[All OMG-OCUP2-ADV300 Questions]

Choose the correct answer:

Which statement is correct about redefinition of simple States?

Show Suggested Answer Hide Answer
Suggested Answer: B

In UML, a simple State can indeed be redefined, but the specifics of how it is redefined matter:

A is incorrect as redefinition of States, including simple States, is permitted.

B is correct. A simple State can be effectively removed or altered through redefinition in a derived StateMachine, which could include changing its type or characteristics.

C suggests that a simple State can be turned into a composite State. While theoretically possible in the context of redefinition, this option might be considered a significant alteration that could be misleading without additional context.

D is incorrect; UML does support State Redefinition.


UML Specification, particularly the sections on Redefinition and StateMachines.

Detailed rules on state redefinition are outlined in the UML 2.5 Documentation, specifically under StateMachine specializations.

C) A simple State can be redefined as a composite State with one or more Regions. That's the one that makes the most sense to me. I mean, what's the point of redefinition if you can't actually redefine the State?

A) A simple State cannot be redefined. Really? That can't be right. The whole point of redefinition is to allow you to add more detail to a State, isn't it? This answer just doesn't seem plausible.

D) State Redefinition is not a UML capability. Hmm, I'm not sure about that. I thought the UML spec allowed for State redefinition, but maybe I'm mistaken.

B) A simple State can be redefined by excluding it in a redefined StateMachine. That's an interesting option, but I don't think it's correct. Redefinition typically involves adding more detail, not just removing a State.

C) A simple State can be redefined as a composite State with one or more Regions. That's the correct answer, as the UML specification allows for the redefinition of a simple State to a composite State.
