What defines a DHCP scope?

• A. The range of IP addresses that can be leased to clients.
• B. The physical boundary of a network.
• C. A DNS zone.
• D. A firewall rule set.

Answer: (C)

A DHCP scope is the pool of IP addresses that the DHCP server can assign to clients. It defines the range (start to end) within a subnet from which addresses are leased, and it typically includes the associated network settings that clients receive, such as subnet mask, default gateway, and DNS servers. This scope ensures the server can hand out valid addresses without conflicts and manage address usage.

The other options don’t fit because the physical boundary of a network is a subnet or network segment, not the DHCP lease pool; a DNS zone is about domain name resolution in DNS, not IP address leasing; and a firewall rule set governs security rather than IP address assignment.
