Wait, how can totalKeysExamined be 30000 with 0 docs?

Definitely B, using an index here!

I feel like option C makes sense since if no documents were examined, then it likely returned zero results.

I'm not entirely sure, but I think if totalDocsExamined is 0, it means the query didn't return any documents at all.

I remember something about totalKeysExamined being high while totalDocsExamined is zero indicating an index was used.

I practiced a similar question where a high number of keys examined meant the query was efficient, but I can't recall the exact details.

Ah, I know this one! The property setting to automatically increase the deployment version is "Increment Deployment Version". I'm confident that's the right answer.

Hmm, I'm a little unsure on this one. I know there are different types of financial analysis, but I can't quite remember the specific term for comparing year-over-year changes. I'll have to think this through carefully.

Hmm, I'm a bit unsure about this one. I know measures of central tendency have to do with describing the typical or average value in a data set, but I'm not totally clear on the differences between the options. I'll have to think this through carefully.
