Totally agree, just 1NF is enough here!

Wait, are we sure about that? Seems too simple for 3NF.

No way, it can't be in 3NF with just that info!

I think it's also in 2NF because of the dependencies.

It's definitely in 1NF since there's a unique identifier.

I’m leaning towards option B, 1NF and 2NF, but I’m not completely confident about the definitions of each normal form.

I feel like it could be in 3NF since there are no transitive dependencies, but I need to double-check what that means exactly.

I remember practicing a similar question where we had to determine normal forms, and I think if there's only one fee per building, it might be in 2NF too.

I think this table is in 1NF because it has a primary key and no repeating groups, but I'm not sure if it meets the criteria for 2NF.

This seems like a 2NF question to me. The key (Student_ID) fully determines the other attributes, and there are no partial dependencies. I'll double-check, but I think the answer is B.

I'm not totally confident on this one. I'll need to review the definitions of the normal forms to make sure I pick the right answer. Better to take my time and think it through carefully.

Okay, let's see. If each building charges only one fee and a student can live in only one building, then the table is in 3NF, right? The key (Student_ID) fully determines the other attributes.

Hmm, I'm a bit unsure about this one. The table seems simple, but I want to make sure I understand the requirements for each normal form correctly before answering.

This looks like a straightforward database normalization question. I'll review the key details and think through the normal forms step-by-step.

Whoa, this is a tough one. I better review my notes and examples from class to see if I can find anything similar. Hopefully I can adapt those techniques.

Hmm, I'm a bit unsure about this one. I know the subnet mask has to match the IP address, but I'm not totally confident in my subnet mask knowledge. I'll have to think this through carefully.

This question seems straightforward, I think I'll go with option B to remove the user from the business unit.

If I recall correctly, a cash basis taxpayer recognizes gains when they actually receive cash, so maybe it's the date of receipt of cash proceeds?

Wait, what's a BCNF? I think I need to brush up on my database normalization before the exam.

Exactly, each normal form builds on the previous one to reduce redundancy and improve data integrity.

So, if the table is in BCNF, it means it's also in 1NF, 2NF, and 3NF.

BCNF stands for Boyce-Codd Normal Form. It's a higher level of normalization in databases.

I've seen this type of question before. The table is in 1NF, 2NF, and 3NF, so C is the right answer. Easy peasy lemon squeezy!

This is a classic database normalization question. The table is in 1NF, 2NF, and 3NF since there are no partial dependencies or transitive dependencies.
