NEW QUESTION # 127
A developer created an Opportunity trigger that updates the account rating when an associated opportunity is considered high value. Current criteria for an opportunity to be considered high value is an amount greater than or equal to $1,000,000. However, this criteria value can change over time.
There is a new requirement to also display high value opportunities in a Lightning web component.
Which two actions should the developer take to meet these business requirements, and also prevent the business logic that obtains the high value opportunities from being repeated in more than one place?
Choose 2 answers
Answer: A,B
Explanation:
Creating a helper class allows the logic to be centralized and reused in both the trigger and the Lightning Web Component (LWC), avoiding repetition. Using custom metadata to store the criteria value allows easy updates without code changes and can be referenced from both the helper class and the trigger.

NEW QUESTION # 128
A company's support process dictates that any time a case is closed with a status of "Could net fix," an Engineering Review custom object record should be created and populated with information from the case, the contact, and any of the products associated with the case.
What Is the correct way to automate this using an Apex trigger?
Answer: D
Explanation:
In Salesforce, triggers can be defined to execute before or after a DML operation. An "after" trigger is used when you want to use the records that have been changed and rely on their committed values. In this scenario, you would use an after update trigger because you need to create a new record (Engineering Review) after the case has been updated with a status of "Could not fix". This cannot be done in a "before" trigger because the changes have not yet been committed to the database.
Therefore, the correct answer is A, which specifies an after update trigger on the Case object to create and insert the Engineering Review record.
