OMG Exam OMG-OCUP2-FOUND100 Topic 5 Question 23 Discussion

The image depicts a state machine with three states labeled 'state1' and 'state2'. Three events, e1, e2, and e3, are shown triggering transitions.

Analyzing the diagram, we can observe that all three events (e1, e2, and e3) are required for the transition from state1 to state2. The events are arranged sequentially, implying a specific order for the transition to occur.

Here's a breakdown of the reasoning for excluding other options:

Option A (When all of el. e2. and e3 occur in any order) is incorrect because the order of events matters.

Option B (When any one of the events e1. e2. or e3 occurs) is incorrect because all three events are necessary for the transition.

Option D (Never, because a transition cannot have more than one trigger) is incorrect because the state machine can transition with multiple triggers, but in this specific case, the order is crucial.

Therefore, based on the visual representation of the state machine, the correct answer is that the transition to state2 happens only when events e1, e2, and e3 occur in precisely the specified order
