Answer» RIGHT choice is (b) PACKET filter The explanation: As you know, firewalls are AVAILABLE as hardware appliances, as software-only, or a combination of the TWO. In every case, the purpose of a firewall is to ISOLATE your trusted internal network (or your personal PC) from the dangers of unknown resources on the Internet and other network connections that may be harmful. The firewall prevents unauthorized access to your internal, trusted network from outside threats.
