Which of the following is TRUE regarding routers and switches?

• A. Routers have more interfaces than switches.
• B. Routers have fewer interfaces than switches.
• C. Routers and switches have the same number of interfaces.
• D. Routers are not used for network traffic.

Answer: (B)

Routers typically have fewer interfaces than switches. This is because routers are designed to connect different networks and often have only a few interfaces to serve this purpose, such as WAN (Wide Area Network) and LAN (Local Area Network) interfaces. In contrast, switches are used to connect devices within the same network and generally have many more interfaces (ports) available to connect multiple devices, such as computers, printers, and servers. Routers operate at Layer 3 (the Network layer) of the OSI model, making routing decisions based on IP addresses, while switches primarily operate at Layer 2 (the Data Link layer) using MAC addresses to forward frames to the appropriate devices within the same network. This fundamental difference in function also contributes to the variation in the number of interfaces, with switches being designed to handle a larger number of connections directly. The other options do not accurately reflect the nature of routers and switches and their design purposes in network architecture.
