What is a standalone hardware device that performs only firewall functions and is embedded in the appliance's firmware?

• A. Router firewall
• B. Appliance firewall
• C. State table
• D. Packet filtering firewall

Answer: (B)

A firewall appliance is a dedicated hardware device whose sole purpose is firewalling, with its firewall software tightly embedded in the device’s firmware. This means the hardware and firmware are purpose-built to enforce security rules, provide predictable performance, and simplify management, without being bogged down by other non-firewall functions. That focus on dedicated firewall duties is what makes it the best fit for the description. Other options don’t match this concept. A router with firewall capabilities is a general-purpose device that includes firewall features but isn’t dedicated solely to firewalling. A state table is merely the data structure a firewall uses to track active connections, not a physical device. A packet filtering firewall describes a method of filtering traffic, which can be implemented in software or hardware, but by itself does not specify a standalone hardware device embedded in firmware.
