Salesforce Certified Platform Developer II — Question 258

Which three Visualforce components can be used to initiate Ajax behavior to perform partial page updates? (Choose three.)

Answer options

• A. <apex:actionSupport>
• B. <apex:commandLink>
• C. <apex:actionStatus>
• D. <apex:commandButton>
• E. <apex:form>

Correct answer: A, B, D

Explanation

<apex:actionSupport>, <apex:commandLink>, and <apex:commandButton> are designed to facilitate Ajax functionality in Visualforce, allowing for partial page updates. In contrast, <apex:actionStatus> is used to display the status of an Ajax request but does not initiate one, and <apex:form> serves as a container for form elements but does not directly enable Ajax behavior.
