CompTIA Linux+ XK0-006 (V8) Practice Question

A system administrator needs to modify sudo privileges for a user. Instead of using the recommended visudo command, they open /etc/sudoers directly with a standard text editor like nano or vi. They accidentally introduce a syntax error before saving and exiting the file. What is the most likely and immediate consequence of this action?

  • Only the user account being modified in the file will be unable to use sudo.

  • The system will ignore the line with the syntax error and apply all other valid rules.

  • The sudo command will become unusable for all users due to the parse error.

  • The system will automatically revert to the last known-good version of the sudoers file.
