Question 1

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.

All of the following actions may improve performance EXCEPT which one:

A. Conditionally set the "loaded" property to "true" for controls and data sources that are displayed, and "false" when they are hidden.

B. Reduce the size of the page by splitting it up into several custom controls wherever possible.

C. Use scoped variables to store/retrieve data that will not change between postback requests.

D. Use Partial Refresh to conditionally redraw only those parts of the page impacted by postback actions.
