Port Mode Encapsulation Status Native VLAN
fa0/1 desirable n-802.1q trunking 5
Port VLANs is allowed on trunk
fa0/ 1 1-100， 102-1005
Port VLANs is owned and active in management domain
fa0/1 1-6. 8-100， 102-115， 197-999， 1002-1005
Port VLANs in spanning tree forwarding state and not pruned
fa0/1 1-6， 8-100， 102-105， 108-999， 1002-1005

Refer to the exhibit. All network links are FastEthernet. Although there is complete connectivitythroughout the network， Front Line users have been complaining that they experience slowernetwork performance when accessing the server farm than the Reception office experiences.Based on the exhibit， which two statements are true？（）
A.Disabling the Spanning Tree Protocol would improve network performance
B.Changing the bridge priority of S1 to 36864 would improve network performance
C.Changing the bridge priority of S1 to 4096 would improve network performance
D.Changing the bridge priority of S3 to 4096 would improve network performance
E.Upgrading the link between S2 and S3 to Gigabit Ethernet would improve performance
F.Changing the bridge priority of S2 to 36864 would improve network performance
The switched LAN is displayed below：
In this network， STP has been implemented. Switch SW1 is the root switch for the default VLAN.To reduce the broadcast domain， the network administrator decides to split users on the networkinto VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 rootprimary on switch SW1. What will happen as a result of this change？（）
A.Switch SW1 will change its spanning tree priority to become root for VLAN 2 only
B.All ports of the root switch SW1 will remain in forwarding mode throughout the reconvergenceof the spanning tree domain
C.No other switch in the network will be able to become root as long as switch SW1 is up andrunning
D.Switch SW1 will remain root for the default VLAN and will become root for VLAN 2
E.None of the other alternatives apply
