A multi-homed firewall is characterized by having how many interfaces?

• A. A device with a single interface
• B. A device with two interfaces
• C. A device with more than three interfaces
• D. A device with no interfaces

Answer: (C)

A multi-homed firewall is defined by its multiple network connections to separate networks, providing segmentation, routing choices, and redundancy. The idea is that the firewall isn’t limited to a single path but sits between several network segments, using multiple interfaces to manage traffic and failover. The best match here states the device has more than three interfaces, which explicitly communicates multiple network connections, aligning with the notion of multi-homed that supports several paths and networks. A single-interface device cannot be multi-homed, and a device with no interfaces can’t connect to networks. While two interfaces can be considered multi-homed in many contexts, this option indicates a higher degree of multiple connections, consistent with the concept in this question.
