Question 3

Aaron has created an XPages application that has a couple of XPages to surface the same data to two different application roles in two completely different user interfaces. Each role can manipulate parts of the data, but in both cases, the data must adhere to the same business logic and rules. What would be the best way for Aaron to implement the same business logic in each XPage?

A. Create a common Server-Side JavaScript Library for the XPages to share that the user interface can use to execute the business logic B. Use a series of Custom Controls to hold the business logic and share them amongst the XPages C. Create a common Client-Side JavaScript Library for the XPages to share that the user interface can use to execute the business logic D. The user interface and the business logic in an XPage can not easily be separated and must be maintained in each XPage

Question 5

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

Question 6

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 perform as expected. B. The application will generate an error because you can not declare global Server-Side JavaScript variables C. 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. D. 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.
