Why each option
Junos OS supports RADIUS and TACACS+ as primary external authentication methods for centralized user management.
RADIUS is a standard external authentication protocol widely supported by Junos OS for authenticating users against a central server.
While Kerberos is an authentication protocol, it is not primarily used by Junos OS as a direct external authentication method for device login by default like RADIUS or TACACS+.
IPsec is a suite of protocols for securing IP communications, providing authentication and encryption for data in transit, but it is not an external user authentication method for device login.
TACACS+ is another robust external authentication protocol, often used in enterprise environments, and fully supported by Junos OS.
