You want to influence the root bridge selection within the Ezonexam LAN. Which two values are used by spanning tree protocol to elect a root bridge? (Choose two.)A. Amount of RAMB. Speed of the linksC. IOS VersionD. MAC AddressE. Bridge PriorityF. IP AddressG. Router ID
考题
Refer to the exhibit. Which statement is true?()
A.The Fa0/11 role confirms that SwitchA is the root bridge for VLAN 20.B.VLAN 20 is running the Per VLAN Spanning Tree Protocol.C.The MAC address of the root bridge is 0017.596d.1580.D.SwitchA is not the root bridge, because not all of the interface roles are designated.
考题
Refer to the exhibit. Why has this switch not been elected the root bridge for VLAN1?()
A.It has more than one interface that is connected to the root network segment.B.It is running RSTP while the elected root bridge is running 802.1d spanning tree.C.It has a higher MAC address than the elected root bridge.D.It has a higher bridge ID than the elected root bridge.
考题
Refer to the exhibit. Given the output shown from this Cisco Catalyst 2950, what is the most likely reason that interface FastEthernet 0／10 is not the root port for VLAN 2?()
A.This switch has more than one interface connected to the root network segment in VLAN 2.B.This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.C.This switch interface has a higher path cost to the root bridge than another in the topology.D.This switch has a lower bridge ID for VLAN 2 than the elected designated switch.
