Assume Reliable Messaging is used and the code is correct except for what is missing at line 10.
Which code fragment must be placed at line 10?
A. Close the port object with ((Closeable)port).close(); after testing result is positive.
B. Close the port with port.close();
C. Closing the port object is optional, but port.close(); will work.
D. Close the port object with ((Closeable)port).close();

9. minOccurs="0"/> 10. 11. Which two statements are true about .Net and WCF interoperability for this data? (Choose two.) A. The GregorianCalendar maps to an equivalent date type in both Java and .Net. B. .Net will generate code with the calendar as a string that functions as well as a date. C. .Net will generate code with the calendar as a string that is not type equivalent. D. Use of the @XmlSchemaType annotation causes .Net to properly map to a date. E. Casting in the case of WSIT services is an effective approach for the WCF client.
A purchase order Web service is designed to be synchronous, request-response, and HTTP- based. The existing service processes the request immediately. Because of new business requirements, the service can take up to ten days to perform a credit check before processing the order. Which two design changes need to be made? (Choose two.)
A. The client needs to use dynamic proxies instead of stubs.
B. The client needs to develop and deploy a Web service to accept callbacks.
C. The service only needs to change the WSDL from rpc-literal to document-literal.
D. The client and the service need to establish a mechanism to correlate the messages.
E. Given delays of up to ten days, a polling strategy is more efficient than callback.
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
Based on separation of concerns, which two are correctly implemented in the processing layer of a Web service? (Choose two.)
A. validation of XML documents
B. saving document contents in a database table
C. application of the business logic to the XML document
D. translation of incoming XML documents to their internal XML representations
E. a new SOAP message for exceptions during validation of XML
Which situation requires the client to use the Dispatch interface to access the Web service?
A. The client and the server are on different platforms.
B. The client has access to the portable artifacts, but not to the WSDL.
C. The client has access to the WSDL, but not to the portable artifacts.
D. The client will access a REST-based service.
Which statement is true about the SOAP 1.1 actor attribute?
A. It is ignored for HTTP.
B. It indicates the recipient of a header block.
C. It indicates the final recipient of the message.
D. It indicates which recipient processes the Body element.
E. SOAP 1.1 does not use the actor attribute.

Which statement is correct?
A. The message is SOAP-encoded because the encoding style is implied.
B. The message is RPC-encoded because in the absence of other specifiers, this is the WS-I default.
C. The message is document literal with type encoding, based on the schema provided.
D. The message is document literal wrapped because there is no encoded type information.
An organization has business logic implemented in EJB components. Current clients use container-managed, role-based security to access the business logic using RMI. Management has determined that the business logic must be made available to non-RMI clients using a Web service. Which container-managed Web service security mechanism must the development team use to allow Web service clients to use the current security model?
A. XKMS
B. XACML
C. XML Digital Signature
D. HTTP Basic Authentication
E. annotations mapped to the JAX-WS runtime
Which three techniques can be used to apply XML Digital Signatures to an XML document? (Choose three.)
A. use detached signatures, where the digital signature covers sibling elements or external data
B. use enveloping signatures, where the digital signature element encloses the data to be signed
C. use enveloping signatures, where the digital signature is a child element of the data to be signed
D. use enveloped signatures, where the digital signature is a child element of the data to be signed
E. use enveloping signatures, where the digital signature element is a child element of the data to be signed
