What is the purpose of field-level validations?

• A. To automatically correct mistakes after submission.
• B. To prevent invalid data entry, ensure data consistency, and enforce business rules at point of entry.
• C. To speed up data entry by bypassing checks.
• D. To enable automated data export

Answer: (B)

Field-level validations are checks applied to each input as it’s entered, ensuring only valid data is accepted. They prevent invalid data from entering the system by enforcing rules at the moment of entry—required fields must be filled, values must match the expected type and format, ranges or enumerations must be respected, and business constraints must be followed. Validating data at this point keeps information consistent across records, supports reliable reporting, and reduces the need for corrections after submission. This approach is not about automatically correcting mistakes, bypassing checks to speed entry, or exporting data, but about catching and guiding fixes before the data is saved.
