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

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?
A) whether to model part properties as (a) a library, or (b) a logical hierarchy
B) whether to model part properties as (a) a library or (b) a hierarchy of non-composite relationships
C) whether to model variants of blocks that type part properties as (a) explicit subclasses of the blocks, or (b) part-specific types.
D) whether to model variants of blocks that type part properties as (a) implicit subclasses of the blocks, or (b) part-specific types

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

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

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

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

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

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.

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.

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

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.
