问题 Which of the following statements describe the network shown in the graphic?

选项 A、There are two broadcast domains in the network.
B、There are four broadcast domains in the network.
C、There are six broadcast domains in the network.
D、There are four collision domains in the network.
E、There are seven collision domains in the network.

答案A,E

解析 这是个广播域和冲突域的问题。首先我们需要知道HUB整体是一个广播域和冲突域,而交换机整体是一个广播域,每个接口都是一个冲突域。知道了这些,这个问题的答案就很明显了,有两个广播域和七个冲突域。都没有到Attalla的映射,所以也无法和Attalla建立连通性。
