What should you do after importing the DHCP settings on the destination server?

After importing the DHCP settings on the destination server, starting the DHCP service is essential because the service must be active for the DHCP server to assign IP addresses and manage the network configuration for clients. Once the settings are imported, the service can recognize the new configurations, including scopes and options that have been established during the import process.

If the DHCP service is not started, the server would not be able to respond to client requests for IP addresses, effectively making the import process futile. Thus, ensuring that the DHCP service is started immediately after importing the settings is critical for operational readiness.

Other options may be relevant in specific circumstances, such as running diagnostics to check for issues or configuring DHCP clients, but these actions are secondary to the immediate necessity of having the DHCP service running to fulfill its core function. Performing a reboot is also unnecessary after an import, as starting the service should suffice to activate the newly imported settings.
