What does Rob do with the second validation rule he creates?

The second validation rule that Rob creates is focused on evaluating the name of the object's validation rule. This indicates that the validation rule is designed to ensure that the naming conventions or specific naming criteria for the object are adhered to, which is critical for maintaining consistency and clarity in data management within the application.

Validation rules serve as a safeguard, enforcing certain standards and conditions that must be met before an object can be saved or deployed. By checking the name of the object's validation rule, Rob is ensuring that the naming conventions are followed, which can prevent errors later in the process.

Other choices encompass different aspects of validation rules, but focusing on the name helps maintain a clear structure in data integrity and compliance with organizational standards.
