选项
答案B,C,E
解析 Explanation:
VLANs are used to segment a LAN into multiple, smaller LANs. This can be used to enhance security as local traffic from one VLAN will not be passed to users in other VLANS.

Incorrect Answers:
A. VLANs are used to decrease the size of a collision domain, not increase it.

D. The opposite is true.

F. The default operation of a switch is to allow all traffic and to enable all ports in VLAN1. The use of VLANs will increase the complexity of the switch environment, making for more difficult administration.
