3 Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/switch SW1? Host A remains a member of VLAN 10, because the router is routing traffic between VLANs. Host A is no longer a member of VLAN 10, because port Fa0/3 has been manually assigned to VLAN 30. Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for

the port. Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network. Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now a member of VLAN 1. 4
