An administrator has been tasked with increasing security on a Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH.
What is the easiest way for the administrator to meet these needs?
Enabling Cluster Lockdown and providing an RSA key is the easiest way to increase security by disabling password authentication and moving to key-based SSH. This approach directly addresses the requirement of using key-based authentication and ensures that password-based access is disabled.
