Answer 1

RADIUS authentication is not a way to log into the Palo Alto firewalls at the GW/C2.

Step-by-step explanation:

The correct answer is RADIUS authentication. RADIUS stands for Remote Authentication Dial-In User Service and it is an authentication protocol that allows users to be authenticated by a central server. It is commonly used for authenticating remote access users, such as those connecting through a VPN. Palo Alto firewalls support a variety of authentication methods, including username and password, SSH key authentication, and TACACS+ authentication.
