Salesforce Platform Developer I (legacy) — Question 3

A platform developer at Universal Containers needs to create a custom button for the Account object that, when clicked, will perform a series of calculations and redirect the user to a custom Visualforce page.
Which three attributes need to be defined with values in the <apex:page> tag to accomplish this? (Choose three.)

Answer options

• A. action
• B. renderAs
• C. standardController
• D. readOnly
• E. extensions

Correct answer: A, C, E

Explanation

The 'action' attribute is essential for defining what happens when the page is loaded, while 'standardController' specifies the controller for the page, enabling it to interact with the Account object. 'extensions' allows for additional controller logic, which is necessary for complex calculations, while 'renderAs' and 'readOnly' are not required for this functionality.
