Exam 3: SOA Design & Architecture (S90-03A)

The following statement describes the relationship between the Service Reusability principle and which other design principle? "Because of the potentially high performance and concurrent usage demands of reusable services, the extent of control they can exercise over their underlying environment is an important design consideration in guaranteeing an acceptable level of predictable runtime behavior." Select the correct answer.

The __________________ principle can be applied together with the __________________ principle and the __________________ principle to establish a service contract that conforms to design standards, does not impose negative dependencies upon service consumers, and does not reveal unnecessary information about its underlying implementation. Select the correct answer.

Which of the following is a common challenge imposed by the adoption of service-orientation? Select the correct answer.

The service-orientation principle primarily concerned with ensuring the runtime behavioral predictability of a service is: Select the correct answer.

Besides the Standardized Service Contract principle, which of the following service-orientation principles are also primarily focused on the design of the service contract? SELECT ALL THAT APPLY

Which of the following is not a benefit associated with silo-based application design? Select the correct answer.

Often it is a requirement to wrap a legacy system with a service. This is typically accomplished by encapsulating calls to the legacy system's Application Programming Interface (API) within the core logic of the service. Care must be taken to not expose details of the underlying API through the service contract as it may unintentionally couple the service consumer to the legacy system. Which pair of service-orientation principles directly addresses this concern? Select the correct answer.

A service is sometimes referred to as an enterprise resource because: Select the correct answer.

Which of the following are not service-orientation design principles? Select the correct answer.

The Service Discoverability principle is primarily concerned with increasing the __________________ of the information published about a service. Select the correct answer.

The definition of the Service Composability design principle is as follows: "Services are effective composition participants, regardless of the size and complexity of the composition." What is meant by "regardless of the size and complexity of the composition"? Select the correct answer.

Which of the following is not a negative coupling type? Select the correct answer.

Which of the following is not a design characteristic that is realized by the application of the Service Reusability principle? Select the correct answer.

A service contract publishes information that makes guarantees about how the service will behave at runtime and when it will be available. These types of guarantees are associated with which service meta information type? Select the correct answer.

The enforcement of service contract design standards is required to effectively apply the Standardized Service Contract principle. Select the correct answer.

Service compositions can only be assembled from services that belong to the same service inventory. Select the correct answer.

The __________________ principle encourages services within the boundary of a specific service inventory to share messages based on the same data models. This practice directly supports the __________________ principle, which is concerned with designing services so that they can be effectively and repeatedly aggregated into different solutions. Select the correct answer.

Which of the following are runtime roles associated with service compositions? SELECT ALL THAT APPLY

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

Service-orientation establishes a distinct approach to carrying out a(n) __________________. Select the correct answer.
