NEW QUESTION # 187
A developer is writing code that requires making callouts to an external web service.
Which scenario necessitates that the callout be made in an asynchronous method?
Answer: A
Explanation:
Callouts cannot be made from a synchronous context such as an Apex trigger because they might exceed the maximum execution time, leading to timeouts. Asynchronous methods, such as future or Queueable, are required to handle callouts from triggers.
NEW QUESTION # 188
A company wants to incorporate a third-party weh service to set the Address fields when an Account is inserted, if they have not already been set.
What is the optimal way to achieve this?
Answer: D
Explanation:
To make a callout to set the Address fields when an Account is inserted without violating the Salesforce limit against callouts from triggers, a developer can use a trigger to execute a Queueable job. The Queueable job can then safely make the callout.
NEW QUESTION # 189
Which use case can be performed only by using asynchronous Apex?
Answer: B
Explanation:
Making a callout from an Apex trigger is not allowed synchronously; hence, such callouts must be performed in an asynchronous context. The only way to perform this within the Salesforce platform is by using asynchronous Apex, such as @future methods or Queueable Apex.
NEW QUESTION # 190
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: C
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.

NEW QUESTION # 191
A software company uses a custom object, Defact__c, to track defects in their software. Defect__c has organization-wide defaults set to private. Each Defect_ c has a related list of Reviewer < records, each with a lookup field to User that is used to indicate that the User will review the defect__c.
What should be used to give the User on the Reviewer_c record read only access to the Defect__c record on the Reviewer_c record?
Answer: B
Explanation:
Apex managed sharing is used to programmatically share records when organization-wide defaults are private. It allows for creating share records that give read-only access to users specified in a related list.
