Once that window expires, those historical states are no longer accessible for querying. The extra protection via fail-safe exists for recovery by Snowflake personnel, not for user queries, and it does not extend the queryability window. So the statement is true because historical data is not indefinitely queryable; its availability is limited by the configured retention period.
