CompTIA Linux+ (XK0-005) — Question 43

Which of the following enables administrators to configure and enforce MFA on a Linux system?

Answer options

• A. Kerberos
• B. SELinux
• C. PAM
• D. PKI

Correct answer: C

Explanation

The correct answer is C, PAM (Pluggable Authentication Modules), which provides a way to integrate multiple authentication methods, including MFA, into Linux systems. A (Kerberos) is primarily for network authentication, B (SELinux) focuses on security policies and access control, and D (PKI) is related to managing digital certificates, which does not directly enforce MFA.
