SOA SOA Certifications S90-03A Questions & Answers

• Question 31:

  Which service-orientation principle influences the content published about services and further helps avoid the misinterpretation of service contracts? Select the correct answer.

  A. Service Statelessness

  B. Service Discoverability

  C. Service Autonomy

  D. None of the above.

  Correct Answer: B

• Question 32:

  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.

  A. Service Composability

  B. Service Discoverability

  C. Service Reusability

  D. There is no service-orientation principle that addresses this issue.

  Correct Answer: A

• Question 33:

  The Service Composability principle is solely dedicated to making services effective composition controllers. Select the correct answer.

  A. True

  B. False

  Correct Answer: B

• Question 34:

  The principle is primarily concerned with ensuring that services exercise a high level of control over their underlying runtime execution environment. Select the correct answer.

  A. Service Performance

  B. Service Autonomy

  C. Service Agility

  D. Service Abstraction

  Correct Answer: B

• Question 35:

  I was discussing my new service with a client who told me that my technical service contract revealed too much information about the underlying service design. For example, based only on the names of my service capabilities, my client could determine that the service was using an Oracle database. What service-orientation principle should I apply to address this problem? Select the correct answer.

  A. Service Reusability

  B. Service Discoverability

  C. Service Autonomy

  D. Service Abstraction

  Correct Answer: D

• Question 36:

  Project Team A delivered 3 services and a month later Project Team B delivered 5 services. After an audit of the services delivered by these two project teams, it was determined that 3 of the services delivered by Project Team B contained redundant logic that already resides in 2 of the services originally delivered by Project Team A. The audit results are negative because it is considered undesirable to have redundant logic among services. Which service-orientation principle could have been applied to help avoid this result? Select the correct answer.

  A. Service Statelessness

  B. Service Reusability

  C. Standardized Service Contract

  D. Service Abstraction

  Correct Answer: B

• Question 37:

  The Service Statelessness principle is focused on the design of the service contract because that's where state data is defined and deferred. Select the correct answer.

  A. True

  B. False

  Correct Answer: B

• Question 38:

  Which are the three design principles that often act as regulators to ensure that the remaining five principles are properly applied: SELECT ALL THAT APPLY

  A. Service Loose Coupling

  B. Service Abstraction

  C. Service Composability

  D. Service Reusability

  Correct Answer: ABC

• Question 39:

  Which of the following statements is true? Select the correct answer.

  A. Service compositions can challenge the traditional notion of interoperability because they rely heavily on integration and therefore make integration an intrinsic process of service delivery.

  B. Service compositions can challenge the traditional notion of integration because services are ideally designed to be intrinsically interoperable and therefore require less integration effort when assembled into service compositions.

  C. Service compositions can challenge the traditional notion of interoperability because they consist of distributed programs (services) and integration is rarely carried out across applications that are remotely distributed.

  D. None of the above statements are true.

  Correct Answer: B

• Question 40:

  When applying the Service Loose Coupling design principle, we want to the coupling between the service contract and service consumers and the coupling of the service contract to its underlying logic. Select the correct answer.

  A. reduce, reduce

  B. reduce, increase

  C. increase, reduce

  D. increase, increase

  Correct Answer: A
