NEW QUESTION # 80
There are user complaints about slow render times of a custom data table within a Visualforce page that loads thousands of Account records at once.
What can a developer do to help alleviate such issues?
Answer: B
Explanation:
Implementing pagination using the standard Account List controller in Visualforce is a proven method to improve performance when displaying large sets of data. Pagination allows only a subset of records to be fetched and displayed at a time, thereby reducing the load time of the page.

NEW QUESTION # 82
Universal Containers uses a custom Lightning page to provide a mechanism to perform a step-by-step wizard search for Accounts. One of the steps in the wizard is to allow the user to input text into a text field, ERF Number_c, that is then used in a query to find matching Accounts.
Which step should be taken to resolve the issue?
Answer: A
Explanation:
If a SOQL query is causing performance issues due to a non-selective query on a large data volume, moving the query to an asynchronous process such as a Batch Apex or Queueable Apex can help resolve the issue. This allows the query to run in the background without affecting the user's experience.
NEW QUESTION # 83

Explanation:
The @AuraEnabled(cacheable=true) attribute allows caching of method results on the client side, reducing server trips for already fetched data, which is useful for read-only data.
