A. Host B would not be able to access the server in VLAN9 until the cable is reconnected.
B. Communication between VLAN3 and the other VLANs would be disabled.
C. The transfer of files from Host B to the server in VLAN9 would be significantly slower.
D. For less than a minute, Host B would not be able to access the server in VLAN9. Then normal network function would resume.
解释一下:在交换机间是有一个环路存在的,所以运行的生成树就会block一个端口,从而阻断环路的产生,所以端口f0/9就被block了,所以就没有了连通性。而生成树的选举过程在正常的情况下是需要至少50秒的。所以在生成树选举的过程中HOST B是不能访问到处于VLAN 9中的SERVER的。
169.Refer to the exhibit. The network istrator is in a campus building distant from Building B. WANRouter is hosting a newly installed W AN link on interface S0/0. The new link is not functioning and the istrate needs to determine if the correct cable has been attached to the S0/0 interface. How can the istrator accurately verify the correct cable type on S0/0 in the most efficient manner?
