Rick creates a Server-Side JavaScript library, and defines a few global variables at the beginning of the library. The JavaScript in his XPage and in the JavaScript library modify those global variables. The server the application runs on is heavily used, and the application settings are set to Keep Pages on Disk for best scalability. When the application executes, what is likely to happen?

• A.The application will run, but the values of the globally defined variables may be lost when the server's JVM garbage collects variables, causing unexpected results.
• B.The application will generate an error because you can not declare global Server-Side JavaScript variables
• C.The application will perform as expected.
• D.The application will run, but every partial or full refresh will reset the values of the global variables when it reloads the Server-Side JavaScript library.

Jeremy wants all of the dijit.Dialog boxes in his application to call a client side JavaScript function called "validateForm" whenever they are hidden. What is the best solution?

• A.Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
  using the following code:
  /**
  *Custom Dojo Control
  */
  dojo.provide('com.myco.widget.Dialog');
  dojo.require('dijit.Dialog');
  (function(){
  dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
  onHide: validateForm
  })
  }());
  /**
  *Initialization code
  */
  var dialog = new com.myco.widget.Dialog();
• B.Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
  using the following code:
  /**
  *Custom Dojo Control
  */
  dojo.provide('com.myco.widget.Dialog');
  dojo.require('dijit.Dialog');
  (function(){
  dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
  onHide: validateForm
  })
  }());
  /**
  *Initialization code
  */
  var dialog = new dijit.Dialog();
• C.In the "Close" or "Cancel" button of each dialog add a call to validateForm in the onClick event.
• D.Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
  using the following code:
  /**
  *Custom Dojo Control
  */
  dojo.provide('com.myco.widget.Dialog');
  dojo.require('dijit.Dialog');
  (function(){
  dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
  onHide: validateForm
  })
  }());
  /**
  *Initialization code
  */
  var dialog = new com.myco.widget.Dialog();
• E.Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
  using the following code:
  /**
  *Custom Dojo Control
  */
  dojo.provide('com.myco.widget.Dialog');
  dojo.require('dijit.Dialog');
  (function(){
  dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
  onHide: validateForm
  })
  }());
  /**
  *Initialization code
  */
  var dialog = new com.myco.widget.Dialog();
• F.Whenever he initializes a new dijit.Dialog, add an onHide event like so:
  var dialog = new dijit.Dialog({
  onHide: validateForm
  }
  );
• G.Create a custom Dojo control and use that instead of the standard dijit.Dialog in the application
  using the following code:
  /**
  *Custom Dojo Control
  */
  dojo.provide('com.myco.widget.Dialog');
  dojo.require('dijit.Dialog');
  (function(){
  dojo.declare("com.myco.widget.Dialog", dijit.Dialog, {
  onHide: validateForm
  })
  }());
  /**
  *Initialization code
  */
  var dialog = new com.myco.widget.Dialog();

Tamsin is building an XPages application for use on mobile devices. She finds the font and row height on View Panel controls too small and difficult to navigate on a touch screen. Which View Panel property should she add her CSS class to?

John wishes to add a Java Class to his XPages application. How would he do this?

• A.Switch to the Java Perspective and create a new Java Source Folder within the application (using the Package Explorer), and create the Java Class within that folder
• B.Expand his application in the "Applications Navigator" and create a new Java Agent, place the necessary Java logic within the agent, and call the agent from within the XPage
• C.Switch to the Java Perspective, navigate to the "Local" Java Source Folder within the application (using the Package Explorer), and create the Java Class within that folder
• D.Expand his application in the "Applications Navigator" and create a new Java Script Library and place the necessary Java logic within that script library?

Marco has built an XPage that has increased in complexity over time and now contains several hundred lines of XSP markup, with many postback actions that conditionalize the display of the page. He feels that the page does not perform well and is looking to improve the responsiveness for the end-user. He is considering the following actions to improve performance. All of the following actions may improve performance EXCEPT which one:

• A.Use scoped variables to store/retrieve data that will not change between postback requests.
• B.Reduce the size of the page by splitting it up into several custom controls wherever possible.
• C.Use Partial Refresh to conditionally redraw only those parts of the page impacted by postback actions.
• D.Conditionally set the "loaded" property to "true" for controls and data sources that are displayed, and "false" when they are hidden.
