• Question 81:

  A developer is writing a Web service method that needs to accept multiple types of requests. Based on the request's content, the service performs time-consuming steps, such as verifying the user's account, checking credit ratings, and building a list of offers. Which two approaches are appropriate to use in this situation? (Choose two.)

  A. A synchronous, document-style approach.
  B. A synchronous, procedure-style approach.
  C. An asynchronous, document-style approach.
  D. An asynchronous, procedure-style approach.
  E. HTTP and HTTPS.
  F. SMTP or other asynchronous protocol.
  C. An asynchronous, document-style approach.
  F. SMTP or other asynchronous protocol.

• Question 82:

  In which order do LogicalHandlers and SOAPHandlers configured on a Web Service endpoint execute on an incoming message ? (Choose one)

  A. SOAPHandlers in the order specified in configuration are executed first and later the LogicalHandlers specified in the order get executed
  B. LogicalHandlers in the order specified in configuration are executed first and later the SOAPHandlers specified in the order get executed
  C. All the handlers are executed in the order specified in the configuration
  D. All the handlers are executed in the reverse order specified in the configuration.
  A. SOAPHandlers in the order specified in configuration are executed first and later the LogicalHandlers specified in the order get executed

• Question 83:

  A developer is asked to determine which Web services approach is correct for a new project. A SOAP-based Web service must be created and deployed in an environment where many customers will use it. These customers will be responsible for developing their own clients using different frameworks, based on the published WSDL. Which approach is correct to use first in this situation? (Choose one)

  A. Java, because the WSDL generated later will be more accurate
  B. WSDL, because the service and customers can benefit from the strongly typed schema
  C. Java, because the service must be efficient to support many customers
  D. WSDL, because tools allow existing classes to be easily mapped without modification
  B. WSDL, because the service and customers can benefit from the strongly typed schema

• Question 84:

  What is an accurate description of the handling of application exceptions thrown by a JAX-WS service endpoint?

  A. Application exceptions can be mapped to faults in WSDL.
  B. Application exceptions are NOT handled by JAX-WS SEI clients.
  C. Application exceptions are always propagated to JAX-WS clients as RemoteExceptions.
  D. Application exceptions are always propagated to JAX-WS SEI clients as WebServiceExceptions.
  E. Application exceptions are always propagated to JAX-WS SEI clients as SOAPFaultExceptions.
  A. Application exceptions can be mapped to faults in WSDL.

• Question 85:

  Which of the following is NOT true about configuring handlers on a Web Service endpoint? (Choose one)

  A. EE container automatically processes the handlers packaged in the application and configures it on the applicable endpoint
  B. Handlers can be configured using @HandlerChain annotation on endpoints configured with @WebService
  C. Handlers can be configured using @HandlerChain annotation on endpoints configured with @WebServiceProvider
  D. Handlers can be configured for endpoints in the deployment descriptor (webservices.xml)
  A. EE container automatically processes the handlers packaged in the application and configures it on the applicable endpoint

• Question 86:

  Given the following web service:

  

  How many web methods are there in the above web service ? (Choose one)

  A. 1
  B. 2
  C. 3
  D. 4
  E. 5
  D. 4

• Question 87:

  An airline built and deployed a back-end application to manage reservations. To support interoperability with as large a base of standalone client applications as possible, the services provided by this back-end application are exposed as XML-based restful web services. Management just added a new requirement that AJAX-based web application clients be supported, too. One of the developers suggested that it is enough to extend the existing application to support both XML-based and JSON-based restful web services. Assuming the developer is correct, choose the sentence that best describes an attempt to introduce this ability as this developer suggests (Choose one):

  A. The attempt will fail, because JAX-RS does not support both XML- and JSON- based restful services in parallel.
  B. The attempt will be trivial to implement, since JAX-RS just needs for the application to specify that both XML- and JSON-based interaction will be supported.
  C. The attempt can succeed, but it will require a significant amount of new code, since JAX-RS does support both XML- and JSON-based interaction - but not single resource can support both kinds of interaction simultaneously.
  D. The attempt will fail, because there is more to the difference between XML-based and JSON- based interactions than just the data representation used.
  B. The attempt will be trivial to implement, since JAX-RS just needs for the application to specify that both XML- and JSON-based interaction will be supported.

• Question 88:

  An engineer is studying the architecture of the JAXB implementation. What are three components in its design? (Choose three.)

  A. Schema compiler.
  B. Built-in SAX parser.
  C. Schema generator.
  D. Built-in DOM parser.
  E. Binding runtime framework.
  F. Schema interpreter.
  A. Schema compiler.
  C. Schema generator.
  E. Binding runtime framework.

• Question 89:

  A team of developers is designing RESTful Web services for a new application. What are three properties of the services? (Choose three.)

  A. They can be stateful.
  B. They can be stateless.
  C. Components communicate by exchanging representations of the resource.
  D. Components communicate by directly performing operations on the resource.
  E. They require WSDL service API definitions.
  F. Responses can be labeled as cacheable or non-cacheable.
  B. They can be stateless.
  C. Components communicate by exchanging representations of the resource.
  F. Responses can be labeled as cacheable or non-cacheable.

• Question 90:

  A team of developers is describing a set of endpoints in their new SOA application. Given the WSDL extract:

  

  Which statement is true about this WSDL extract?

  A. The extract is WS-I Basic Profile 1.1 compliant because both port element names are different.
  B. The extract is NOT WS-I Basic Profile 1.1 compliant because both port elements point to the same location.
  C. The extract is WS-I Basic Profile 1.1 compliant because both port elements point to different binding elements.
  D. The extract is NOT WS-I Basic Profile 1.1 compliant because it contains two port elements in the same service.
  B. The extract is NOT WS-I Basic Profile 1.1 compliant because both port elements point to the same location.
