After configuring a DHCP server, which command would you use to renew the IP address for a workstation?

Using the command "ipconfig /renew" is the appropriate choice for renewing the IP address for a workstation after configuring a DHCP server. This command instructs the DHCP client on the workstation to send a request to the DHCP server to obtain a new IP address or to renew its current lease on the existing IP address.

When a workstation is configured to use DHCP, it automatically requests its IP address and other network configuration settings from the DHCP server. Over time, the lease on the IP address might expire, or there could be a need to refresh the configuration. Executing the "ipconfig /renew" command initiates this process, allowing the workstation to continue communicating on the network without requiring manual configuration.

In contrast, other commands have different purposes. For example, "ipconfig /all" displays all current IP configuration settings but does not change anything. The "ipconfig /release" command would release the current DHCP lease, effectively dropping the workstation's IP address. The "ipconfig /flushdns" command is meant for clearing the DNS resolver cache but has no effect on IP addresses. Thus, by understanding the specific role of "ipconfig /renew," it becomes clear why this is the correct command to use in this scenario.
