  B. SOAP services are self-documenting via the WSDL.
  C. Either SOAP or REST are suitable for the Web service.

• Question 53:

  A JAXR client has established connection with a UDDI registry and needs to get a service bindingfrom the registry. What is required to accomplish this task?

  A. find the appropriate concept and then find the service binding associated with that concept
  B. find the appropriate authentication token and then find the service binding associated with that authentication token
  C. find the appropriate organization, get the tModel associated with that organization, and then find the service binding associated with the tModel
  D. find the appropriate organization, find the services associated with that organization, and then find the service binding associated with the service
  D. find the appropriate organization, find the services associated with that organization, and then find the service binding associated with the service

• Question 54:

  Based on separation of concerns, which two are correctly implemented in the processing layer of a Web service? (Choose two.)

• Question 55:

  A developer is given a WSDL for an existing Web service. What is the correct sequence of steps that must be taken to use that Web service?

  B. use a utility (such as wsimport) to read the WSDL and generate a service endpoint interface
  C. register the WSDL with wsgen, bind to the stubs, and then call methods on the interface
  D. receive the service using RMI, parse the XML using JAXP, create Java objects using JAXR, and then return those Java objects
  B. use a utility (such as wsimport) to read the WSDL and generate a service endpoint interface

• Question 56:

  Which two statements are true about JAX-WS support for data bindings? (Choose two.)

• Question 58:

  Which two statements are true about the I-Stack and annotations technologies? (Choose two.)

  A. With 64-bit Java, JAXB compatible parameters are preferred for performance.
