Discuss OMG OMG-OCUP2-ADV300 Exam Topic 2 Question 35

Choose the correct answer:

A developer wants to make sure that each specialization of Class Bicycle has its own unique set of values for the suitable road surface and average speed

Which diagram imposes these requirements?

AOption A

BOption B

COption C

DOption D

Suggested Answer: C

In Option C, the properties suitable road surface and average speed have been redefined in the subclasses Recumbent Bike and Racing Bike. The use of the {redefines} keyword in UML signifies that the subclass will provide its own specific values for these properties, overriding the general ones provided by the superclass Bicycle. This is the correct way to enforce that each specialization of Bicycle has a unique set of values for these attributes, as redefinition allows for the customization of inherited properties on a per-subclass basis. The use of {redefines} is specified in the UML 2.x Superstructure Specification, which describes how properties inherited from a superclass can be customized by subclasses.

I agree with Lucia, C makes the most sense here.

Elliott 10 months ago

I think it's actually Option B.

Lucia 10 months ago

Option C looks like the right choice for unique values.

Jarod 10 months ago

Definitely A! Each subclass should have its own properties.

Maia 10 months ago

Wait, are we sure about that? I thought they could share values.

Renato 11 months ago

I think option B could be it, but I’m a bit confused about how to differentiate between the options. I need to double-check my notes on this.

Laurel 11 months ago

I recall something about UML diagrams and how they represent class relationships. I hope I remember the specifics correctly for this one.

Ligia 11 months ago

I'm not entirely sure, but I feel like option C might be the right choice since it shows unique attributes for each subclass.

Soledad 11 months ago

I think this question is about inheritance and how subclasses can have their own properties. I remember practicing a similar question.

Nettie 12 months ago

I'm a little confused by the wording of the question. Does it mean that each specialization needs to have its own set of attributes, or just that the values for those attributes need to be unique? I'll need to re-read it carefully.

Isabelle 12 months ago

I'm feeling pretty confident about this one. Option D seems to be the clear choice since it allows for the unique values per specialization, which is exactly what the question is asking for.

Edward 12 months ago

Okay, I think I've got this. The key is that each specialization needs its own unique set of values, so I'm going to go with Option D since it has separate attributes for each subclass.

Hmm, I'm a bit unsure about this. The question is asking for a specific diagram, but I'm not sure which one captures the unique values for each specialization.

Juan 1 year ago

This looks like a tricky one. I'll need to carefully analyze each diagram to see which one best meets the requirements.

Nina 1 year ago

Option C all the way, baby! It's like a bicycle built for one... with its own special features. Gotta love that specialization!

Alease 1 year ago

Option A? Really? That's like putting a square peg in a round hole. If the question is about ensuring unique values, that diagram definitely doesn't cut it.

Blondell 1 year ago

I agree with Paz, Option B seems to be the best choice

Paz 1 year ago

I'm leaning towards Option B because it shows specialization

Rolland 1 year ago

Hmm, this is a tough one. I'm leaning towards Option B, but I could see the argument for Option C as well. Gotta love these tricky UML diagram questions!

Kandis 1 year ago

I disagree, I believe it's Option C

Ettie 1 year ago

I'm voting for Option D. The inheritance hierarchy ensures that each subclass can have its own unique values for the road surface and average speed.

Shawn 1 year ago

Option C looks like the way to go. Each specialization of Bicycle has its own attributes, which seems to fit the requirements.

Yes, Option C clearly shows the separation of attributes for each specialization of Bicycle. It's the most suitable diagram.

I agree, Option C seems to be the best choice for ensuring each specialization of Bicycle has unique values.

Cathrine 1 year ago

I think the correct answer is Option A
