[All OMG-OCUP2-ADV300 Questions]

Choose the correct answer:

Which statement is correct about redefinition of simple States?

AA simple State cannot be redefined

BA simple State can be redefined by excluding it in a redefined StateMachine.

CA simple State can be redefined as a composite State with one or more Regions.

DState Redefinition is not a UML capability.

Show Suggested 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.

Excluding it in a redefined StateMachine sounds right to me!

Wait, is State Redefinition really not a UML capability?

I vaguely recall that UML does allow for some form of State Redefinition, so I don't think D is correct.

I feel like I've seen a question similar to this before, and I think the answer was about how simple States can be redefined in certain contexts.

I think I remember that a simple State can actually be redefined, but I'm not sure if it can be done as a composite State.

I'm pretty confident that the answer is A - a simple State cannot be redefined. That's a key principle of UML that I'm sure about.

I remember learning about State Redefinition in class, so I think the correct answer is C. A simple State can be redefined as a composite State.

Option B seems plausible - a simple State can be redefined by excluding it in a redefined StateMachine. But I'm not 100% certain.

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.

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.
