You have just been hired by to help their main office expand. The main offices have enhanced their wiring closets with some Layer 3 switches. The new distribution layer switch has been installed and a new access layer switch cabled next to it. Your task is to configure the distribution layer and access layer 
switch with VTP to share VLAN information， then to configure inter-VLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access layer switches. 
VTP Domain Distribution 
VLAN Ids 20 31 
IP Addresses 172.16.71.1/24 172.16.132.1/24 
These are your specific tasks： 
1. Configure the VTP information with the distribution layer switch as the VTP server 
2. Configure the VTP information with the access layer switch as a VTP client 
3. Configure VLANs on the distribution layer switch 
4. Configure inter-VLAN routing on the distribution layer switch 
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future. 
6. All VLANs and VTP configurations are to completed in the global configuration

单项选择题Refer to the exhibit. The command spanning-tree guard root is configured on interface Gi0 0 on both switch S2 and S5. The global configuration command spanning-tree uplinkfast has been configured on both switch S2 and S5. The link between switch S4 and S5 fails.  Will Host A be able to reach Host B？ （）

A.Yes. Traffic can pass either from switch S6 to S3 to S2 to S1， or， from switch S6 to S5 to S2 to S1.
B.No. Traffic will pass from switch S6 to S5 and dead-end at interface Gi 0/0.
C.No. Traffic will loop back and forth between switch S5 and S2.
D.Yes. Traffic will pass from switch S6 to S3 to S2 to S1.
E.No. Traffic will either pass from switch S6 to S5 and dead-end， or traffic will pass from switch S6 to S3 to S2 and dead-end.
