The command "show ip dhcp binding" is the appropriate choice for verifying the IP address assignment in a DHCP configuration. This command provides vital information about the IP addresses that have been assigned to clients by the DHCP server. It displays a list of all dynamic addresses allocated, along with the MAC addresses of the clients that were assigned those IPs, the lease duration, and the remaining lease time. This information is crucial for network administrators when monitoring IP address allocations and troubleshooting connectivity issues. With this command, you can ascertain whether a device received the correct IP address, how many IP addresses are available, and whether any have been leased or are still available for allocation. The other commands do not specifically provide an overview of the DHCP bindings. For instance, "verify dhcp ip address" is not a standard command in Cisco IOS. "Show ip address" displays the IP address configuration of the router or switch interface but does not provide details regarding DHCP client allocations. Similarly, "show dhcp config" offers insight into the DHCP server's configuration but does not directly confirm which addresses have been assigned to clients. Thus, "show ip dhcp binding" is the most relevant and informative command for understanding DHCP client IP address assignments.
