Actual exam question for Arcitura Education's S90.03 exam

Question #: 85
Topic #: 4

Which of the following statements correctly explains the difference between the Service Abstraction and Service Loose Coupling principles? Select the correct answer.

AService Abstraction is focused on dependencies that exist between the service contract and its underlying logic, whereas Service Loose Coupling is focused on fostering 'loose state' in support of runtime state deferral

BService Abstraction is focused on agnostic service logic only in order to establish an agnostic abstraction layer, whereas Service Loose Coupling is focused on the relationship between the service contract and service consumers.

CService Abstraction is focused on hiding information about service implementation details, whereas Service Loose Coupling is focused on the positioning of the service contract in relation to the service implementation and service consumers.

DThere is no difference between these two principles. One principle name is used instead of the other depending on whether you are building loose or tight service abstraction layers.

A seems a bit off to me. What’s 'loose state' even mean?

I feel like option D is too simplistic. I recall that there are distinct purposes for both principles, but I can't quite remember the specifics.

I practiced a similar question last week, and I chose an answer that emphasized the relationship between contracts and consumers. I might go with B, but I’m not completely confident.

I think Service Abstraction is about hiding implementation details, while Loose Coupling deals with how services interact. That makes me lean towards option C.

I remember studying the definitions, but I'm not entirely sure how to differentiate between abstraction and loose coupling. They seem related.

Option C looks like the best explanation to me. Service Abstraction is about encapsulation, while Service Loose Coupling is about the contract-consumer relationship. I feel confident that's the right way to differentiate them.

I'm a bit confused on the difference between these two principles. The wording in the answer choices is quite technical, so I'll need to re-read them carefully to determine the right answer.

The key seems to be that Service Abstraction is about hiding implementation details, while Service Loose Coupling is about the relationship between the contract and consumers. I think option C best captures that distinction.

Ah, finally a question that really gets to the heart of the matter. Option C seems to be the clear winner here - the distinction between hiding implementation details and the positioning of the service contract is key.
