Question 3
The Universal SOA Commission (USOAC) has been standardizing the service-oriented architectural model since 1998. Their role is to regulate the marketplace to ensure that all usages of the "SOA" acronym for branding purposes are legitimate. They enforce this via product assessment and certification, a process that all of the major software vendors follow to obtain official USOAC certification.

Question 12
Which of the following statements makes sense?
A. I am going to register my new service in the service registry so that other project teams can discover it in order to determine whether they should reuse it as part of service-oriented solutions they are planning to build.
B. I am going to register my new service inventory in the service registry in order to improve the performance of my service-oriented solution, because other services in my service composition will be able to dynamically discover and retrieve the new service much faster than if it was not registered in the service registry.
C. I am going to register my new service in the service registry because Service Registration is one of the eight principles of service-orientation.
D. None of these statements make sense.

Question 13
I built a service-oriented solution a year ago comprised of 3 services. I've just been told that the business process automated by the solution is going to be replaced by a new business process that introduces some changes to how the business process logic needs to be automated. What should I do?
A. Replace the solution with a brand new service-oriented solution comprised of new services designed specifically to automate the new business process.
B. Identify the services within the solution that are no longer relevant to the new business process and permanently retire them so that no other service-oriented solution inadvertently uses them.
C. Assuming there is an established service inventory in place, attempt to locate any existing services that can provide the logic required to automate the new business process and then change how the services within the solution need to be composed, as required.
D. Due to the fact that service-oriented solutions are inherently unable to adapt to business process change, you should investigate for how long you can continue to use your current solution. Even if it does not exactly provide the functionality required by the new business process, it is still likely to automate a subset of the new business process logic, thereby providing you with an opportunity to continue to get some value from the solution before you are forced to retire it.

Question 14
Service Composition A is comprised of 4 services. Service Composition B is comprised of 6 services. Because both service compositions are comprised of services from the same service inventory, the service inventory will have a total of how many services?
A. 10
B. 24
C. Based on the information provided, it's impossible to know how many services reside in the service inventory because we don't know how many other service compositions exist.
D. Based on the information provided, it's impossible to know how many services reside in the service inventory because the quantity of services within a service inventory is not determined by the quantity of services in service compositions.

Question 15
Which of the following is an expected result of successfully adopting SOA?
A. A natural increase in runtime performance that you will gain as a result of the fact that service compositions will often be comprised of a greater amount of individually participating programs (services) than traditional distributed applications.
B. The fact that the existing IT organizational structure will not have to change because of how well a service-oriented enterprise fits into traditional IT departmental structures that are focused on project-centric application delivery.
C. The tactical (short-term) focus of service-orientation, which allows for the initial rapid delivery of services without concerns about their subsequent governance.
D. The strategic (long-term) target state that is attainable when many of the services delivered are interoperable and reusable, thereby allowing for them to be repeatedly composed in response to new and changing business requirements.
