Why each option
The `show ip dhcp conflict` command is used on Cisco devices to display any IP address conflicts detected by the DHCP server, indicating potential duplicate assignments.
On Cisco IOS devices, the `show ip dhcp conflict` command displays a list of IP addresses that the DHCP server has detected as being in conflict, typically when a host tries to use an address already in use or the server itself assigns an address that is already active on the network.
The `show ip dhcp database` command (or similar variants) is used to display the DHCP lease database information, not conflicts.
The `show ip dhcp server statistics` command displays operational statistics of the DHCP server, such as message counts, but not specific conflict entries.
The `show ip dhcp binding` command displays the current active IP address bindings (leases) made by the DHCP server, not conflicts.
