Hello,
Based on your needs, you can group multiple DHCP servers into a failover cluster, and these servers will work together to provide a highly available environment. In this environment, the server that plays the role of the active node will provide services to the client. If it fails, the server that plays the role of the passive node will take over and continue to provide services to the client.
