LPIC-2 Exam 202 (Linux Engineer) — Question 119

Select the alternative that shows the correct way to disable a user login for all users except root.

Answer options

• A. The use of the pam_block module along with the /etc/login configuration file.
• B. The use of the pam_deny module along with the /etc/deny configuration file.
• C. The use of the pam_pwdb module along with the /etc/pwdv.conf configuration file.
• D. The use of the pam_nologin module along with the /etc/nologin configuration file.

Correct answer: D

Explanation

The correct answer is D because the pam_nologin module restricts user logins while allowing root access when the /etc/nologin file is present. Options A, B, and C are incorrect as they do not serve the purpose of disabling user logins while allowing root access in the specified manner.
