What will be the result of adding the command ip dhcp excluded-address 172.16.4.1 172.16.4.5 to the configuration of a local router that has been configured as a DHCP server?
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.

What benefit does NAT64 provide?
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.
