1. Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on 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.

3.5.3 Troubleshooting VLAN Configurations
2 A network administrator is implementing VTP in a large campus LAN that contains one hundred switches. What are valid considerations for reliability and administration?
Using server mode on a single master switch and client mode on all other switches will provide the most fault tolerance for retaining VLAN information in all switches if power is lost on the network.
Using transparent mode on all switches will allow for efficient administration and prevent VLAN data loss from the loss of any single switch.
Configuring several switches in server mode will allow all VLANs to be entered from a single switch and preserve VLAN data if any of the switches or connections are lost.
Configuring one primary and one backup switch in server mode and all other switches in transparent mode will provide fault tolerance for the VLAN data and allow for efficient distribution of the VLAN configurations to all switches.

Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on 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.

Refer to the exhibit. What would happen if the network administrator moved the network cable of Host A from interface Fa0/1 to Fa0/3 on 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.
