Question 1
A Visualforce page loads slowly due to the large amount of data it displays.
Which strategy can a developer use to improve the performance?
- Use Javascript to move data processing to the browser instead of the controller.
- Use the transient keywords for the List variables used in the custom controller.
- Use lazy loading to load the data on demand, instead of the controller’s constructor.
- Use an <apex:actionPoller> in the page to load all of the data asynchronously.

A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.
<apex:selectList value="{!selectedIndustry}">

When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry.
What is the optimal way to implement this?
