How many authoritative DHCP servers can you have on a network?

• A. One
• B. Two
• C. No limit
• D. Limited by subnet size

Answer: (C)

Having multiple authoritative DHCP servers is a common design for reliability and scalability. The DHCP protocol itself does not set a fixed cap on how many servers can be authoritative on a network. You can deploy many servers across subnets, and you can even have additional authoritative servers for the same subnet by using mechanisms like failover or coordinated scope management so lease data is shared and conflicts are avoided. The practical limit isn’t a protocol rule but your hardware, management effort, and the chosen high-availability approach. So there is no hard limit on the number of authoritative DHCP servers you can have on a network.
