Which term connects multiple network segments and can forward traffic between them?

• A. DNS
• B. ISP
• C. Ethernet Switch
• D. Server

Answer: (C)

Connecting multiple network segments and forwarding traffic between them is what an Ethernet switch does in a local area network. It sits at the center of the LAN, learns where devices live by examining MAC addresses, and forwards frames only to the appropriate port, effectively linking different parts of the network. This role is distinct from DNS, which translates names to IP addresses; from an ISP, which provides external Internet access; and from a server, which offers services but doesn’t route traffic between LAN segments. If routing between different networks is needed, a router or a Layer 3 switch handles that, but the device that directly connects and forwards traffic among network segments in a LAN is the Ethernet switch.
