Nope, it’s just an empty document, nothing fancy!

I think it just gets an auto-generated _id.

I feel like the answer is A, but I also remember something about ObjectId being assigned automatically.

I’m a bit confused; I thought the insert would create a new document with a unique _id, but I can't recall the exact details.

I think an empty document gets inserted, but I'm not entirely sure if it will have an _id or not.

I remember practicing a question where an empty document was inserted, so I’m leaning towards option D.

I'm feeling pretty confident about this one. The scenario clearly outlines the customer data issues, like duplication and lack of synchronization, that an MDM tool is designed to solve. I'll select data duplication, data accuracy/quality, and data completeness.

Okay, let me see. I know tags can make data more understandable, so I'm leaning towards C.
