Which configuration should the administrator use to disable password authentication over SSH?
To disable password authentication over SSH, the administrator needs to modify the SSH configuration on each host. This typically involves editing the SSH daemon configuration file (usually found at /etc/ssh/sshd_config) and setting 'PasswordAuthentication' to 'no'. This change needs to be applied to each host to ensure that password-based SSH access is disabled cluster-wide. Other options like enabling cluster lockdown in Prism or configuring a proxy server do not directly address the SSH configuration settings required to disable password authentication.

Checked in production. Prism Element, Settings, Cluster Lockdown, quote... "Cluster Lockdown disables the ability to login to the cluster via SSH password-challenge."
