• Question 72:

  A student developer has created a new library of math functions to share with friends in a linear algebra class. The developer is having difficulty getting people to come over to the dorm to see the new code library, so he decides to deploy it as a Web service so that everyone can enjoy the features via the Internet. One of the functions has this WSDL definition:

  D. It must send a SOAP fault back to the sender.
  E. It must NOT send a SOAP fault back to the sender.
  B. This is an asynchronous send.

  A. a Web service interface with one method per accepted XML document type for a purchase order
  B. a procedure-style Web service method that lists all data elements and all possible access control options.
  C. a document-style Web service method that accepts all types of XML documents representing purchase orders.
  D. a Web service interface with one method for each combination of data elements and the access control options.
  A. a Web service interface with one method per accepted XML document type for a purchase order
  C. a document-style Web service method that accepts all types of XML documents representing purchase orders.

• Question 74:

  Which two are defined by SAML? (Choose two.)

  D. the structure of the XML documents that transport authentication and authorization information between services
  E. an API in the form of the SAML reference implementation created by OASIS
  B. a protocol by which clients can request assertions about subjects from SAML authorities

• Question 77:

  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 technologies should they use? (Choose three.)

  A. SOAP
  B. REST
  C. Javascript
  D. XML
  E. JSON
  F. Java
  B. REST
  C. Javascript
  E. JSON

• Question 78:

  What are three best practices that can be implemented when generating WS-I Basic Profile compliant Web services? (Choose three.)

  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
  B. define data types early in the integration cycle
  D. test interoperability at every stage of development
  F. keep data types simple for speed and stability

• Question 79:

  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.
  C. Java should be used first because it is often the fastest and easiest approach.

• Question 80:

  Which two statements are true about creating a Web service with JAX-WS? (Choose two.)
