Question 1

The Service Loose Coupling principle advocates which of the following coupling types? Select the correct answer.

AContract-to-Implementation

BConsumer-to-Contract

CLogic-to-Contract

DNone of the above.

Answer : C

Question 2

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

AService-orientation introduces the need for design standards, which need to be followed and enforced.

BService-orientation requires that you commit to one vendor platform, which can limit your product options.

CService-orientation requires that services be protected from repeated reuse, which can reduce potential ROI.

DService-orientation introduces the need to make all implementation details about each service publicly available, which can lead to the misuse of this information by some project teams.

Answer : A

Question 3

By providing __________________ awareness of reusable services available for composition, the __________________ principle can greatly benefit the design of service-oriented solutions. Select the correct answer.

Aincreased, Service Statelessness

Bdecreased, Service Autonomy

Cdecreased, Service Discoverability

DNone of the above.

Answer : D

Question 4

Common problems associated with silo-based application design include: SELECT ALL THAT APPLY

AIt can result in a significant amount of waste due to the fact that silo-based applications can have significant redundant functionality.

BIt can result in bloated, oversized technical environments.

CThe integration effort required to make disparate silo-based applications interoperate can be complex and expensive.

DIT operational costs can continue to escalate as more silo-based applications are added to an IT enterprise.

Answer : A, B, C, D

Question 5

Fill the blank for the following definition of the Service Statelessness design principle: "Services minimize resource consumption by __________________ the management of state information when necessary." Select the correct answer.

Aincreasing

Bencapsulating

Cdeferring

Dassuming

Answer : C

Question 6

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.

AIt means that services need to be designed so that they can participate in different types of compositions, regardless of what type of composition they are initially delivered for.

BIt means that services need to be designed for a specific composition with a specific size and level of complexity, regardless of what other compositions may need to use the service for in the future.

CIt means that the composition must be large and complex, regardless of the size and complexity of the service itself. These two design aspects need to be kept separate so that service and composition can evolve independently.

DThe definition for the Service Composability principle does not include the statement 'regardless of the size and complexity of the composition'.

Answer : A

Question 7

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?

AService Autonomy

BService Statelessness

CService Discoverability

DService Abstraction
