Refer to the exhibit. On the basis of the output of the show spanning-tree inconsistentports command，
which statement about interfaces FastEthernet 0/1 and FastEthernet 0/2 is true？（）
A.They have been configured with the spanning-tree bpdufilter disable command.
B.They have been configured with the spanning-tree bpdufilter enable command.
C.They have been configured with the spanning-tree bpduguard disable command.

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？（）
A.All ports of the root switch SW_A will remain in forwarding mode throughout the reconvergence of the spanning tree domain.
B.Switch SW_A will change its spanning tree priority to become root for VLAN 2 only.
C.Switch SW_A will remain root for the default VLAN and will become root for VLAN 2.
D.No other switch in the network will be able to become root as long as switch SW_A is up and running.
Refer to the exhibit. The command switchport mode access is issued on interface FastEthernet0/13 on switch CAT1.
What will be the result？（）
A.The command will be rejected by the switch.
B.Interfaces FastEthernet0/13 and FastEthernet0/14 will no longer be bundled.
C.Dynamic Trunking Protocol will be turned off on interfaces FastEthernet0/13 and FastEthernet0/14.
D.Interfaces FastEthernet0/13 and FastEthernet0/14 will only allow traffic from the native VLAN.
E.Interfaces FastEthernet0/13 and FastEthernet0/14 will continue to pass traffic for VLANs 88，100，360.
Refer to the exhibit.
What will happen when one more user is connected to interface FastEthernet 5/1？ （）
A.All secure addresses will age out and be removed from the secure address list. This will cause the security violation counter to increment.
B.The first address learned on the port will be removed from the secure address list and be replaced with the new address.
C.The interface will be placed into the error-disabled state immediately， and an SNMP trap notification will be sent.
D.The packets with the new source addresses will be dropped until a sufficient number of secure MAC addresses are removed from the secure address list.
Refer to the exhibit. LACP has been configured on Switch1 as shown.

B.Switch2# configure terminal Switch2（config）# interface range gigabitethernet3/1 -2 Switch2（config-if）# channel-group 5 mode passive
C.Switch2# configure terminal Switch2（config）# interface range gigabitethernet3/1 -2 Switch2（config-if）# channel-group 5 mode desirable
D.Switch2# configure terminal Switch2（config）# interface range gigabitethernet3/1 -2 Switch2（config-if）# channel-group 5 mode on

Refer to the exhibit. Switch 15 is configured as the root switch for VLAN 10 but not for VLAN 20. If the STP configuration is correct，
what will be true about Switch 15？（）
A.All ports will be in forwarding mode.
B.All ports in VLAN 10 will be in forwarding mode.
C.All ports in VLAN 10 will be in forwarding mode and all ports in VLAN 20 will be in blocking mode.
D.All ports in VLAN 10 will be in forwarding mode and all ports in VLAN 20 will be in standby mode.
A.BPDU port-guard can be enabled globally， whereas BPDU filtering must be enabled on a per-interface basis.
B.When globally enabled， BPDU port-guard and BPDU filtering apply only to PortFast enabled ports.
C.When globally enabled， BPDU port-guard and BPDU filtering apply only to trunking-enabled ports.
D.When a BPDU is received on a BPDU port-guard enabled port， the interface goes into the err-disabled state.
E.When a BPDU is received on a BPDU filtering enabled port， the interface goes into the err-disabled state.
F.When a BPDU is received on a BPDU filtering enabled port， the interface goes into the STP blocking state.
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？（）
A.The root port on switch SW_A will automatically transition to full-duplex mode.
B.The root port on switch SW_B will fallback to full-duplex mode.
C.The interfaces between switches SW_A and SW_B will transition to a blocking state.
D.Interface Fa 0/6 on switch SW_B will transition to a forwarding state and create a bridging loop.
