Question : Which of the following data entry controls provides the GREATEST assurance that data entered does not contain errors ?
The Correct Answer is : A. Key verification Explanation : Key verification or one-to-one verification will yield the highest degree of confidence that data entered is error free. However, this could be impractical for large amounts of data. Segregation of data entry functions from data entry verification is an additional data entry control. Maintaining a log/record detailing the time, date, employee's initials/user-ID and progress of various data preparation and verification tasks, provides an audit trail. A check digit is added to data to ensure that original data have not been altered. If a check digit is wrongly keyed, this would lead to accepting incorrect data. A one-to-one verification could detect this category error also, by providing the highest degree of assurance.
