OMG-OCUP2-FOUND100 Exam - Topic 3 Question 25 Discussion

Actual exam question for OMG's OMG-OCUP2-FOUND100 exam
Question #: 25
Topic #: 3
[All OMG-OCUP2-FOUND100 Questions]

Choose the correct answer:

Consider the following diagram:

Which statement is correct according to the diagram?

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 feel like option B is definitely wrong. I recall that Clients and Managers often share some common attributes in similar diagrams.

I'm a bit confused about option C. Can responsiblePerson really not refer to a Client? That seems a bit restrictive.

I remember a practice question where we discussed relationships between classes. I feel like option D could be right because a Manager might fit the role of responsiblePerson.

I think option A might be correct since it mentions inheritance, which we covered in class. But I'm not entirely sure.

I'm feeling a bit uncertain about this question. The diagram is complex, and I want to make sure I'm not missing any important details. I'll review the options carefully and try to eliminate the incorrect ones.

Okay, I think I've got it. The key is to focus on the "responsiblePerson" class and its relationship to the other classes. Let me re-read the options and select the best one.

Option D is correct. The object referred to as responsiblePerson can be a Manager, as the diagram shows that Manager inherits from Person, and responsiblePerson is a subclass of Person.
