What is an example of a network device that associates a network address with a port?
A. Switch
B. Router
C. Hub
D. DSL modem
Correct Answer: B
Explanation/Reference:
A router is a Layer 3 gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model.
Incorrect:
not switch: Any switch that provides this ‘basic’ functionality, operates at the 2nd OSI layer also known as the Datalink Layer.
not hub: A network hub, or a repeater, is a simple network device that does not manage any of the traffic coming through it. Any packet entering a port is flooded out or “repeated” on every other port, except for the port of entry.
