C)The end user's access to data should be limited to a specific geographic area due to security reasons.
D)Multi-channel service delivery should be available exclusively to end users and not customers.

Accepted Answer

An SOA philosophy requires that your organization view its end users of IT (i.e. ,employees within the organization)just as it does external customers.This is mainly achieved through a fully integrated enterprise resource planning (ERP)system that meets every application software and information need of each and every employee.

Question 11

Which of the following is true of service-oriented architecture (SOA)?
A)It is a perspective that focuses on acquiring brand new systems.
B)It builds applications from non-reusable blocks of code.
C)It focuses on the development,use,and reuse of services.
D)It defines the source code for application programming interfaces.

Accepted Answer

A service-oriented architecture (SOA)is a software architecture perspective that focuses on the development,use,and reuse of small self-contained blocks of code (called services)to meet all the application software needs of an organization.

Question 12

Genesis Technologies has adopted an SOA approach to systems development.A new "disruptive" technology,Senstor,has recently been launched in the market which promises to provide significant benefits to software companies that focus on collaborative process.In such a scenario,how is Genesis Technologies most likely to react?
A)It will delay the decision making process with regard to the adoption of the new technology.
B)It will continue to use its existing systems instead of trying out the new technology.
C)It will use its resources efficiently to adapt itself to the new technology.
