Question 3: Which statement best describes the relationship between a SOA Service and service
Infrastructure?
A. Service infrastructure is a primary part of an SOA Service.
B. Service Infrastructure exposes the Service Interface and may satisfy some capabilities of the
Service Implementation.
C. Service infrastructure fulfills the Service Contract.
D. A SOA Service depends on the service infrastructure to satisfy some required capabilities.
E. A SOA Service uses the service infrastructure to generate the Service Interface.
Correct Answer: B
Explanation: The Service Infrastructure side typically provides the Service enablement
capabilities
for the implementation. These capabilities may include, exposing the interface as a
Web Service, handling SLA enforcement, security, data formatting, and others. Service
infrastructure should be utilized when possible, as it reduces the burden on Service
providers, from an implementation standpoint.
