第3题：

When comparing and contrasting the similarities and differences between bridges and switches, which of the following are valid statements? Choose all the valid answer choices)

A. Bridges are faster than switches because they have fewer ports.

B. A switch is a multiport bridge,

C. Bridges and switches learn MAC addresses by examining the source MAC address of each frame. received.

D. A bridge will forward a broadcast but a switch will not.

E. Bridges and switches increase the size of a collision domain.

F. None of the above statements are true.


正确答案：BC
B,C 解析：Explanation:
Both bridges and switches build the bridge table by listening to incoming frames and examining the source MAC address in the frame.

Switches are multiport bridges that allow you to create multiple broadcast domains. Each broadcast domain is like a distinct virtual bridge within a switch.

Incorrect Answers:
A. Switches are generally faster than bridges. Bridges also do not necessarily have fewer ports than switches.

D. Both bridges and switches will forward broadcast and multicast traffic, assuming that the traffic remains in the same VLAN.

E. The use of VLANs in a switch can decrease the size of the collision domain, by creating additional, smaller collision domains.
