Question 2
Which of the following statements are true?
SELECT ALL THAT APPLY
- The adoption of service-orientation can result in an increased overall time and cost for the initial delivery of service logic.
- The adoption of service-orientation can result in increased design complexity due to a constant emphasis on reuse.
- The adoption of service-orientation can result in an emphasis on tactical (short-term) rather than strategic (long-term) planning in order to justify a quick ROI.
- The adoption of service-orientation can result in a need to introduce a governance structure that may introduce new organizational roles and processes.
Correct answer: ABD
Question 3
Which of the following is not a state deferral option that is commonly used in support of applying the Service Statelessness principle?
Select the correct answer.
- database
- utility service
- messages
- service registry
Correct answer: D
Question 4
The design principle most associated with an approach whereby the technical interface or contract of a service is designed prior to its underlying logic is:
Select the correct answer.
- Service Autonomy
- Service Reusability
- Service Composability
- Standardized Service Contract
Correct answer: D
Question 5
A company is about to release a service for worldwide usage. As a result, the service contract receives a great deal of attention. After a review it is decided to limit the service contract content to only what is deemed absolutely necessary and to further have the service's Service Level Agreement (SLA) translated into several different languages so that the service can be easily located by those who may want to use it. Which pair of service-orientation principles directly supports these design-time considerations?
Select the correct answer.
- Service Autonomy, Service Reusability
- Service Statelessness, Standardized Service Contract
- Service Discoverability, Service Abstraction
- Service Reusability, Service Statelessness
Correct answer: C
Question 6
Each time our corporate development team makes a change to the service logic it is required to publish a new version of the service contract. Our customers are complaining because their service consumer programs become incompatible with new service contract versions and therefore no longer work. Which of the following service-orientation principles is most likely to help us solve this on-going problem?
Select the correct answer.
- Service Reusability
- Service Statelessness
- Service Loose Coupling
- Service Autonomy
Correct answer: C
Question 7
When applying the Service Loose Coupling design principle, we want to __________________ the coupling of the service logic to the service contract because that allows the service contract to remain __________________ from the service logic.
Select the correct answer.
- increase, decoupled
- reduce, decoupled
- increase, coupled
- reduce, coupled
Correct answer: A
Question 8
Which of the following service-orientation principles support the application of the Service Composability principle?
SELECT ALL THAT APPLY
- Standardized Service Contract
- Service Autonomy
- Service Integration
- Service Statelessness
Correct answer: ABD
Question 9
The composition member is the runtime role assumed by a service with a capability that is executing the parent composition logic required to compose capabilities within other services. Select the correct answer.
- True
- False
Correct answer: B
Question 10
As a first step toward replacing a corporate customer database, a company attempts to limit access to customer services via an official Customer entity service. However, some time later it is discovered that several applications have been bypassing the Customer service in order to directly access the customer database. As a result, these applications exhibit which negative form of coupling?
Select the correct answer.
- Contract-to-Implementation
- Consumer-to-Implementation
- Consumer-to-Contract
- Contract-to-Technology
Correct answer: B
