Which of the following describes a component of the I2N?

• A. Ethernet router
• B. Battery
• C. Antenna
• D. CPU

Answer: (A)

A network device that routes traffic between networks is a fundamental networking component. The Ethernet router fits this role because it connects different networks and directs data packets toward their destinations, enabling communication across subnets and networks. It operates by examining IP addresses and choosing the best path for forwarding traffic, which is the core function of inter-network connectivity. The other options don’t perform that inter-network routing role on their own: a battery provides power, not data flow; an antenna is a hardware element for wireless signaling but isn’t by itself a routing device; a CPU is just a processing unit inside devices, and while routers contain CPUs, the item described here is the networking device that enables routing between networks.
