Best Device to Direct Traffic to Remote Sites: N10-007 Exam Answer

A network administrator needs to transmit traffic to geographically diverse sites to improve performance.

Which of the following devices would BEST direct traffic to the remote sites?

A.

Hub

B.

Bridge

C.

Switch

D.

Router.

D.

The best device for directing traffic to geographically diverse sites would be a router. Routers are network devices that operate at the network layer (layer 3) of the OSI model, and they are designed to connect different networks together.

A router makes decisions based on logical addresses (such as IP addresses) to determine the best path for data to travel between networks. It uses routing protocols, such as OSPF or BGP, to exchange information about network topology and to build a routing table that contains information about the best paths to different networks.

In the context of geographically diverse sites, routers can be used to connect multiple sites together over a wide area network (WAN) or the Internet. The router at each site would have a routing table that contains information about the best paths to reach the other sites, and it would forward traffic between the sites based on that information.

In contrast, hubs and bridges operate at the physical layer (layer 1) and data link layer (layer 2) of the OSI model, respectively, and they are primarily used to connect devices together within a single network segment. Switches operate at the data link layer (layer 2) and are used to connect devices within a single network segment and improve network performance by reducing collisions and increasing bandwidth. However, none of these devices are designed to connect geographically diverse sites together, making a router the best option for this scenario.
