A systems administrator needs to prevent the root account from being used to log in to a Linux server via SSH. Which of the following configuration ies does the systems administrator need to edit to p

/etc/passwd stores local user account metadata such as usernames, UIDs, GIDs, and home directories, but does not contain any SSH access controls.

The SSH daemon configuration file (standardly located at /etc/ssh/sshd_config) contains the PermitRootLogin directive that governs root access over SSH. Setting 'PermitRootLogin no' in this file and restarting the sshd service effectively blocks root from authenticating via SSH, which is a critical security hardening step.

~/.ssh/config is the per-user SSH client configuration file that controls outbound SSH connections initiated by that user, not server-side authentication policy.

/etc/ayaconfig/sshd is not a valid or standard path on Linux systems - SSH daemon configuration is not stored in this location.
