Which of the following technologies can be used as a central repository of Linux users and groups?
Correct Answer: A. LDAP
LDAP (Lightweight Directory Access Protocol) is widely used as a central repository for Linux users and groups. It stores user credentials and group information in a centralized directory, enabling consistent authentication and authorization across multiple Linux systems. LDAP simplifies user management, reduces administrative overhead, and enhances security by providing a single source of truth for user and group data.
Why other options are incorrect:
B. MFA
Multi-Factor Authentication (MFA) enhances security by requiring multiple verification methods but does not serve as a repository for user or group information. It complements authentication but does not manage user or group data centrally.
C. SSO
Single Sign-On (SSO) allows users to authenticate once to access multiple systems but relies on underlying directories like LDAP for user data. SSO is an authentication convenience, not a user/group repository.
D. PAM
Pluggable Authentication Modules (PAM) provide a framework for authentication on Linux systems but do not store user or group information. PAM works with backends like LDAP to authenticate users but is not a directory service itself.
