Lydia wants to create a JSON string to represent an array with three objects. Each object has two variables, vA and vB, set to different string values of "one", "two", "three", "four", "five", and "six".
What is the proper syntax for the JSON string?

• A. "[ { vA: one, vB: two },{ vA: three, vB: four },{ vA: five, vB: six } ]"
• B. new Array(new Object({ vA: 'one', vB: 'two' }), new Object({ vA: 'one', vB: 'two' }), new Object({ vA: 'one', vB: 'two' }));
• C. "[ { vA: 'one', vB: 'two' },{ vA: 'three', vB: 'four' },{ vA: 'five', vB: 'six' } ]"
• D. [ { vA: 'one', vB: 'two' },{ vA: 'three', vB: 'four' },{ vA: 'five', vB: 'six' } ]

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

Pat wishes to create a new XPages UI control which will take user input. At a MINIMUM which of the following does he need to do?

• A. Create a UI Component extension Java Class that extends UIInputComponent, create an xspconfig file to define the tag, create a Java Class which will serve as a renderer, in order to render the tag as HTML markup.
• B. Create a UI Component extension Java Class that extends UIInput, create an xsp-config file to define the tag, create a Java Class which will serve as a renderer, in order to render the tag as HTML markup.
• C. Create a custom control with an edit box and reuse the custom control within the XPages
• D. Create a UI Component extension Java Class that extends UIInputComponent, create an xspconfig file to define the tag, create a Java Class which will serve as a renderer, in order to render the tag as HTML markup. Then create a managed bean definition in faces-config.xml.

Liz wants to make the user confirm their action when they try and delete a document from the application using a delete button. The confirmation message needs to display the title of the document in it. What is the best way to compute this message?

• A. In the server side event of the delete button use the following code:
  if (confirm("Are you sure you want to delete the document " +
  document1.getItemValueString('title'))){
  return true;
  }else{
  return false;
  }
• B. In the client side event of the delete button use the following code:
  if (confirm("Are you sure you want to delete the document " +
  "#{javascript:document1.getItemValueString('title')}")){
  return true;
  }else{
  return false;
  }
• C. In the server side event of the delete button use the following code:
  if (confirm("Are you sure you want to delete the document " +
  "#{javascript:document1.getItemValueString('title')}"){
  return true;
  }else{
  return false;
  }
• D. In the client side event of the delete button use the following code:
  if (confirm("Are you sure you want to delete the document " +
  document1.getItemValueString('title'))){
  return true;
  }else{
  return false;
  }
