IBM Developing Portlets and Web Applications with IBM Web Experience Factory 8.0 認定 LOT-927 試験問題:

1. Yolanda needs to add an element to an XML structure that is interacting with an object in IBM Web Experience Factory. Assuming the XML structure exists, what would be the method that she should call to add a new child element?

A) setName("ElementName")
B) setNameWithText("ElementName")
C) addChildElement("ElementName")
D) addChildWithText("ElementName")

2. Jose is designing web services that will return very large record sets (in the 1000's). He is also designing an IBM Web Experience Factory application to consume them and plans to use Web Experience Factory's Paging features to paginate over the large record sets. How should paging be configured for the web services?

A) He should consider using The Chunked Data Retriever builder, which allows you to specify a start index and fetch size before invoking a web service.
B) He should use enable the Web Service Call to return a DataRetriever and then add a Paging Assistant builder and point to the variable created by the results of the web service call.
C) Jose should consider implementing a start index and fetch size parameter in his underlying web services that return large record sets. Then in Web Experience Factory he can implement the DataRetriever interface which enables the Paging Assistant builder to return "chunks" from the underlying service rather that marshalling the entire record set into the application server's memory.
D) He should simply enable paging in the Data Column Modifier builder. Web Experience Factory automatically chunks the data from the backend web service into the app server memory.

3. Dave wants to see information about web service parameters, URL endpoint, and SOAP envelope. What must he do to obtain this data for a particular Web Service Call builder?

A) There is no way for him to get this information other than contacting customer support.
B) He must set the Logging field to All in the Web Service builder to log this information to the WEB-INF/logs/debugTracing.txt file.
C) He must use a Java debugger to get this information.
D) This information is always printed to the standard output console log without any developer intervention required.

4. Isaac is building a web service consumer outside the context of IBM WebSphere Portal. His consumer needs access to raw data returned by a Service Definition builder in a provider model on another server. How can the WSDL be generated and provided?

A) Provide the namespace for the application, and the path to the generated WSDL file on the file system.
B) Define the WSDL in the SQL DataSource builder, in the Advanced section.
C) Select the generate WSDL check box in the Service Consumer and locate the WSDL file in the project.
D) Use the check box for WSDL generation in the Service Definition builder call and reference the generated WSDL by URL to the provider model with the suffix /Action!getWSDL.

5. Willow wants to get all the text that is created by the Data Services User Interface (DSUI) builder into a resource bundle for globalization. How would she do this?

A) There is no globalization support available for pages created by DSUI.
B) Enter a valid resource bundle name in the appropriate DSUI builder field, and it automatically exports all the strings and keeps the resource bundle and the builder fields synchronized.
C) DSUI always uses a resource bundle; it is a required field in the builder when she created it.
D) From the Design view, right-click any of the pages it created and select Export Resource. The DSUI builder ensures that data from all the pages is exported.
