IBM C2040-423 Online Questions & Answers

• Question 41:

  Arthur developed two portlet applications to support the same event-- the choosePerson event. This event uses the "http://example.ibm.com/portlets" namespace, and its payload type is the com.ibm.example .Person class.

  Arthur deployed one portlet from each portlet application to the same portal page. He also wired one portlet (Portlet A) as the event source and the other portlet (Portlet B) as the event target. When Arthur tests the portlet communication, he

  does not see that the com. ibm. example. Person object was transferred to Portlet B after the event was fired from Portlet A.

  How can Arthur resolve this problem for optimal performance?

  A. Ensure that the "Global" check box is selected on the Wire Configuration page.
  B. Update the com. ibm. example. Per son class to support serialization and XML serialization by adding JAXB annotations.
  C. Move the com. ibm. example. Person class out of the two web archive (WAR) files and into an IBM WebSphere Application Server shared library that is used by both WAR files.
  D. Ensure that "http://example.ibm.com/portlets" namespace is specified as the direct namespace for the event declaration for both portlet.xml files, rather than the default namespace for each portlet.xml file.
  D. Ensure that "http://example.ibm.com/portlets" namespace is specified as the direct namespace for the event declaration for both portlet.xml files, rather than the default namespace for each portlet.xml file.

• Question 43:

  Rachel needs to configure access to her company's mail system by using a portlet. The company requires users to be prompted for their user name and password the first time they access their mail. This information is then stored for future access.

  What type of credential vault slot should Rachel use?

  A. system slot
  B. shared user slot
  C. portlet shared slot
  D. administrative slot
  C. portlet shared slot

• Question 44:

  Isabel wants to display different content automatically to users, depending on their group access. Which IBM WebSphere Portal feature should Isabel use to configure this objective?

  A. dynamic Ul
  B. preferences
  C. customization
  D. personalization
  D. personalization

  ---

  SyncML DM is based on the SyncML protocol and is designed to enable the customizing, personalization, and servicing of mobile device, taking into account the same limitations as SyncML DS does for mobile environments.

• Question 45:

  Rudy wants to delete a portal page by using the Controller service provider interface (SPI).

  He wrote the following code:

  final Locator locator = cmController.getLocator(); final ContentPage page = (ContentPage) locator.findByllniqueName("MyPage");

  cmcontroller.delete(page);

  How can he use this code to delete the page?

  A. This code alone will delete the page.
  B. There is not a delete method so this code is not valid.
  C. He needs to find the page by URL instead of UniqueName.
  D. He needs to commit the controller to persist the modification.
  A. This code alone will delete the page.

• Question 46:

  Which model is supported by the Remote Model REST service?

  A. PortletModel
  B. ContextModel
  C. ThemeListModel
  D. Language ListModel
  A. PortletModel

  ---

  Remote Model SPI REST service The Remote Model SPI gives you access to portal models through REST services. It allows you to obtain and modify portal resources that are exposed by some of the models of the model SPI remotely, that is from clients that are outside the JVM of the server. This is achieved by means of REST services.

• Question 47:

  Sam wants to create a portlet that uses a custom portlet mode that is not defined in the JSR 286 specification.

  After implementing the correct methods, what additional step must he do to use a custom portlet mode?

  A. Add the custom portlet mode to the portlet deployment descriptor.
  B. Add a resource bundle to the portlet that has the name of the custom portlet mode.
  C. Configure the portlet after installation to map the custom portlet mode to the server- defined portlet mode.
  D. Enable the specific custom portlet mode at the container level by setting the correct property in the resource environment provider.
  A. Add the custom portlet mode to the portlet deployment descriptor.

• Question 48:

  Which statement is true regarding JSR 286 event support in IBM WebSphere Portal?

  A. Events can be wired to IBM API cooperative portlets.
  B. Events can be wired to JSR 168 cooperative portlets.
  C. Events cannot be used in tandem with public render parameters.
  D. When the "Global" check box is set on the wires page. JSR 286 event processing is automatic; wires are not needed and. therefore, are ignored.
  B. Events can be wired to JSR 168 cooperative portlets.

  nteroperability between JSR 286 portlet events and JSR 168 cooperative portlets By concept, cooperative portlets are similar to JSR 286 portlet events. Both concepts describe publish/subscribe communication patterns that are based on typed information that is published and received by portlets and propagated via communication links.

  Because the concepts are quite similar, the portal supports data exchange between JSR 168 cooperative portlets and JSR 286 portlets that support events. This means that you can extend an existing setup using JSR 168 cooperative portlets with new JSR 286 portlets and that you can smoothly migrate individual cooperative portlets to the new API without losing communication possibilities.

• Question 49:

  George is using the PortletStateManager getPortletStateManager ( PortletRequest request, PortletResponse response) method in his portlet code.

  Where should George use this method in his code for best performance?

  A. init
  B. doEdit
  C. doview
  D. processAction
  B. doEdit

  ---

  :

  PortletStateManager getPortletStateManager( PortletRequest request, PortletResponse response)

  This method returns a PortletStateManager object which you can use during action processing and rendering (for example in the processAction method, doView method, doEdit method, etc.). The PortletStateManager interface adds

  additional methods to extend the generic StateManagerService interface, which, for example, allows you to directly read the current request-specific navigational state of the portlet (portlet mode, window state, and render parameters).

• Question 50:

  James is developing a portlet and wants to share the cache entry across all users upon certain conditions.

  What is a valid way to accomplish his goal?

  A. Add the conditions in the doView method and set the cache scope to public in the request.
  B. Add the conditions in the doview method and set the cache scope to public in the response.
  C. Add the conditions in the doHeade rs method and set the cache scope to public in the request.
  D. Add the conditions in the doHeaders method and set the cache scope to public in the response.
  D. Add the conditions in the doHeaders method and set the cache scope to public in the response.
