Answer: 30 Days

The correct answer is A (30 Days) based on Snowflake's official documentation and the strong community consensus. Snowflake automatically rotates its managed encryption keys every 30 days as a security best practice. The community discussion shows unanimous agreement with 100% of respondents selecting option A, and the referenced Snowflake documentation confirms that encryption keys are rotated when they are more than 30 days old. Options B (60 Days), C (90 Days), and D (365 Days) are incorrect as they exceed Snowflake's standard 30-day rotation period. The comment about deprecated keys being re-encrypted after a year refers to a different process and doesn't contradict the 30-day rotation frequency for active keys.
