Question #11 (Topic: )
I built Service Composition A, which is comprised of 4 services. It was very successful in
that it fulfilled all of its expected business requirements. I was then assigned a new project
that required me to deliver a new service composition called Service Composition B. After
studying the new business requirements, I realized that one of the services in Service
Composition A could be reused "as is" in Service Composition B. However, when I tried to
make it part of Service Composition B, I ran into a number of problems. In the end, it turned
out that even though the service was reusable, it was simply not designed to participate in
more than one service composition. Which service-orientation principle would have
addressed this issue if I would have applied it to the service prior to completing Service
Composition A? Select the correct answer.

Question #12 (Topic: )
A company is about to release a service for worldwide usage. As a result, the service
contract receives a great deal of attention. After a review it is decided to limit the service
contract content to only what is deemed absolutely necessary and to further have the
service's Service Level Agreement (SLA) translated into several different languages so that
the service can be easily located by those who may want to use it. Which pair of service-
orientation principles directly supports these design-time considerations? Select the correct
answer.
