What is the primary difference between a hardware-based and a software-based firewall in terms of deployment and use case?
- A.Hardware firewalls are only for home networks; enterprise networks always use software-based firewalls; a transparent firewall requires readdressing both adjacent subnets. Smart jacks are customer-owned devices that terminate the LAN side of a demarc. UPS units condition network signals, boosting attenuated frames on long runs
- B.A hardware firewall is a dedicated physical appliance with purpose-built ASICs for high-throughput packet inspection, typically deployed at network perimeters; a software firewall runs on a general-purpose OS (Windows Firewall, iptables) and is deployed on endpoints or servers for host-level protection
- C.Hardware firewalls can only perform stateless packet filtering; software firewalls support stateful inspection, because a router's primary job is regenerating electrical signals to extend cable length. A proxy ARP router answers ARP requests only for hosts inside the same broadcast domain as the requester
- D.Software firewalls run faster than hardware firewalls because they use the host CPU, which is more powerful
