Question 7

When two compatible SOAP-based Web services need to exchange an XML document that is compliant with the XML schema shared by both services, then: Select the correct answer.

Select an option, then click Submit answer.

  • ○

    A data model transformation technology, such as XSLT, must be used to enable the data exchange.
  • ○

    A new XML schema must be created to overcome the disparity between how each service defines the data model for the XML document.
  • ○

    A WS-Policy definition must be created to establish rules that address any differences in the XML document exchange.
  • ○

    None of the above.
Question 8

Like components, SOAP-based Web services can be developed using vendor tools. Unlike components, the communications framework established by SOAP-based Web services can be based on industry standards thereby remaining vendor-neutral. Select the correct answer.

Question 9

Identify what is wrong with the following statement: "I have a single Calculator component that provides basic math functions. I'm exposing this component as a component-based service for internal service consumers that are also component-based. I'm exposing this component as a SOAP-based Web service for internal and external service consumers that support SOAP messaging. I'm also exposing this component as a REST service for external service consumers that prefer to access its functions via HTTP methods. I'm also exposing this component as a service agent for service consumers that support explicit invocation via a service contract." SELECT ALL THAT APPLY

Select an option, then click Submit answer.

  • ○

    A single component cannot be exposed as a component-based service, a SOAP-based Web service and a REST service at the same time.
  • ○

    SOAP-based Web service consumer programs cannot be both internally and externally located.
  • ○

    The uniform contract required by REST services does not support the use of HTTP methods.
  • ○

    Service agents are event-driven and are therefore not explicitly invoked via a service contract.
