13 Refer to the exhibit. What would happen if the network administrator moved the network cableA 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 assigneVLAN 30.

Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignfor the port.

Host A maintains connectivity to all members of VLAN 10, because it is connected to the saphysical network.

Host A is no longer a member of VLAN 10, but because port Fa0/3 was unused, it is now amember of VLAN 1.

14 Refer to the exhibit. All hosts are in listen mode. Host 1 and Host 4 both transmit data at the satime. How do the hosts respond on the network? (Choose two.)

After the end of the jam signal, a backoff algorithm is invoked.

The hub will block the port connected to Host 4 to prevent a collision.

Hosts 1 and 4 are assigned shorter backoff values to provide them priority to access the m
