Traffic that is destined for 172.16.4.1 and 172.16.4.5 will be dropped by the router.
Traffic will not be routed from clients with addresses between 172.16.4.1 and 172.16.4.5.
The DHCP server function of the router will not issue the addresses from 172.16.4.1 through 172.16.4.5 inclusive.
The router will ignore all traffic that comes from the DHCP servers with addresses 172.16.4.1 and 172.16.4.5.

The output is the result of the show ip nat translations command.
The host with the address 126.96.36.199 will respond to requests by using a source address of 192.168.10.10.
The host with the address 188.8.131.52 will respond to requests by using a source address of 184.108.40.206.
Traffic with the destination address of a public web server will be sourced from the IP of 192.168.1.10.
The output is the result of the show ip nat statistics command.
It allows sites to use private IPv6 addresses and translates them to global IPv6 addresses.
It allows sites to connect multiple IPv4 hosts to the Internet via the use of a single public IPv4 address.
It allows sites to connect IPv6 hosts to an IPv4 network by translating the IPv6 addresses to IPv4 addresses.
It allows sites to use private IPv4 addresses, and thus hides the internal addressing structure from hosts on public IPv4 networks.

Because there is a cabling problem on VLAN 99
Because VLAN 99 is not a valid management VLAN
Because VLAN 1 is up and there can only be one management VLAN on the switch
Because VLAN 99 has not yet been created
