the correct answer.

A. Applications are always inherently built for repeated reuse across silos. B. The latest technology advancements can be leveraged by repeatedly building new

Correct Answer: A

QUESTION NO: 7
The __________________ principle encourages services within the boundary of a specific
service inventory to share messages based on the same data models. This practice directly
supports the __________________ principle, which is concerned with designing services
so that they can be effectively and repeatedly aggregated into different solutions. Select the
correct answer.

QUESTION NO: 10
Which of the following statements correctly explains the difference between the Service
Reusability and Service Composability principles? Select the correct answer.

Composability is focused on creating highly isolated services. B. There is no difference between these two principles. One principle name is used instead
of the other depending on whether you are building a task or entity service. C. Service Reusability is focused on creating generic, reusable service logic, whereas
Service Composability is focused on creating services that are effective participants of
multiple service compositions. D. Service Reusability is focused on creating non-agnostic service logic, whereas Service
Composability is focused on creating agnostic service logic.

Correct Answer: C
