There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user.
The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, "Maximum view state size limit exceeded".
What step should the developer take to resolve this issue?
Answer: A
Explanation:
To resolve the issue of the Visualforce page taking too long to display results or exceeding the view state limit, the developer should use a StandardSetController or implement SOQL LIMIT in the Apex controller.
This limits the number of records that are processed and displayed at one time, which can prevent view state errors and improve performance.
