第3题：

What are some of the characteristics of a typical VLAN arrangement, found throughout the Ezonexam switched LAN? (Select all that apply)

A. VLANs logically divide a switch into multiple, independent switches at Layer 2.

B. Trunk links can carry traffic for multiple VLANs.

C. VLAN implementation significantly increases traffic due to added trunking information.

D. A VLAN can span multiple switches.

E. VLANs typically increase the number of switches needed

F. VLANs typically decrease the number of switches needed


正确答案：ABD
A,B,D 解析：Explanation:
VLANs give you the power of making virtual LAN networks to subdivide collision domains into smaller units of functionality, without being limited by physical location.

A is correct because that is the exact function of a VLAN. B is correct because trunk links are used to carry traffic for multiple VLANs. D is correct because a VLAN can and often does span across multiple switches. VTP makes this possible.

Incorrect Answers:
C. Although trunking information does indeed add some level of overhead, the overall traffic overhead is greatly reduced though the use of VLANs.

E, F. The number of total switches needed in a network is the result of the number of devices on the entire LAN that need to be connected. Whether VLANs are used or not will have little, if any, impact on the total number of switches needed in a LAN.
