C sounds off, findOneQ isn't a standard term in MongoDB.

B is right, find.limit(l) is definitely not the same as findOne().

I thought both findQ and findOneQ return cursors, but I need to double-check if that's correct.

I feel like findOneQ is supposed to return the first document, but I might be mixing it up with find().

I think find.limit(l) is definitely different from findOne(), but I can't recall the exact reason why.

I remember that find() returns multiple documents, but I'm not sure about the specifics of findOne().

Hmm, I'm a bit unsure about this one. I know we need to be really careful about notifying the emergency contact, but I'm not sure which of these scenarios would actually require it. I'll have to think through the potential risks and impacts of each one.

This question is testing my knowledge of single-row functions, which I'm a bit shaky on. I'll need to review my notes and examples to make sure I select the right three statements. Wish me luck!

I'm a bit confused on this one. The question doesn't provide a lot of context, so I'm not sure which factors are most important. I'll have to read through the options carefully.

Hmm, I'm a bit unsure about this one. I know BGP communities are used to control routing behavior, but I'm not sure which one would be the best fit here. I'll have to think it through carefully.

Okay, let me see. Hiring someone else to do the hardware work means we're transferring that risk to another party. I think the answer is C, Transference.
