I agree with B. It covers nested states well.

D seems wrong. Only exit actions? That’s too limiting.
AL

I lean towards A and B. Composite states are tricky.

B makes sense. Entry and exit actions are key.

I feel unsure about this one.

C is a bit confusing, I’m not sure about that one.

D seems wrong, exit actions only? That doesn't sound right.

I think A is misleading, Composite states can use boundary transitions too.

B is definitely true, I've seen it in action.

Hmm, I think A and B are the way to go. Gotta love those state model transitions!

Haha, this question is a real brain-teaser! I'm going with B and D, just to be safe.

C and D are the true statements. Concurrent states can use boundary transitions, but composite states must use them.
LA
Lasandra

I'm pretty sure A and B are the right answers. Composite states can use boundary transitions, but concurrent states must use them.
MI

I’m confused about option D. I thought both entry and exit actions were triggered when crossing state boundaries, but now I'm not so sure.
RU

I feel like I’ve seen a question like this before, and I think it was about concurrent states not necessarily needing boundary transitions. Could that be option C?
AL
Alpha

I'm not entirely sure, but I remember something about composite states needing boundary transitions. Maybe that's option A?
GR

I think option B sounds familiar because we discussed how entry and exit actions work in nested states during our last practice session.

I remember learning about this in class. The tricky part is distinguishing between composite and concurrent states. I'm pretty sure B and C are the correct statements, but I'll double-check my notes just to be sure.

Okay, I think I've got this. Boundary transitions are used for composite and concurrent states, but the key difference is that composite states can use them optionally, while concurrent states must use them. And when a transition crosses state boundaries, the exit actions are always executed. I'm feeling good about B and C as the answers.
CO

B and D seem correct to me. Crossing state boundaries definitely triggers entry and exit actions.
CA
Catalina

I think B and D are correct.
AN

Wait, I thought concurrent states had to use boundary transitions?
SA
Salina

Hmm, I'm a bit confused on this one. I know transitions and state boundaries are important, but I'm not sure about the specifics of when entry/exit actions are executed. I'll have to think this through carefully.

I'm pretty sure the answer is B and C, but I'm not totally confident about it. I'll need to review the concepts of composite and concurrent states again.
KA

Let’s review the definitions of those states to be sure!
BU

I feel like B and D could be a possibility too.
KE

C seems off to me. Composite states have specific rules.
EV
Eve

I agree, but I’m not sure about C.
DA

I think B is definitely correct.
