Discuss OMG OMG-OCSMP-MBI300 Exam Topic 3 Question 80

Choose the correct answer.

Given a system for keeping birds away from airports One component, described by the following diagram directs audio signals at birds that approach a runway, its parts, as part properties, are typed by blocks.

A systems engineer has identified some blacks that type the pan properties, but as the design becomes more specific, the engineer discovers that these blocks exist in multiple variants.

What modeling choice does the engineer face at this point?

Awhether to model part properties as (a) a library, or (b) a logical hierarchy

Bwhether to model part properties as (a) a library or (b) a hierarchy of non-composite relationships

Cwhether to model variants of blocks that type part properties as (a) explicit subclasses of the blocks, or (b) part-specific types.

Dwhether to model variants of blocks that type part properties as (a) implicit subclasses of the blocks, or (b) part-specific types

A hierarchy of non-composite relationships sounds better. B could work too!

Dona 1 month ago

I'm leaning towards A. A library could simplify management.

Clement 2 months ago

I agree, C seems right. Explicit subclasses clarify the variants.

Cheryl 2 months ago

This question is tricky! I think C makes the most sense.

Huey 2 months ago

But what about option A? A library could simplify access to properties.

Alesia 2 months ago

I agree, C is good. It helps in managing the variants better.

Marcelle 2 months ago

I feel like option C makes the most sense. Explicit subclasses seem clearer.

Alishia 2 months ago

This question is tricky! I think it's about how to organize the blocks.

Salena 3 months ago

I’m torn between B and D. Hierarchies can be complex but useful for non-composite relationships.

Una 3 months ago

I lean towards A. A library could simplify management of part properties.

Keva 3 months ago

I think option C makes the most sense. Explicit subclasses seem clearer for variants.

Alline 3 months ago

This question is tricky. I feel like it's testing our understanding of modeling choices.

Tabetha 3 months ago

Why not just use a library? Seems simpler to me.

Paul 4 months ago

Totally agree with C, it’s the most flexible approach.

Lasandra 5 months ago

Wait, are we really considering implicit subclasses? That seems risky!

Alease 5 months ago

I think option C makes the most sense here.

Genevieve 5 months ago

Sounds like a classic case of subclassing vs. part-specific types!

Alona 6 months ago

I feel like this is a classic case of part-specific types.

Rebeca 6 months ago

A library vs. hierarchy is a tough call.

Sharen 6 months ago

Surprised there's so much complexity in modeling.

Roy 6 months ago

Nah, I disagree. Part-specific types make more sense!

Margurite 6 months ago

I think it's definitely about explicit subclasses.

Malissa 6 months ago

I feel like the answer might be about part-specific types, but I can't recall the exact implications of using subclasses versus types in this context.

Jerry 7 months ago

I think the key here is understanding the difference between implicit and explicit subclasses, but I’m a bit confused about which one applies to part properties.

Vinnie 7 months ago

This question feels familiar; I think we practiced something similar where we had to choose between libraries and hierarchies.

Amie 7 months ago

I remember discussing how modeling choices can impact system flexibility, but I'm not sure if it's about explicit subclasses or part-specific types.
