问题 Refer to the exhibit． How many broadcast domains exist in the exhibited topology?

选项 A、one
B、two
C、three
D、four
E、five F． s i x

答案C

解析广播域的问题，在默认的情况下，每个交换机是不能隔离广播域的，所以在同一个区域的所有交换机都在同一个广播域中，但是为了减少广播的危害，将广播限制在一个更小的范围，有了VLAN的概念，VLAN表示的是一个虚拟的局域网，而他的作用就是隔离广播。所以被VLAN隔离了的每个区域都表示一个单独的广播域，这样一个VLAN中的广播的流量是不能传到其他的区域的，所以在上题中就有3个广播域了。
