Architecture is similar to a dual-homed architecture except it uses more than two interfaces.

• A. Data Interface
• B. Dual-Home Firewall
• C. Auditing and Monitoring Services
• D. Multi-Homed Firewall

Answer: (D)

The concept being tested is how firewall architectures scale when there are multiple external connections. A dual-homed setup uses exactly two external interfaces to connect to different networks. When an architecture uses more than two interfaces, it’s described as a multi-homed firewall. This term emphasizes connectivity to multiple networks or Internet upstreams, providing greater redundancy and path diversity. The other options aren’t about the number of external connections: a data interface isn’t a standard architectural term for this idea, auditing and monitoring services refer to security functions rather than how many interfaces a firewall has, and a dual-homed firewall specifically implies two interfaces, not more.
