Java Platform, Enterprise Edition 6 Web Services Developer Certified Expert Exam

Question No: 51 – (Topic 0)

A purchase order Web service is designed to be synchronous, request-response, and HTTP-based. The existing service processes the request immediately. Because of new business requirements, the service can take up to ten days to perform a credit check before processing the order. Which two design changes should be made? (Choose two.)

  1. The client needs to use dynamic proxies instead of stubs.

  2. The client needs to develop and deploy a Web service to accept callbacks.

  3. The service only needs to change the WSDL from rpc-literal to document-literal.

  4. The client and the service need to establish a mechanism to correlate the messages.

  5. Given delays of up to ten days, a polling strategy is more efficient than callback.

Answer: B,D

Question No: 52 – (Topic 0)

An enterprise has a requirement to create a Web service to accept purchase orders. The order data contains some authorization information that is specific to each order (such as, who can access which parts of the order). Keeping in mind future enhancements in types of orders that the enterprise needs to accept, which two design solutions provide the most flexibility? (Choose two.)

  1. a Web service interface with one method per accepted XML document type for a purchase order

  2. a procedure-style Web service method that lists all data elements and all possible access control options

  3. a document-style Web service method that accepts all types of XML documents representing purchase orders.

  4. a Web service interface with one method for each combination of data elements and the access control options

Answer: A,C

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. Technical requirements state the developer must write the business logic in Java, deploy to the application server and push the presentation logic onto the web servers. What are three characteristics of services in the proposed Service Oriented Architecture? (Choose three.)

  1. Services are coarse grained.

  2. Services are finely grained.

  3. Services are loosely coupled.

  4. Services are tightly coupled.

  5. Clients must be implemented in the Java technology.

  6. Services are platform agnostic, network-addressable web APIs.

Answer: A,C,F

Question No: 54 – (Topic 0)

Which two statements are true about WSIT client development and using the WSIT configuration file? (Choose two.)

  1. Client configuration files do NOT contain information security features, such as authentication.

  2. The file contains the URL for the WSDL.

  3. To maintain interoperability, the configuration file must not name packages.

  4. A WSIT client uses the file as a WSDL proxy is available from any WSIT compliant service.

  5. The wsimport tool uses the file to access the WSDL and build stubs to access a service.

Answer: B,E

Question No: 55 – (Topic 0)

What are two valid facts about WS-I? (Choose two.)

  1. The I-Stack is a great development tool.

  2. The WS-I promotes and supports generic protocols for the interoperable exchange of messages.

  3. The WS-I governs languages and protocols such as SOAP, WSDL, and UDDI.

  4. The WS-I specifies specific rules that address either weaknesses in component specifications or issues of how to combine the collected


  5. The WS-I has been a guiding force in creating StAX.

Answer: B,D

Question No: 56 – (Topic 0)

According to the WS-I Basic Profile 1.0a, what is true about the SOAP 1.1 encodingStyle attribute?

  1. It can occur anywhere in a message.

  2. It can only be declared on children Header elements.

  3. It can be declared on any children of the Body elements of rpc-literal messages.

  4. It cannot be used with elements qualified by the http://schemas.xmlsoap.org/soap/envelope namespace.

  5. WS-I Basic Profile 1.1 does NOT give any guidance because encodingStyle is a SOAP

1.1 attribute.

Answer: D

Question No: 57 – (Topic 0)

Choose the types of Enterprise Beans that can be made into JAX-RS root resources (Choose two):

  1. Stateful Session Beans

  2. Stateless Session Beans

  3. Message-Driven Beans

  4. Singleton Beans

Answer: B,D

Question No: 58 – (Topic 0)

Choose the statement that best describes the use of Enterprise Beans as JAX-RS root resources:

  1. An Enterprise Bean can be made a JAX-RS root resource only if EJB-specific features such as transaction management or security validation

    are not used.

  2. JAX-RS imposes no limitations on the characteristics ofthose Enterprise Beans that can be exposed as JAX-RSresource classes.

  3. An Enterprise Bean that is exposed as a JAX-RS root resourcecan no longer be used directly as a remote bean itself – thebean

    implementation class can be accessed via the remote EJBdistributed framework (RMI), or a JAX-RS root resource, but not both concurrently

    within the same application.

  4. An Enterprise Bean that is exposed as a JAX-RS root resource supports all the same features as a JAX-RS resource that it supports as an


Answer: B

Question No: 59 – (Topic 0)

Where can a developer specify confidentiality or integrity constraints on communications with a Enterprise Bean exposed as a JAX-RS root resource?(Choose one)

  1. As annotations on the EJB exposed as a root resource.

  2. In the deployment descriptor for the EJB exposed as a root resource.

  3. In the deployment descriptor for the web application that is hosting the JAX-RS resource.

  4. In the vendor-specific configuration file for the container that is hosting the JAX-RS resource.

Answer: C

Question No: 60 – (Topic 0)

Given this class:

Ensurepass 2018 PDF and VCE

Choose the statement that best describes the potential to write a client implemented using JAX-WS to interact with the JAX-RS (restful) web service defined by this class (Choose one):

  1. It is impossible, since JAX-WS requires that the underlying interaction be SOAP-based, and JAX-RS does not support SOAP.

  2. It is impossible, since JAX-RS does not support the same extension mechanism via JAX-WS Handlers that JAX-WS supports.

  3. It is possible, since the JAX-WS API can be used to create a client that uses a simple raw XML protocol to interact with a service at a given URL.

  4. It is possible, since a JAX-WS proxy Port type can be generated to use a simple raw XML protocol to interact with a service at a specific fixed URL.
