A. B. C. D.B.
Multifactor authentication (MFA) is a security mechanism that requires users to provide two or more authentication factors to gain access to a system or application. This is done to enhance security by adding an extra layer of protection, making it more difficult for unauthorized users to gain access to sensitive information.
Out of the options provided, the only one that meets the requirements for multifactor authentication is option C - Smart card and hardware token.
A. Username, PIN, and employee ID number: This option only includes two factors of authentication, something the user knows (username and PIN). While an employee ID number could be considered a third factor, it is not a recommended one as it is easily guessable or could be obtained through social engineering techniques.
B. Fingerprint and password: This option includes two factors, something the user knows (password) and something the user is (fingerprint). While this provides some level of security, it is not considered true multifactor authentication as both factors are part of the same category (biometric).
D. Voice recognition and retina scan: This option includes two factors, something the user is (voice and retina), but is not practical for most situations due to cost and complexity.
C. Smart card and hardware token: This option includes two separate factors, something the user has (smart card) and something the user possesses (hardware token). This combination is an example of true multifactor authentication and is widely used in high-security environments.
In conclusion, option C - Smart card and hardware token is the only one that meets the requirements for multifactor authentication.
