Q33. 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.

Q34. Given the two classes:
Choose the option that best evaluates the example:

C. This is an invalid example, because singleton EJBs used as JAX-RS resources must explicitly state what locking strategy they will require.
D. This is an invalid example, because the JAX-specification only allows root resource types to also be EJBs.
