Data Validation Rules Enforcement | Salesforce ADX-201 Exam

D.

Data validation rules in Salesforce are used to ensure that data entered into records meets certain criteria. These rules can be defined at the field level or at the object level, and they are enforced automatically by the system. The answer to the question is D, data validation rules are enforced upon saving a record.

When a user creates or updates a record in Salesforce, the system first performs a series of checks to ensure that the data is valid. This includes checking any validation rules that have been defined for the object or fields being edited. The validation rules are checked at the time of saving the record, not during any other action such as opening, closing, or editing the record.

For example, if a validation rule requires that the value entered in a certain field is unique across all records of that object, Salesforce will check all existing records and verify that no other record has the same value in that field. If another record exists with the same value, Salesforce will prevent the user from saving the new record until the value in the field is changed to a unique value.

In conclusion, data validation rules are enforced upon saving a record in Salesforce. This ensures that any data entered or edited in the system meets the criteria defined by the organization, reducing errors and maintaining data integrity.
