A.VTP pruning has isolated the switch.
B.IP routing is disabled on the switch.
C.PoE is failing on the remote port.
D.There is a loop in the topology.

A.The command enables both loop guard and root guard.
B.The command changes the status of loop guard from the default of disabled to enabled.
C.The command activates loop guard on point-to-multipoint links in the switched network.
D.The command will disable EtherChannel guard.

A.Packets are distributed across the ports in the channel based on both the source and destination MAC addresses.
B.Packets are distributed across the ports in the channel based on both the source and destination IP addresses.
C.Packets are balanced across the ports in the channel based first on the source MAC address， then on the destination MAC address， then on the IP address.
D.Packets are distributed across the access ports in the channel based first on the source IP address and then the destination IP addresses.

A.network management
B.improving QoS
C.determining budget
D.reducing costs
E.increasing competitiveness
F.improving customer support

A.There are 20 neighbors in the EIGRP neigbor table.
B.EIGRP is running normally and receiving IPv4 routing updates.
C.The switch has not established any neighbor relationships. Further network testing and troubleshooting must be performed to determine the cause of the problem.
D.EIGRP status cannot be determined. The command show ip eigrp topology would determine the routing protocol status.
