Question

Which of the following devices is used to connect multiple devices to a network and sends all traffic to all connected devices? (Please select one of the four options)

Switch

Modem

Hub

Repeater

Answer 1

Answer: HUB

Step-by-step explanation:

A Hub is a network device, that acts only in layer 1 (Physical layer) forwarding all traffic that reaches to the input port, to all output ports at once, without processing the received data in any way that could modify them.

It behaves like it were a multiport repeater (which has only one output port).
