IBM Assessment: Web Services Development for IBM WebSphere Application Server V7.0 Sample Questions:

1. Refer to WSDL extract in the exhibit. What does the soap: binding element specify?

A) The message will be in an XML document
B) The binding is defined by theNewWSDLFile type
C) SOAP will be used as a transport protocol
D) The binding is bound to the SOAP protocol format

2. Which of the following is TRUE about specifying the SOAP version in JAX-WS?

A) The JAX-WS @Binding Type annotation of SOAP12 indicates to expose the Web service via SOAP 1.2 on both HTTP and JMS
B) A Web service implementation defined with a JAX-WS @Web Service annotation defaults to expose the endpoint via SOAP 1.1 only.
C) A Web service implementation defined with a JAX-WS @Web Service annotation defaults to expose the endpoint via both SOAP 1.1 and SOAP 1.2.
D) The JAX-WS @Binding Type annotation of SOAP12HTTP_BINDING indicates to expose the Web service via SOAP 1.2
E) A Web service implementation defined with a JAX-WS @Web Service annotation defaults to expose the endpoint via SOAP 1.2 only.

3. A developer has finished working on the implementation of a Web service using IBM Rational Application Developer V7.5. What are the appropriate ways to create a policy set with just an LTPA token?

A) Make a copy of the "LTPAWSSecurity default" policy set in IBM Rational Application Developer V7.5 workspace and use the policy set editor to disable WS-Security protection in the copy.
B) Use the Policy Set editor in IBM Rational Application Developer V7.5 to create a new policy set with an LTPA token
C) Use the Administrative Console to create a new policy set with an LTPA token,export it and import into IBM Rational Application Developer V7.5
D) Make a copy of the "LTPAWSSecurity default" policy set using wsadmin scripts and disable WS-Security protection in the copy, export the copy and import into IBM Rational Application Developer V7.5
E) Make a copy of the "LTPAWSSecurity default" policy set using Administrative Console and disable WS-Security protection in the copy, export the copy and import into IBM Rational Application Developer V7.5

4. An RPC/encoded Web service experiences poor performance at high message volumes. What can a developer do to improve this performance?

A) Use document/literal encoding
B) Redesign to use more granular messaging
C) Use binary encoding
D) Turn off marshalling
E) Use RPC/literal encoding

5. Refer to the exhibit.

A developer has a JAX-WS Web service provider implementation which has two operations, as shown in the exhibit. The developer wants to enable LTPA with HTTPS protection for the web service. This can be accomplished by attaching:

A) A policy set with "WS-Security" policy LTPA enabled and "SSL transport" policy to the service
B) A policy set with "WS-Security" policy LTPA enabled to the service and set to "CONFIDENTIAL" in web.xml
C) A policy set with "WS-Security" policy LTPA enabled and "SSL transport" policy to the operation "B" only
D) A policy set with "WS-Security" policy LTPA enabled and "SSL transport" policy to the port
E) Two policy sets: one with LTPA enabled; and one with "SSL transport" policy to the service
F) A policy set with "WS-Security" policy LTPA enabled and "SSL transport" policy to the operation "A" only
