Refer to Exhibit. An administrator sees the alert shown in the exhibit. What should the administrator do to ensure the nutanix user can no longer SSH to a CVM using a password?
The correct answer is C. Enable Cluster Lockdown. Cluster Lockdown is the Nutanix security feature that disables password-based SSH authentication on CVMs and requires key-based authentication instead. When enabled, it prevents any user-including the built-in 'nutanix' user-from logging into a CVM via SSH using a password…

Explanation
Cluster Lockdown is the Nutanix security feature that disables password-based SSH authentication on CVMs and requires key-based authentication instead. When enabled, it prevents any user-including the built-in 'nutanix' user-from logging into a CVM via SSH using a password. Renaming or deleting the nutanix user (A, D) would break internal cluster operations that depend on that account. Blocking port 22 entirely (B) would also prevent legitimate key-based SSH access needed for administration. Cluster Lockdown is the purpose-built, least-disruptive solution for this security requirement.
