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?

Options:

Use an Approval Process to enforce the completion of a valid email address using an outbound message action,

Submit a REST API Callout with a JSON payload and validate the fields on a third party system

Use a custom Lightning Web component to make a callout to validate the fields on a third party system.

Use a before-save Apex trigger on the Lead object to validate the email address and display an error message if it is invalid

Answer:

Explanation:

To add an additional layer of validation for email addresses on Lead records by using automation and possibly an external validation service, the best solution is to use a custom Lightning Web Component (LWC).

Option C: Use a custom Lightning Web Component to make a callout to validate the fields on a third-party system

Real-Time Validation: An LWC can perform client-side validation and make callouts to external systems to validate the email address as the user inputs data.

User Experience: Provides immediate feedback to the user, improving data quality at the point of entry.

Limitations: This solution works when data is entered through the UI using the LWC component.

[:, Lightning Web Components, Making Callouts from Lightning Components, Why Other Options are Less Optimal or Incorrect:, Option A: Use an Approval Process to enforce the completion of a valid email address using an outbound message action, Not Suitable: Approval Processes are not intended for data validation., Outbound Messages: Used to send data to external systems but do not enforce validation during record creation., Reference: Approval Processes, Option B: Submit a REST API Callout with a JSON payload and validate the fields on a third-party system, Vague Implementation: Does not specify where or how the callout is made., Technical Constraints: Making synchronous callouts during record save (e.g., from a trigger) is not permitted., Reference: Apex Callouts and Triggers, Option D: Use a before-save Apex trigger on the Lead object to validate the email address and display an error message if it is invalid, Callout Limitations: Apex triggers cannot make callouts in a before-save context., Asynchronous Callouts: Using asynchronous methods (e.g., @future) cannot prevent the record from being saved., Reference:, Apex Triggers and Callouts, Future Methods, Conclusion:, Using a custom Lightning Web Component is the best solution to add an additional layer of validation during data entry., It allows for real-time validation via callouts to a third-party system., While it doesn't cover records created via other means (API, data import), the existing validation rule would still enforce that an email address is provided., ]

Questions 40

A developer created a new after insert trigger on the Lead object that creates Task records for each Lead.

After deploying to production, an existing outside integration that inserts Lead records in batches to Salesforce is occasionally reporting total batch failures being caused by the Task insert statement. This causes the integration process in the outside system to stop, requiring a manual restart.

Which change should the developer make to allow the integration to continue when some records in a batch cause failure due to the Task insert statement, so that manual restarts are not needed?
