During the service modeling process, after all business process steps that belong to agnostic service contexts have been accounted for, the steps that remain should represent logic that is unique to the business process and therefore considered potentially suitable for encapsulation by task service candidates.

  1. True
  2. False

Answer(s): A



When applying service-orientation principles during the service modeling process, the Standardized Service Contract principle is regarded as being of high importance because its application defines how service candidates can be assembled into service composition candidates.

  1. True
  2. False

Answer(s): B



Which of the following is not a valid reason for defining service composition candidates during the service modeling process?

  1. The identification of service composition candidates can help determine the potential size and complexity of service compositions that may need to be created.
  2. The identification of service composition candidates can help identify missing workflow logic or processing steps.
  3. The identification of service composition candidates can help demonstrate the order in which services will eventually need to invoke each other.
  4. The identification of service composition candidates leads directly to the definition of the service contract for the service inventory candidate.

Answer(s): D



During a service modeling process it is noticed that several service candidates contain similar service capabilities that are responsible for logging status information. The service analysts worry that the services will eventually end up containing redundant logic.
Which of the following approaches is suitable for addressing this problem?

  1. The logging service capabilities are moved from the service candidates into a non-agnostic task service candidate that is responsible for the bulk of the service composition logic.
  2. The logging service capabilities are moved from the service candidates into a new set of service candidates residing in a different service inventory.
  3. The logging service capabilities are moved from the service candidates into a logging utility service candidate.
  4. Logging functionality will always need to reside in different services, and there is nothing that can be done to resolve the redundancy of these service capabilities.

Answer(s): C



During the service modeling process it is noticed that a service capability candidate is assigned the responsibility of issuing notification messages via e-mail and logging event status information to a database. Each of the following statements describes the result of applying of a service-orientation principle. Given that the principles are applied during the service modeling process, which of these statements make sense?

  1. The Service Reusability principle is applied and the service capability candidate is split into two service capability candidates. This increases the reusability of the service capability candidate because each provides a distinct and generic function that can be individually reused.
  2. The Service Autonomy principle is applied to help determine whether the shared e-mail server and database may raise autonomy-related problems that may impact how the service capability candidate should be modeled.
  3. The Service Discoverability principle is applied to more clearly define the purpose of the service capability candidate so that information is collected for future discoverability purposes.
  4. The Service Statelessness principle is applied so that the service capability candidate is designed and developed to defer its state data to e-mail messages and a corresponding database table as part of the overall physical service architecture.

Answer(s): A,B,C
