CompTIA Linux+ (XK0-004) — Question 317

A security administrator must use a password and a token to log in to the server.
Which of the following processes does this describe?

Answer options

• A. Kerberos authentication
• B. RADIUS authentication
• C. Biometric authentication
• D. Multifactor authentication
• E. LDAP authentication

Correct answer: D

Explanation

The correct answer is D, Multifactor authentication, as it requires multiple forms of verification, such as a password and a token. The other options do not involve the combination of two distinct authentication factors; for example, Kerberos and RADIUS are single-factor methods, while biometric authentication relies solely on physical traits.
