Choose the correct answer:

What is true about a MOF 2.x Model?

Show Suggested Answer Hide Answer
Suggested Answer: B

A MOF (Meta Object Facility) 2.x Model is not always a valid UML (Unified Modeling Language) 2.x Model. The MOF 2.x and UML 2.x serve different purposes and have different scopes of application.While UML is a general-purpose modeling language used to define software systems, MOF is a language for defining metamodels, which can include UML itself1.

The MOF 2.x specification provides the basis for metamodel definition in OMG's (Object Management Group's) family of modeling languages, which includes UML.However, it is based on a simplification of UML 2's class modeling capabilities1.MOF is designed to be simpler, directly implementable, and provides a set of CORBA interfaces for manipulating meta objects2.In contrast, UML is used as a general-purpose modeling language with potentially many implementation targets2.

Therefore, a MOF 2.x Model can be a valid UML 2.x Model when certain limitations are observed, such as adhering to the simplified class modeling capabilities that MOF is based on.This means that while a MOF model can resemble a UML model in terms of visual representation, it is fundamentally a MOF model, and its validity as a UML model depends on the extent to which it conforms to the UML specifications

I'll go with B. Gotta love those 'certain limitations' - probably a bunch of caveats that only the exam creators understand.

D is just too vague. There's a clear distinction between a MOF 2.x Model and a UML 2.x Model, even if only theoretical computer scientists care about the details.

A is definitely wrong. A MOF 2.x Model is not always a valid UML 2.x Model. That's like saying a square is always a rectangle.

C seems more accurate to me. The visual representation may resemble UML 2.x, but the underlying model is actually a MOF-based model.
