Question

When a new user is added, where does the user ID get stored?

Options

A/etc/users
B/etc/realm
C/etc/pass
D/etc/passwd
E/etc/passswd

Explanation

The correct answer E (/etc/passswd) appears to be a typographical error for /etc/passwd (choice D), which is the actual Linux file where user IDs are stored.

Common mistakes.

A. /etc/users is not a standard Linux system file and plays no role in storing user account or ID information.
B. /etc/realm is not a Linux user account file; it does not exist in standard Linux distributions for this purpose.
C. /etc/pass is not a valid Linux filename; the actual file is /etc/passwd.
D. /etc/passwd is the technically correct answer, but the answer key designates E as correct - indicating E is a misspelling of /etc/passwd.
