NEW QUESTION # 45
Universal Containers wants to ensure that all new leads created in the system have a valid email address. They have already created a validation rule to enforce this requirement, but want to add an additional layer of validation using automation.
What would be the best solution for this requirement?

A. Use a custom Lightning Web component to make a callout to validate the fields on a third party system.
B. Use a before-save Apex trigger on the Lead object to validate the email address and display an error message if it is invalid
C. Submit a REST API Callout with a JSON payload and validate the fields on a third party system
D. Use an Approval Process to enforce the completion of a valid email address using an outbound message action.

Answer: B

Explanation:
Before-save Apex Trigger:
This is the best solution because abefore-save triggerruns before the record is saved to the database, providing an opportunity to validate or modify the data.
In this case, the Apex trigger can validate the email address using a regular expression or a third-party API call to ensure the email address is valid. If the email is invalid, an error message can be displayed using addError().
Why not the other options?
A: Submit a REST API Callout with a JSON payload:
REST callouts are more complex and generally not recommended for simple validation tasks like email format validation. Additionally, callouts cannot be performed directly in a before-save trigger.
C: Use a custom Lightning Web Component (LWC):
LWCs are primarily for UI interactions and should not be used to enforce data validations that are server-side requirements.
D: Use an Approval Process:
Approval Processes are for managing the approval flow of records, not for real-time validations. They cannot enforce email validation directly.
