求助-CCNA题-VLAN相关
Which three statements are typical **acteristics of VLAN arrangements? (Choose three.)A. A new switch has no VLANs configured.
B. Connectivity between VLANs requires a Layer 3 device.
C. VLANs typically decrease the number of collision domains.
D. Each VLAN uses a separate address space.
E. A switch maintains a separate bridging table for each VLAN.
F. VLANs cannot span multiple switches
答案是 BDF， 我想问下 C 为什么不对，vlan 就是能减少冲突域啊？ 为什么不对呀
谢谢 因为交换机的每个接口都是一个冲突域，那么vlan的划分也就没有所谓的隔绝冲突域的作用的了，也就相当于不能减少冲突域了。 谢谢楼上，明白了！！ 学习了，谢谢！
