SOA Certified Professional Fundamental SOA & Service-Oriented Computing Sample Questions:
Question 1
Which of the following statements is true?
A. "Contract first" design is an unproven design technique that is not commonly employed when delivering service-oriented solutions and is therefore not considered important to SOA.
B. "Contract first" design is important to SOA because it makes you think about service contract design options at the same time that you are building the underlying service logic.
C. "Contract first" design is important to SOA because it forces you to establish standardized service contracts prior to the development of the underlying service logic.
D. "Contract first" design is important to SOA because without a contract, services cannot be invoked. However, there is no preference as to when, during the service delivery lifecycle, the contract should be designed or established.
Question 2
Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project?
A. Services A and B need to reside on the same physical server or workstation, thereby allowing them to be reused without the need for major integration effort.
B. Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario.
C. Service A needs to be designed using a different vendor platform than ServiceB. This enables vendor diversity, thereby guaranteeing interoperability.
D. Services A and B need to be standardized and designed with an emphasis on intrinsic interoperability so that they are compatible regardless of when or by which project team they are delivered.
Question 3
Which of the following statements makes sense?
A. I am going to register my new service in the service registry because Service Registration is one of the eight principles of service-orientation.
B. None of these statements make sense.
C. 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.
D. 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.
Question 4
I anticipate building larger service compositions comprised of more services. How will this likely affect performance and infrastructure?
A. It will likely reduce performance demands and require an increase in infrastructure investment.
B. It will likely increase performance demands and require an increase in infrastructure investment.
C. It will likely increase performance demands and require a reduction in infrastructure investment.
D. It will not affect performance or infrastructure.
Question 5
Service-oriented analysis and service-oriented design are typical phases of an SOA delivery lifecycle.
A. False
B. True
