Which statement best describes a capability shared by both hardware and software firewalls?

• A. Blocking unauthorized traffic.
• B. They require cloud management.
• C. They replace antivirus software.
• D. Policy rules and monitoring can be configured.

Answer: (D)

Policy rules and monitoring are the core features that both hardware and software firewalls share. You can define exactly which traffic to allow or block (based on factors like IP addresses, ports, and protocols) and you can observe and log what passes through for security and troubleshooting. This ability to configure rules and actively monitor traffic applies to both types, making it the strongest, most universally shared capability. Blocking unauthorized traffic is a true function of firewalls, but describing the management and monitoring aspect captures a fundamental capability common to both forms. Cloud management isn’t universal—some firewalls operate without it— and they do not replace antivirus software, which is a separate security layer.
