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.
