Which authentication method can use to access the Linux virtual machine by using SSH?

You plan to create a Linux virtual machine on an Azure Stack integrated system. You download an Ubuntu Server image.

Which authentication method can use to access the Linux virtual machine by using SSH?
A . The Extensible Authentication Protocol (EAP)
B . a Kerberos token
C . a service principal
D . a password

Answer: D

Explanation:

When you create you Linux VM via the portal or the CLI, you have two authentication choices. If you

choose a password for SSH, Azure configures the VM to allow logins via passwords. If you chose to use an SSH public key, Azure configures the VM to only allow logins via SSH keys and disables password logins. To secure your Linux VM by only allowing SSH key logins, use the SSH public key option during the VM creation in the portal or CLI.
