Question 1

Frances is debugging an iWidget that should show a loader bar until markup is generated and shown, leveraging only lifecycle functions. Right now, she can only see the loader bar, but nothing else happens in the iWidget. She has verified that all dependencies have loaded properly and that the elements have rendered. What should she verify next?

A. Verify that the onUnload method is properly modifying the page content after loading completes.

B. Verify that the readyMarkup method is properly implemented.

C. Verify that the view is a supported mode for the iWidget.

D. Verify the onLoad method kicked off background functions needed to render the markup.

Correct Answer: D

Question 2

Hershel wants to programmatically check if specific users have access to his company's new portlet application, in order to show a message in another portlet asking them to purchase a subscription. He is trying to do so with the least amount of performance overhead. What would be the best way for Hershel to accomplish this?

A. He should read role assignments using the com.ibm.portal.ac.RoleData interface and ensure portlet caching is enabled.

B. He should use AccessControlRuntimeModel or AccessControlGlobalRuntimeModel to verify explicit role assignments.

C. He should use the com.ibm.portal.ac.RoleData interface to verify explicit role assignments.

D. He should use the com.ibm.portal.ac.UserRoles interface to verify explicit role assignments.

Correct Answer: B

Question 3

In the case of a processAction or serveResource call, what is the expected behavior if an action or resource parameter has the same name as a public render parameter?

A. The public render parameter values must be the last entries in the parameter value array.

B. The public render parameter takes precedence and overwrites the value of the action/resource parameter.

C. The public render parameter is ignored.

D. The public render parameter is appended with a unique identifier to distinguish it from the action/resource parameter.

Correct Answer: A

Question 4

Corrie needs to create several iWidgets that will interact with each other. She is evaluating the mechanisms that she can use to share state information between the iWidgets. Which one of the following options is the best way to accomplish this?

A. Declare the state sharable in the ItemSet definition and register listeners in the individual iWidgets to be informed when shared state changes.

B. Implement public render parameters.

C. Use the JSR 286 defined event and payload mechanism.

D. Store state information in the user's session.

Correct Answer: A

Question 5

Given the following code in the portlet.xml file, what line of code returns the value of the "test" initparam. <portlet-class>MyPortlet</portlet-class> <init-param> <name>test</name> <value>test_init_parameter</value> </init-param>

A. renderRequest.getPortalContext().getInitParameter("test");

B. renderRequest.getInitParameter("test");

C. renderResponse.getInitParameter("test");

D. portletConfig.getInitParameter("test");

Correct Answer: D

Question 6

Roger has been discussing iWidgets with a prospective client and has been highlighting certain aspects of the specification. Which of the following statements is false and thus ill-advised?

A. Three modes are defined in the iContext Constants (VIEW, EDIT and HELP). An iWidget does not need to support all three modes.

B. The iDescriptor is a special ManagedItemSet which is always persisted by the iContext.

C. iScope is a mechanism to support encapsulation of an iWidget's assests.

D. Overall page management components are provided by the iContext. These include iWidget coordination, page layout and controls, andbackend service interaction.

Correct Answer: B

Question 7

What does the collaborative services API allow the portlet developer to do?

A. The API provides the IBM Connections business cards capability to a custom portlet.

B. The API provides person tags to custom portlets.

C. The API allows the user to connect to social services such as Twitter and Facebook for custom portlets.

D. The API gives the user access to Microsoft Exchange and IBM Lotus Notes inboxes when developing custom portlets.
