When two DHCP servers control parts of the same IP address range, the arrangement is called what?

• A. Overlapping Scope
• B. Dual Scope
• C. Split Scope
• D. Coexistence

Answer: (C)

Dividing the subnet’s IP pool between two DHCP servers is called a split scope. The idea is to allocate different portions of the same address range to each server, so each one only hands out addresses from its own portion. For example, one server might offer 192.168.1.1 through 192.168.1.100 while the other serves 192.168.1.101 through 192.168.1.200. This setup gives redundancy—if one DHCP server fails, clients can still obtain addresses from the other—and can help balance load because each server handles a distinct subset of addresses. It’s different from overlapping scopes, where the address ranges aren’t clearly separated and could lead to conflicts, and it’s not typically described as a dual scope or coexistence.
