C for sure! Otherwise, it could mess up the whole database.

C is the correct answer! Parent can't be deleted if there are child references.

I feel like I might be confusing this with ON DELETE CASCADE. I just can't recall if NO ACTION means it does nothing or if it prevents deletion like option C suggests.

I practiced a question similar to this, and I remember that ON DELETE NO ACTION prevents deletion of the parent if there are existing child references. So, I think option C is correct.

I'm not entirely sure, but I remember something about referential integrity constraints. I think it might be related to option C, but I could be mixing it up with another type of constraint.

I think ON DELETE NO ACTION means that if you try to delete a parent key, it won't let you if there are child keys referencing it.

Okay, let me break this down. Ensuring data is only accessed by authorized people - that sounds like confidentiality to me. I'm going with D.

I'm a bit unsure about this one. The image is complex, and the options all sound plausible. I'll need to rely on my network security knowledge to make an informed decision.

I'm a bit confused on this one. I'm not sure if any of these options would actually improve the stability and reliability. I'll need to review the course material again before answering.

Definitely B. NO ACTION means the database doesn't do anything special when deleting the parent key. It's up to the application to handle the referential integrity.

Haha, I almost picked D just for the fun of it. Automatically setting all child keys to a specified value? That's a bit extreme for a 'NO ACTION' constraint!

But if the parent key is deleted, wouldn't it make sense for the child keys to be set to a specified value?

I was going to choose C, but then I realized that would be the ON DELETE RESTRICT constraint, not NO ACTION. B makes the most sense here.

I think the correct answer is B. The question clearly states 'NO ACTION', which means no test is made for referential integrity when deleting the parent key.
