CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux administrator discovers that the account reports_user can open an interactive shell with ssh, even though the account should be limited to Secure File Transfer Protocol (SFTP) uploads on port 22. The change must apply only to that one account and must not affect other users who legitimately need full SSH access. Which single modification to /etc/ssh/sshd_config best meets the requirement?

A reboot is not an acceptable solution; the fix must take effect after the standard sshd service reload.

  • Append a Match block for reports_user that contains ForceCommand internal-sftp, then reload sshd.

  • Change reports_user's login shell in /etc/passwd to /sbin/nologin.

  • Add DenyUsers reports_user to sshd_config and restart the sshd service.

  • Replace the existing SFTP Subsystem line with Subsystem sftp internal-sftp.
