  A. proxy = new StockQuoteService().getStockQuoteProvider()
  B. proxy = new StockQuoteService().getStockQuoteProvider(new AddressingFeature())
  C. proxy = new StockQuoteService().getStockQuoteProvider(new AddressingFeature(false))
  D. proxy = new StockQuoteService().getStockQuoteProvider(new AddressingFeature(false, true))
  A. proxy = new StockQuoteService().getStockQuoteProvider()
  B. proxy = new StockQuoteService().getStockQuoteProvider(new AddressingFeature())

• Question 32:

  XML Signature and XML Encryption provide the foundation for message level security in Web services. Which statement about XML signature is NOT true?

  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
  C. use enveloping signatures, where the digital signature is a child element of the data to be signed

• Question 33:

  Choose three ways to enable MTOM on a web service endpoint deployed in an EE container ? (Choose three)

  A. enabled by the container automatically
  B. by specifying @MTOM annotation on the endpoint's class
  C. by specifying in webservices.xml deployment descriptor
  D. by specifying a wsoma:MTOM policy in WSDLE. by specifying element in sun- jaxws.xml
  B. by specifying @MTOM annotation on the endpoint's class
  C. by specifying in webservices.xml deployment descriptor
  D. by specifying a wsoma:MTOM policy in WSDLE. by specifying element in sun- jaxws.xml

• Question 34:

  Given this class:

  

  Choose the statement that best describes the potential to write a client implemented using JAX- WS to interact with the JAX-RS (restful) web service defined by this class (Choose one):

  A. It is impossible, since JAX-WS requires that the underlying interaction be SOAP-based, and JAX-RS does not support SOAP.
  B. It is impossible, since JAX-RS does not support the same extension mechanism via JAX-WS Handlers that JAX-WS supports.
  C. It is possible, since the JAX-WS API can be used to create a client that uses a simple raw XML protocol to interact with a service at a given URL.
  D. It is possible, since a JAX-WS proxy Port type can be generated to use a simple raw XML protocol to interact with a service at a specific fixed URL.
  C. It is possible, since the JAX-WS API can be used to create a client that uses a simple raw XML protocol to interact with a service at a given URL.

• Question 35:

  D. HTTP Basic Authentication

• Question 36:

  B. The sender creates a digital signature using its own private key and sends that signature along with the original document.
  C. The sender creates a digital signature using its own public key and sends that signature along with the original document.
  D. The receiver verifies that the message matches the digital signature using the sender's public key.
  B. The sender creates a digital signature using its own private key and sends that signature along with the original document.
  D. The receiver verifies that the message matches the digital signature using the sender's public key.
