NEW QUESTION # 141
As part of point-to-point integration, a developer must call an external web service which, due to high demand, takes a long time to provide a response. As part of the request, the developer must collect key Inputs from the end user before making the callout. Which two elements should the developer use to Implement these business requirements?
Choose 2 answers
Answer: A,C
Explanation:
For implementing business requirements that involve collecting key inputs from the end user before making a long-running callout, a combination of a Lightning web component and an Apex method that returns a Continuation object is ideal. The Lightning web component can be used to build a user-friendly interface to collect the inputs, and the Continuation object in Apex allows for managing the callout in an asynchronous way. This pattern prevents the user interface from freezing and provides a better user experience by allowing the callout to run in the background.

NEW QUESTION # 142
When developing a Lightning web component, which setting displays lightninglayout-items im one column on small devices, such as mobile phones, and in two columns on tablet-size and desktop-size screens?
Answer: B
Explanation:
To display lightning-layout-items in one column on small devices and in two columns on larger devices, you should set the size attribute to "12" for small devices and the medium-device-size attribute to "6". This ensures that on small devices each item takes the full width, and on medium or larger devices, items take up half the width.
NEW QUESTION # 143
An org has an existing process, built using Process Builder, on Opportunity that sets a custom field, CommissionBaseAmount__c, when an Opportunity is edited and the Opportunity's Amount changes.
A developer recently deployed an Opportunity before update trigger that uses the CommissionBaseAmount__c and complex logic to calculate a value for a custom field, CommissionAmount__c, when an Opportunity stage changes to Closed/Won.
Users report that when they change the Opportunity to Closed/Won and also change the Amount during the same save, the CommissionAmount__c is incorrect.
Which action should the developer take to correct this problem?
Answer: B
Explanation:
The issue described is likely due to the order of execution in Salesforce, where processes in Process Builder run after all before triggers. If the Opportunity's Amount is changed and the CommissionBaseAmount__c is set by Process Builder, the trigger that calculates CommissionAmount__c may not see the updated value if it operates before the process.
Replacing the process with a before-save record-triggered flow (formerly known as Fast Field Update) would ensure that CommissionBaseAmount__c is updated before the trigger runs. In a before-save flow, field updates occur before any Apex before update triggers fire, which means the trigger would have the updated value of CommissionBaseAmount__c to use in its calculation.
