Exam XK0-005 topic 1 question 163 discussion

C is correct, but so is A. Kerberos uses the ticket granting ticket system often used for federated trust relationships. For each resources requiring additional verification, a Kerberos system can require additional information such as a token or a verification code sent to a known phone number. Since this is a Linux exam, PAM will suffice.

The technology that enables administrators to configure and enforce Multi-Factor Authentication (MFA) on a Linux system is: C. PAM (Pluggable Authentication Modules) Explanation: PAM (Pluggable Authentication Modules) is a framework that allows the integration of multiple authentication schemes for Linux systems. It provides a way for administrators to configure and enforce MFA for user authentication by enabling the use of multiple factors, such as passwords, smart cards, biometrics, and others. PAM allows the configuration of authentication policies for different services and applications running on a Linux system. This makes it possible to implement MFA for specific applications or services, rather than applying it to the entire system. Additionally, PAM allows administrators to configure different authentication methods for different users or user groups, depending on their access requirements.

C. PAM (Pluggable Authentication Modules) enables administrators to configure and enforce multi-factor authentication (MFA) on a Linux system. PAM is a modular architecture that allows system administrators to specify how authentication should be performed on their systems, including the use of MFA. This can be achieved by adding additional modules to the PAM configuration, such as modules for OTPs, smart cards, or biometric authentication. PAM can also be used to integrate with external authentication systems, such as LDAP, Kerberos, or RADIUS, to enforce MFA for authentication to various services on the Linux system.

Choosing C here.

C is correct. Pluggable Authentication Modules allow Linux to work with Google Authenticator and other OTP tools to add two-factor security to your system. https://www.redhat.com/sysadmin/mfa-linux

Pluggable Authentication Modules (PAM) provide for multi-factor authentication on Linux. Answer C.
