Q1. A Java EE application contains business logic composed of EJB beans. All current clients are Java applications accessing the business logic using RMI. Some clients are remote (running in different JVMs) and some are local (running in the same JVM). Which of the following two occur if EJB components are exposed as Web services? (Choose two.)
A. New client applications can be built using the published WSDL to access existing business logic
B. Current remote clients must switch from RMI to web service access.
C. New remote clients can access business logic using RMI or web service access
D. New local clients must access business logic using only RMI
E. New clients must only be written in java to access business logic
Answer: AC
Q2. Given the JAX-RS root resource class fragment: Choose the statement that best describes the configuration that would be required to support the access control constraint shown:
A. No further configuration is required - the JavaEE runtime will pick up the security constraint and configure the web container to match.
B. The developer will have to configure the web container to require authenticated access to the URLs corresponding to this resource, so the proper information can be propagated to the EJB container.
C. The developer will have to turn on authentication in the web container configuration file, so that all incoming requests are authenticated in order to be processed.
D. The developer will have to configure the web container to require authenticated access to the URLs corresponding to this resource, and then map web-tier roles to ejb-tier roles, since the JAX-RS and EJB runtimes cannot use the same set of roles.
Answer: B
Q3. A company has contracted a developer to create their new accounting system. The system the developer will replace runs a monolithic web application using one web server and one database server.

What are three characteristics of services in the proposed Service Oriented Architecture? (Choose three.)
A. Services are coarse grained.
B. Services are finely grained.
C. Services are loosely coupled.
D. Services are tightly coupled.

Answer: ACF
Q4. A developer is tasked with analyzing a new Web services project and must decide to use either SOAP or REST.

A. The SOAP approach consists of resources identified by unique URIs.
B. SOAP services are self-documenting via the WSDL.
C. Either SOAP or REST are suitable for the Web service.
D. REST fully documents data types via the functional interface GET and POST.

resource.accept("value").type("application/json").get(Value.class);
D. WebResource resource = client.resource("/res/value");
Value val = resource.get(Value.class);
Answer: A
Q6. Which two statements are true about the interoperability of Web services developed using the Java EE 6 platform? (Choose two.)
A. Interoperability is improved by restricting access only to Java clients.
B. EJB-based endpoints are more difficult for .NET clients to access.
C. Only servlet-based endpoints are used when exposing services to non-Java clients.
D. The signature of Web service methods is limited to parameters and return types that are concrete types and simple arrays of concrete types.
E. The service must be published in both the .NET and Java UDDIs.
F. Testing for WS-I Profile conformance improves interoperability.
Answer: DF
Q7. A developer is writing a Web service method that needs to accept multiple types of requests. Based on the request's content, the service performs time-consuming steps, such as verifying the user's account, checking credit ratings, and building a list of offers. Which two approaches are appropriate to use in this situation? (Choose two.)
A. A synchronous, document-style approach.
B. A synchronous, procedure-style approach.
C. An asynchronous, document-style approach.
D. An asynchronous, procedure-style approach.
E. HTTP and HTTPS.
F. SMTP or other asynchronous protocol.
Answer: CF
Q8. 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.
Answer: C
Q9. 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:
<portType name="MyMathLib"><operation name="incCtr"><input message="tns:incCtr"/></operation></portType>
Which two statements are true about this Web service? (Choose two.)
A. This is an asynchronous receive.
B. This indicates a one-way message exchange pattern
C. The client must use SOAPFaultException to display any errors.
D. It must send a SOAP fault back to the sender.
E. It must NOT send a SOAP fault back to the sender.
Answer: BE

C. "/InvoiceService"
D. "/InvoiceWebService"
Answer: C
