Question

Which device permits or denies network traffic based on a set of rules?

Options

• Afirewall
• Bswitch
• Caccess point
• Dwireless controller

Explanation

A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on predefined security rules.

Common mistakes.

• B. A switch operates at Layer 2 (data link layer) and forwards traffic based on MAC addresses within a local network segment, without inspecting or filtering based on higher-layer rules.
• C. An access point connects wireless devices to a wired network and primarily handles wireless connectivity and Layer 2 forwarding, not policy-based traffic filtering.
• D. A wireless controller centrally manages access points and their configurations, but it does not directly perform packet filtering based on security rules like a firewall.
