A developer needs to check the state of one of the JSF Managed Beans when an application is paused. Although all Managed Beans (and other scoped objects) can be found by looking at the FacesContext object available in the Variables view, finding the objects this way can be difficult and time consuming.

• A.  enable the runtime JVMPI values for the variables
• B.  print the report of the scoped objects and view attributes, then filter the scoped object out of the list
• C.  create matches for scoped objects and view attributes and view the values at the Expression window

An existing Web 2.0 application has several Ajax functions and an effective interface. It calls server side logic using XMLHttpRequest to pass and receive XML messages. When would using JSON messages on all Web 2.0 applications dramatically improve the performance of the application?

• A.  when the application uses a web service call using JSON between the web page and backend, then the web service will be able to use Web Service Security
• B.  when the application servlets are able to process the requests more efficiently and better integrate with the backend systems
• C.  when the browser's HTML renderer is able to display the results much clearer when information is conveyed using JSON
• D.  when the existing Ajax functions pass large XML messages, and using JSON will reduce the size of the messages
