Which of the following statements are true regarding bridges and switches? (Choose 3.)
A. Switches are primarily software based while bridges are hardware based.
B. Both bridges and switches forward Layer 2 broadcasts.
C. Bridges are frequently faster than switches.
D. Switches have a higher number of ports than most bridges.
E. Bridges define broadcast domains while switches define collision domains.
F. Both bridges and switches make forwarding decisions based on Layer 2 addresses.
Answer: BDF
Explanation/Reference:
A：交换机基于软件，网桥基于硬件，错误。都是基于硬件
B：都转发二层广播包，正确
C：网桥比交换机快速。错误。
D：交换机比网桥具有更多的端口，正确。
E：网桥定义广播域，交换机定义冲突域，错误。
F:基于二层地址转发数据。正确

E 这个选项怎么理解(不是怎么翻译)？

明王

网桥其实就相当于一台性能差一点，端口少一点的交换机，所以E是错的，两个都定义冲突域

毛毛虫

E选项的翻译应该是“ 网桥分割广播域，交换机分割冲突域”，交换机就是多口的网桥，因为网桥和交换机都只分割冲突域，不分割广播域，所以是错的。

提醒一下e文不要学死了。
