Refer to the exhibit. All network links are FastEthernet. Although there is complete connectivity throughout the network， Front Line users have been complaining that they experience slower network performance when accessing the server farm than the Reception office experiences. Based on the exhibit，
which two statements are true？（）
A.Changing the bridge priority of S1 to 4096 would improve network performance.
B.Changing the bridge priority of S1 to 36864 would improve network performance.
C.Changing the bridge priority of S2 to 36864 would improve network performance.
D.Changing the bridge priority of S3 to 4096 would improve network performance.
E.Disabling the Spanning Tree Protocol would improve network performance.
F.Upgrading the link between S2 and S3 to Gigabit Ethernet would improve performance.
A.The BID is made up of the bridge priority value（two bytes） and bridge MAC address （six bytes）.
B.The BID is made up of the bridge priority （four bits）， the system ID （12 bits）， and a bridge MAC address （48 bits）.
C.The BID is made up of the system ID （six bytes） and bridge priority value （two bytes）.
D.The system ID value is the VLAN ID （VID）.
E.The system ID value is a unique MAC address allocated from a pool of MAC addresses assigned to the switch or module.
F.The system ID value is a hex number used to measure the preference of a bridge in the spanning-tree algorithm.

B.The time spent in the listening state will be 30 seconds.
C.The time spent in the learning state will be 15 seconds.
D.The maximum length of time that the BPDU information will be saved is 30 seconds.
E.This switch is the root bridge for VLAN 200.

F.RPR+
A.STP timers values （hello， forward delay， max age） are included in each BPDU.
B.A switch is not concerned about its local configuration of the STP timers values. It will only consider the value of the STP timers contained in the BPDU it is receiving.
C.To successfully exchange BPDUs between two switches， their STP timers value （hello， forward delay， max age） must be the same.
D.If any STP timer value （hello， forward delay， max age） needs to be changed， it should at least be changed on the root bridge and backup root bridge.
E.On a switched network with a small network diameter， the STP hello timer can be tuned to a lower value to decrease the load on the switch CPU.
F.The root bridge passes the timer information in BPDUs to all routers in the Layer 3 configuration.
