Switched backbones

Which of the following is not true about Layer-3 switches?

They can only switch messages based on their data link layer addresses

Which of the following is true regarding switched backbones?

They place all network devices for one part of the building physically in the same room, often in a rack of equipment

Which of the following is not true about backbone networks?

They tend to use lower speed circuits than LANs

A _____________ type of BN is a new type of LAN/BN architecture made possible by intelligent, high speed switches that assign computers to LAN segments via software, rather than by hardware.

Virtual LAN

Routers:

require more management than switches

A _____________ type of BN segments (each of which has a special set of subnet addresses that can be managed by different network managers) each part of the network connected to the backbone.

routed backbone

Which of the following is not a way that a router differs from a switch?

routers can connect two or more networks that use the same data link protocol

Which of the following is not true about switched backbones

there are many more networking devices in a switched backbone network

translating packets from one protocol to another as they enter the BN

Switched backbone networks:

use a star topology with one device, usually a switch
