An administrator received a new shipment of mobile devices. Per company policy, all enterprise-issued devices must have two authentication methods, and the organization has already enforced the use of PIN codes as one method. Which of the following device features should the administrator enable?
Correct Answer: B
For securing mobile devices with two authentication methods, combining something the user knows (a PIN) with something the user is (biometrics) enhances security by implementing multi-factor authentication. * Smart card: Generally requires additional hardware and is not commonly used in mobile devices. * Biometrics: Uses unique biological traits such as fingerprints or facial recognition, providing a convenient and secure second method of authentication. * Hard token: Involves additional physical devices which might not be practical for mobile devices. * One-time password: Usually used for specific applications rather than as a general device authentication method.
