Sample Questions:Which of the following statements is true? Select the correct answer.WS-Reliable Messaging standardizes reliability levels associated with databases required to persist state data.WS-Reliable Messaging standardizes the issuance and delivery of positive and negative acknowledgement messages.WS-Reliable Messaging standardizes SOAP headers related to atomic transactions with rollback features.WS-Reliable Messaging standardizes the expression of service composition logic, but only for SOAP based Web services.Which of the following statements is true? Select the correct answer.An enterprise service bus commonly provides service broker-related features that allow two services using different data models (that represent the same business document) to communicate with each other.An enterprise service bus commonly provides service broker-related features that allow two services using different communication protocols to communicate with each other.An enterprise service bus commonly provides service broker-related features that allow two services to communicate even though they use different communication protocols and different data models (that represent the same business document).All of these statements are true.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.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.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 APPLYA 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.Which of the following statements is true? Select the correct answer.Individual service contracts do not need to be published for SOAP-based Web services. Instead, they use a uniform contract.Individual service contracts do not need to be published for REST services. Instead, they use a common uniform contract.Components provide published contracts, but when building services as components, components must use a uniform contract instead.None of these statements are true.Which of the following statements is false? Select the correct answer.The WS-I is an industry standards organization that provides basic profiles to help foster interoperability among solutions based on XML and Web services industry standards.OASIS is an industry standards organization that has developed a number of important technology specifications, including WS-BPEL and UDDI.The W3C is a standards organization that has developed a number of important technology specifications, including SOAP, WSDL, and WS-Addressing.The OAS-C is an industry standards organization that has developed a number of important technology specifications, including WS-Security and XML Schema.
