A Multi-homed Firewall is configured with multiple network interfaces. Which description best fits it?

• A. One interface
• B. Two interfaces
• C. More than three interfaces
• D. Four interfaces

Answer: (C)

A multi-homed firewall uses multiple network interfaces to connect to several networks, allowing traffic to be segregated and paths to be redundant. In real deployments, this setup often includes connections to external networks, an internal network, a DMZ, and sometimes a management or backup path. That kind of arrangement typically requires several interfaces, often more than three, to maintain clear boundaries between segments and provide resilience against link failures. Therefore, describing it as having more than three interfaces best aligns with how many environments implement multi-homing, where multiple distinct network connections are the norm to support isolation and fault tolerance.
