Which statement is true about JAX-WS dynamic invocation?

D. Dynamic invocation requires the client to statically configure the Web service proxy.

E. The dynamic proxies provide dynamic invocation in JAX-WS.

E. HeaderError

F. InvalidHeader

Which two statements are true about elements in a WSDL document? (Choose two.)

B. Service is an abstract set of operations supported by one or more endpoints.

C. Message is an abstract description of an action supported by the service.

D. Operation is an abstract description of an action supported by the service.

E. Binding is a single endpoint defined as a combination of an operation and a network address.

F. Message is an abstract, typed definition of the data being communicated.

A stateful Web service is implemented as an EJB-based endpoint. What are two ways to maintain that state? (Choose two.)

A. by using URL re-writing

B. by adding a session cookie to the HTTP headers

C. by adding a conversation id to the SOAP headers

Which statement is true about .Net and WCF interoperability for this data?

A. Based on the fragment, enumerations map well between Java and .Net.

B. The subtle differences in the variable names make it clear these enumerations are NOT interoperable.

C. The XML schema reveals the type on the enumeration is lost across the platforms.

D. This exchange would be interoperable if the annotation @XmlEnum was applied to the Java method.

What are two reasons for choosing message-level security in a Web service? (Choose two.)

A. to support the use of SSL

B. to support multiple transport protocols

C. to selectively encrypt message content

D. to remove security information from SOAP headers

E. to support encrypted attachments

A Web service needs to encrypt certain SOAP headers when responding. Which statement about this encryption?

A. The Web service interaction layer is the appropriate place for such encryption.

B. The Web service processing layer is the appropriate place for such encryption.

C. Either the Web service interaction or processing layer is appropriate for such encryption.

D. Neither the Web service interaction nor processing layer is appropriate for such encryption.

E. Protocol-based encryption like HTTPS should be used to meet the requirements without code changes.
