NEW QUESTION # 114
A developer needs to implement a system audit feature that allows users, assigned to a custom profile named "Auditors", to perform searches against the historical records in the Account object. The developer must ensure the search is able to return history records that are between 6 and 12 months old.
Given the code below, which select statement should be inserted below as a valid way to retrieve the Account History records ranging from 6 to 12 months old?
A)
B)
C) D)
Answer: B
Explanation:
Given the code snippet, the correct query to retrieve Account History records between 6 and 12 months old would be the one that includes a WHERE clause filtering records where the CreatedDate is greater than or equal to initialDate and less than or equal to endDate. Option B's statement does this correctly by using the >= and <= operators to define the range between initialDate (which is set to today's date minus 12 months) and endDate (set to today's date minus 6 months). Options A, C, and D either use incorrect comparison operators or compare against the wrong variables, resulting in an incorrect data set being returned.

NEW QUESTION # 115
An Apex trigger creates an order co record every time an Opportunity is won by a Sales Rep. Recently the trigger is creating two orders.
What is the optimal technique for 2 developer to troubleshoot this?
Answer: D
Explanation:
To troubleshoot the issue of a trigger creating two order records, adding System.debug() statements in the trigger and analyzing the log output in the Developer Console is an effective technique. This will help identify if the trigger is being called more than once or if there is another automation (such as a flow or workflow) causing the additional record creation.
NEW QUESTION # 116

How should a developer change the component to be responsive for mobile and tablet devices? A)
B)
C)
D)
Answer: D
Explanation:
To make the Aura component responsive, the developer should set multipleRows="true" to allow the layout items to wrap onto multiple rows on smaller devices. Additionally, setting the size attribute for different device sizes ensures that the layout adapts to the screen width.
NEW QUESTION # 117
A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.
When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry, What is the optimal way to implement this?
Answer: D
Explanation:
The <apex:actionSupport> component is designed to be used with another component to provide AJAX support. When the value of the industry select list changes, the <apex:actionSupport> can trigger an AJAX request to the server, causing the page to rerender the table of Accounts with the matching industry. This process occurs without a full page refresh, providing a smoother user experience.
