Aha! I've got this one. The answer is clearly C) 14 days. Why? Because 12 hours is just too short, and 31 days is way too long. 14 days is the Goldilocks of result cache durations - not too hot, not too cold, just right!

A) 12 hours is the obvious answer here. If the question specifically mentions 12 hours, then that's gotta be the correct one. Although, I do wonder... does Snowflake have a 'snooze' feature for the result cache? Like, 'Hey, I'm feeling a little lazy today, so let's just keep these results for another 12 hours, mkay?'

Hmm, I'm not too sure about this one. B) 24 hours sounds like a reasonable guess, but I could be totally off. Maybe I should have paid more attention in my Snowflake training sessions.

I'm going with D) 31 days. Surely Snowflake's result cache can hold onto those query results for much longer than just 12 hours, right? I mean, how often does the underlying data really change, anyway?

I think the answer is A) 12 hours. The question states that the dashboard issues the same SQL select clause every 12 hours, so Snowflake should use the persisted query results from the result cache for up to 12 hours.
