Actual exam question for OMG's OMG-OCUP2-ADV300 exam

Question #: 33
Topic #: 11

Choose the correct answer:

Consider the following diagram:

Which statement is correct about the diagram?

AEach subclass of Electronic Device Kind must have a set of required Certifications defined.

BEach subclass of Electronic Device in the shown Generalization Set must have a set of required Certifications defined.

CThe 'Electronic Device Kind' Class and the 'Electronic Device Kind' Generalization Set have the same name, but no semantic connection is implied by this.

DThese are two alternative but incompatible ways to specify Electronic Device Kinds, either as Class 'Electronic Device Kind' or as Specialization of 'Electronic Device'.

Show Suggested Answer

Suggested Answer: A

The diagram depicts Electronic Device Kind as a class that requires a set of Certifications (required : Certification[1..*]). This implies that any subclass of Electronic Device Kind must provide a set of required Certifications because the multiplicity [1..*] indicates that at least one Certification is mandatory for each instance of Electronic Device Kind or its subclasses. Therefore, when a subclass is created, it inherits the requirement to specify what Certifications are needed. This is a standard UML generalization, where the subclass inherits the attributes and constraints of its superclass. This interpretation is consistent with the rules defined in the UML 2.x Superstructure Specification, which includes the semantics of class generalization and attribute inheritance.

I see your point, but I still think A is the best choice because it makes more sense in this context.

Option A is clearly wrong. Why would each subclass need its own set of certifications? That doesn't make any sense. I'm going with B.

I agree, option A doesn't seem logical. B seems like the correct choice.

Haha, looks like someone got a little too creative with the naming conventions. I'm going with Option D - these are just two different ways to represent the same thing.

Yeah, it does seem like they are just different ways of representing the same thing.

I'm not sure, but I think Option C might be the right answer. The class and the generalization set have the same name, but they don't seem to be semantically connected.

I agree with Option C. The names being the same doesn't necessarily mean they are connected.

Option B seems correct to me. The diagram clearly shows a generalization set for Electronic Device, so each subclass must have the required certifications defined.
