Choose the correct answer:

The BchaviorA state machine shown below is at rest in state s1 and the value of x Is 0.

If a signalA event occurs, what is the state machine's subsequent behavior?

Show Suggested Answer Hide Answer
Suggested Answer: C

The image showcases a state machine named 'BehaviorA'. It consists of two states: s1 and s2. There's also a transition labeled 'signalA' connecting these states. However, a guard condition, '[x > 0]' is placed on the transition. This indicates that the signalA event will only trigger the transition if the expression x > 0 evaluates to true.

In the scenario you described, the state machine is currently in state s1, and the value of x is 0. Since the guard condition '[x > 0]' is not satisfied (because x is 0), the signalA event will not trigger a transition to state s2.

Here's a breakdown of why other options are incorrect:

Option A (The state machine will transition to state s2 and execute ActivityA during the transition) is not valid because the guard condition prevents the transition.

Option B (The state machine will execute ActivityA and remain in state s1) is incorrect as ActivityA is only associated with the transition, which isn't happening in this case.

Option D (The state machine will remain in state s1, and processing of the signalA event occurrence will be deferred until either the value of x changes or the state machine changes state) is not entirely accurate. While the state machine remains in s1, the processing of the signalA event is consumed immediately, not deferred.

Therefore, considering the state machine's visual representation and the guard condition, option C best describes the state machine's behavior. The signalA event is acknowledged but has no effect because the transition requirements aren't met.

I agree with Melita, option A seems to be the most logical choice.

I don't know, man. This whole state machine thing is giving me a headache. Maybe I should just go with option C and call it a day. At least the state machine will stay put, right?

Whoa, this is tricky. I'm going to have to go with option A. The state machine transitions to s2 and executes ActivityA. Gotta keep those state machines moving, you know?

Hmm, I'm not sure. Let me think this through... Ah, I got it! It's option D. The state machine stays in s1 and defers the signalA event until something changes. Simple enough.

C'mon, it's clearly option B. Who wouldn't know that the state machine will just execute ActivityA and stay in state s1? Amateur hour over here.

No way, it's definitely option B. The state machine will execute ActivityA and remain in state s1.
