Q9. If you are developing a Web Service starting from WSDL 1.1, how would you declare in wsdl that the Web Service requires the use of Addressing in a standard and interoperable way.
A. Declare a policy as
<wsp:Policy>
<wsam:Addressing wsp:Optional="true">
<wsp:Policy/>
</wsam:Addressing>
</wsp:Policy>
and attach it the corresponding wsdl:portType so that it applies to all the wsdl:operations in its
scope.
B. Declare a policy as
<wsp:Policy>
<wsam:Addressing wsp:Optional="true">
<wsp:Policy/>
</wsam:Addressing>
</wsp:Policy>
and attach it the corresponding wsdl:binding so that it applies to all the wsdl:operations in its
scope.
C. Declare a policy as
<wsp:Policy>
<wsam:Addressing>
<wsp:Policy/>
</wsam:Addressing>
</wsp:Policy>
and attach it the corresponding wsdl:binding so that it applies to all the wsdl:operations in its
scope.
D. Declare a policy as
<wsp:Policy>
<wsam:Addressing>
<wsp:Policy/>
</wsam:Addressing>
</wsp:Policy>
and attach it the corresponding wsdl:service so that it applies to all the wsdl:ports in the service scope.

Q12. A developer is asked to consult on a Web services project and assist the team with a good design approach on a new project. The team members disagree on whether to use WSDL or Java first. Several members are skilled with XML and see a schema and WSDL as the correct place to start. The team has also learned the deadline for this project has been moved up and another team plans to reuse their code. Which statement is true about the proper course of action to take in this situation?
A. Java should be used first because it is a strongly typed language and will result in a robust WSDL.
B. WSDL should be used first because it will make the code easier to reuse for the other team.
C. Java should be used first because it is often the fastest and easiest approach.
D. WSDL should be used first because the team knows XML Schema.

Q13. A company is refactoring an existing website to use Web services clients. The application retrieves lists of parts and displays them to the users in a browser window. Previously, the data was stored as files on the web server and, in order to access the files, the user would simply click on a hyperlink. Now the data must be dynamically generated via a service that another developer has created. They want the easiest way to refactor their website to use Web services. Which three client-side technologies should they use? (Choose three.)
A. SOAP

C. Javascript
D. XML
E. JSON

Q14. HTTP clients can provide authentication information to the server via the "Authorization" header in the HTTP request. Choose the alternative, if any, that would serve as the definition for a resource method that would allow a JAX-RS resource to obtain this authentication data (Choose one):
A. It is impossible for a JAX-RS resource to obtain this information, since low-level HTTP data is not presented to the JAX-RS application layer.
B. @GET @Path("/authInfo")
public String getAuthInfo( String authenticate ) {
return authenticate;
}
C. @GET @Path("/authInfo/{AUTHENTICATE}")
public String getAuthInfo(
@PathParam("Authorization") String auth ) {
return authenticate;
}
D. @GET @Path("/authInfo")
public String getAuthInfo(
@HeaderParam("Authorization") String auth ) {
return authenticate;
}
Answer: D

A. Send arrays of nulls to ensure .NET and Java clients receive the same data.
B. Define data types early in the integration cycle.
C. Use complex data types to reduce the number of items exchanged.
D. Test interoperability at every stage of development.
E. Insert conformance headers in all SOAP messages.
F. Keep data types simple for speed and stability.
Answer: BDF
