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

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.

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.
