It allows sites to connect multiple IPv4 hosts to the Internet via the use of a single public IPv4 address.

It allows sites to use private IPv6 addresses and translates them to global IPv6 addresses.

It allows sites to use private IPv4 addresses, and thus hides the internal addressing structure from hosts on public IPv4 networks.

An administrator is trying to remove configurations from a switch. After using the command erase startup-config and reloading the switch, the administrator finds that VLANs 10 and 100 still exist on the switch. Why were these VLANs not removed?

These VLANs are default VLANs that cannot be removed.

These VLANs cannot be deleted unless the switch is in VTP client mode.

Because these VLANs are stored in a file that is called vlan.dat that is located in flash memory, this file must be manually deleted.

These VLANs can only be removed from the switch by using the no vlan 10 and no vlan 100 commands.

The ip address dhcp command was not issued on the interface Gi0/1.

The ip helper-address command was applied on the wrong interface.
