NEW QUESTION # 95
Refer to the exhibit
Users of this Visualforce page complain that the page does a full refresh every time the Search button Is pressed.
What should the developer do to ensure that a partial refresh Is made so that only the section identified with opportunity List is re-drawn on the screen?
Answer: B
Explanation:
To ensure that only a part of the Visualforce page is refreshed, developers can use the reRender attribute of the <apex:commandButton> tag. This attribute specifies the IDs of the components that should be re-rendered as a result of the action method being completed. In this case, setting the reRender attribute to the ID of the <apex:pageBlockSection> that contains the opportunity list will cause only that section to be updated on the page, resulting in a partial page refresh.
The correct answer is B because it uses the reRender attribute correctly to update only the specific part of the page (opportunityList) without a full page refresh.

NEW QUESTION # 97
A Visualforce page needs to make a callout to get billing information and tax information from two different REST endpoints. The information needs to be displayed to the user at the same time and the return value of the billing information contains the input for the tax information callout. Each endpoint might take up to two minutes to process.
How should a developer implement the callouts?
Answer: B
Explanation:
Using Continuation for both callouts is the optimal solution when you have long-running callouts in a Visualforce page, as it allows the page to wait for a long-running process without tying up server resources.
The Continuation pattern is specifically designed for scenarios where the request-response cycle could exceed the timeout limits.References: Visualforce Developer Guide - Continuations
