Accepted Answer

A) True 
 B)False

Question 9

Project Team Alpha delivers Service A for Solution 1. Project Team Beta delivers Service B for Solution 2. Some time later, Project Team Omega wants to reuse Service A and Service B for its new Solution 3. How would Services A and B need to have been designed in order for Project Team Omega to successfully reuse these services without having to resort to a major integration project?

Accepted Answer

A)  Services always require the use of transformation technologies in order to communicate. Therefore, major integration effort is unavoidable in this scenario. 
B)  Services A and B need to reside on the same physical server or workstation, thereby allowing them to be reused without the need for major integration effort. 
C)  Services A and B need to be standardized and designed with an emphasis on intrinsic interoperability so that they are compatible regardless of when or by which project team they are delivered. 
D)  Service A needs to be designed using a different vendor platform than Service B. This enables vendor diversity, thereby guaranteeing interoperability.

Question 12

A service inventory is considered to have normalized services when:

Accepted Answer

A)  its scope does not overlap with any existing databases 
B)  service boundaries within the service inventory do not overlap with each other 
C)  each service within the service inventory is not used by more than one service composition 
D)  legacy systems within the service inventory boundary do not overlap with each other

Which of the following statements is true?

Accepted Answer

A)  Service-orientation is a revolutionary design paradigm comprised solely of new design techniques and practices never before used in IT's history. 
B)  The only known historical influence of the service-orientation design paradigm is procedural programming. 
C)  The service-orientation design paradigm has been influenced by several established design paradigms and platforms.

Accepted Answer

A)  autonomous, increase 
B)  stateless, decrease 
C)  scalable, decrease 
D)  agnostic, increase

Question 15

Which of the following statements is false?

Accepted Answer

Question 18

Four IT managers from different organizations have chosen to adopt SOA. When subsequently interviewed, each was asked to explain why this decision was made. One of the IT managers is confused and chose to adopt SOA for the wrong reasons. Study the following responses and select the one that is not accurate:

Accepted Answer

A)  "SOA will help us increase the responsiveness of the organization as a whole. When our business encounters change, our IT department will be able to adapt and respond to this change more efficiently and effectively than before." 
B)  "SOA will help us increase the amount of value we get from the software programs we build as reusable services. Over time, this will allow us to improve the cost-effectiveness of IT as a whole."
