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.
Based on the show spanning-tree vlan 200 output shown in the exhibit，
which two statements about the STP process for VLAN 200 are true？ （）
A.BPDUs will be sent out every two seconds.
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.BPDUs will be sent out every 10 seconds.
A.HSRP
B.GLBP

D.SLB
E.RPR
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.
Examine the diagram. A network administrator has recently installed the above switched network using 3550s and would like to control the selection of the root bridge.
Which switch should theadministrator configure as the root bridge and which configuration command must theadministrator enter to accomplish this？（）
A.DSW11（config）# spanning-tree vlan 1 priority 4096
B.DSW12（config）# set spanning-tree priority 4096
C.ASW13（config）# spanning-tree vlan 1 priority 4096
D.DSW11（config）# set spanning-tree priority 4096
E.DSW12（config）# spanning-tree vlan 1 priority 4096
F.ASW13（config）# set spanning-tree priority 4096
Given the above diagram and assuming that STP is enabled on all switch devices，
which two statements are true？（）
A.DSW11 will be elected the root bridge.
B.DSW12 will be elected the root bridge.
C.ASW13 will be elected the root bridge.
D.P3/1 will be elected the nondesignated port.
E.P2/2 will be elected the nondesignated port.
F.P3/2 will be elected the nondesignated port.
A.Upon bootup，a port transitions from blocking to forwarding because it assumes itself as root.
B.Upon bootup，a port transitions from blocking to listening because it assumes itself as root.
C.Upon bootup，a port transitions from listening to forwarding because it assumes itself as root.
D.If a forwarding port receives no BPDUs by the max_age time limit， it will transition to listening.
E.If a forwarding port receives an inferior BPDU， it will transition to listening.
F.If a blocked port receives no BPDUs by the max_age time limit， it will transition to listening.
In a customer’s network， VLAN Trunking Protocol （VTP） is running with a domain named main1. VLANs 1，2，3，4，5，10，20 are active on the network. Suddenly the whole network goes down. No traffic is being passed on VLANs 2，3，4，5，10，20， however traffic passes on VLAN 1 and indicates all switches are operational. Right before the network problem occurred， a switch named TEST1 was added to the network.
What three configuration issues on TEST1 could be causing the network outage？（）
A.TEST1 is configured as a VTP server with a different domain name.
B.TEST1 is not configured to participate in VTP.
C.TEST1 is configured as a VTP server with the domain name main1.
D.TEST1 has a lower VTP configuration revision than the current VTP revision.
E.TEST1 has a higher VTP configuration revision than the current VTP revision.
F.TEST1 is configured with only VLAN1.

What is the configured priority value of the Vlan105’s group on DS2 ？（）
Refer to the exhibit and the partial configuration of switch SW_A and SW_B. STP is configured on all switches in the network. SW_B receives this error message on the console port：00：06：34： %CDP-4-DUPLEX_MISMATCH： duplex mismatch discovered on FastEthernet0/5 （not half duplex）， with SW_A FastEthernet0/4 （half duplex） ， with TBA05071417（Cat6K-B） 0/4 （half duplex）. What would be the possible outcome of the problem？（）
Refer to the exhibit. STP has been implemented in the network. Switch SW_A is the root switch for the default VLAN. To reduce the broadcast domain， the network administrator decides to split users on the network into VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 root primary on switch SW_A. What will happen as a result of this change？（）
During routine maintenance， it became necessary to shutdown G1/0/1 on DS1 and DS2. All other interface were up. During this time， DS1 became the active device for Vlan104’s HSRP group. As related to Vlan104’s HSRP group. What can be done to make the group function properly ？ （）
