Answer: A,B,D


NEW QUESTION # 140
Which code in a Visualforce page and/or controller might present a security vulnerability?

Answer: C

Explanation:
This code is vulnerable to a cross-site scripting (XSS) attack, because it takes user-supplied input and outputs it directly back to the user without escaping the XSS-vulnerable characters, such as <, >, ", ', and &. By setting the escape attribute to false, the developer disables the anti-XSS filter that is enabled by default for most Visualforce tags. An attacker can exploit this vulnerability by injecting malicious HTML or JavaScript code into the userInput parameter, which can then execute on the user's browser and compromise their security or privacy.

A developer has the following code block:
public class PaymentTax {public static decimal SalesTax = 0.0875;} trigger OpportunityLineItemTrigger on OpportunityLineItem (before insert, before update) {PaymentTax PayTax = new PaymentTax();decimal ProductTax = ProductCost * XXXXXXXXXXX;} To calculate the productTax, which code segment would a developer insert at the XXXXXXXXXXX to make the value the class variable SalesTax accessible within the trigger?

Answer: B


NEW QUESTION # 143
Which statement describes the execution order when trigger are associated to the same object and event?

Answer: D

Explanation:
When multiple triggers are associated to the same object and event, such as before insert, Salesforce does not guarantee the order of execution of those triggers. Therefore, it is best practice to avoid having multiple triggers for the same object and event, and instead consolidate the logic into a single trigger handler class. This way, you can control the order of execution of your trigger logic and avoid unexpected results or conflicts.
