OMG Exam OMG-OCUP2-ADV300 Topic 8 Question 24 Discussion

State Machine Events in UML are triggers for transitions and do not classify as objects or classifiers; thus they do not inherently have features:

A . Incorrect, because State Machine Events are not treated as classifiers with features.

B . Incorrect, though it hints at an extended use case, State Machine Events do not extend classifiers in standard UML usage.

C . Correct, State Machine Events are not Classifiers and therefore cannot have features such as properties or operations.

D . Incorrect, because UML State Machines certainly have an Event concept, but these Events are not classified as having features.

UML Specification: State Machine chapter, specifically sections discussing the nature of events and triggers.

Further insights can be found in the event and trigger management sections of the UML 2.5 Documentation.
