Not sure about that definition, sounds off to me.

Wait, isn't it just a foreign key?

Totally agree, it's about multiple attributes!

I think it's just a primary key, not both.

A composite key is definitely made up of two or more attributes.

I think option A is incorrect because it limits the composite key to just the first two attributes, which doesn't seem right.

I vaguely recall something about composite keys being related to primary keys, but I can't remember the exact definition.

I remember practicing a question that mentioned composite keys as a combination of attributes, so I feel like D might be the right choice.

I think a composite key involves multiple attributes, but I'm not sure if it's just primary keys or if it can also include foreign keys.

Hmm, I'm a bit unsure about the difference between a composite key and a foreign key. I'll have to think this through carefully.

Easy one! NR definitely supports flexible subcarrier and bandwidth configuration. I've got this.

I've seen this error before. Based on my experience, I think the most likely reason is that the Information Server didn't receive a response from the Normal Server. I'll select option D.

Hmm, I'm a bit unsure about this one. Object-Oriented Analysis and Design, Business Process Management, and Enterprise Application Integration all seem related to service-orientation in some way. I'll have to think this through carefully.
