A reviewer must enter a reason in the comments field when a candidate is recommended for hire. How can this be enforced?

1. Create a required comments field.

2. Create a formula field.

3. Create a validation rule.

4. Create a required Visualforce component.

The correct answer is: Create a validation rule.

The correct answer is to create a validation rule to ensure that a reason is entered in the comments field when a candidate is recommended for hire. Validation rules are specifically designed to enforce data integrity and business rules in Salesforce. By creating a validation rule, you can define a logical condition that must be met for the record to be saved. In this case, the validation rule can check if the "comments" field is populated when the field that indicates a recommendation for hire is set to true. If the comments field is empty, the rule will prevent the record from being saved and prompt the user to enter a reason. This solution allows for more flexibility and customization, as the validation rule can handle specific conditions and provide meaningful error messages to guide users on what is required. It effectively enforces the requirement without altering the fundamental nature of the comments field itself, ensuring that all candidates who are recommended for hire have a documented reason in their review comments.
