You
work as a remote support technician. A user named Rick calls you for support. Rick wants to connect
his LAN connection to the Internet. Which of the following devices will you suggest that he use?

A.
Hub

B.
Repeater

C.
Bridge

D.
Switch

E.
Router

Explanation:
A router connects a WAN to a LAN. In the given scenario, Rick has to connect his LAN to
the Internet (a WAN). For this, you will recommend
that he use a router. A router is a network device that connects network segments in a routed
network. It ensures communication between
devices on different network segments by forwarding packets between network segments. Routers
operate at the network layer of the OSI
model.
Answer options B, A, and D are incorrect. These devices work at the physical layer (layer 1) and are
used to connect devices within a LAN.
Answer option C is incorrect. A bridge is an interconnectivity device that connects two local area
networks (LANs) or two segments of the
same LAN using the same communication protocols, and provides address filtering between them.
Users can use this device to divide busy

networks into segments and reduce network traffic. A bridge broadcasts data packets to all the
possible destinations within a specific
segment. Bridges operate at the data-link layer of the OSI model.
