The correct answer is A. DHCP scope.
A DHCP scope is a consecutive range of IP addresses that a DHCP server can select from to fulfill requests from network clients. A DHCP server is a device that automatically assigns IP addresses and other network configuration parameters to devices that request them. A DHCP scope defines the pool of available IP addresses, as well as the subnet mask, default gateway, DNS servers, and lease duration for each IP address. A DHCP scope can also include exclusions, reservations, and policies to customize the IP address allocation process12.
A static IP list is a list of IP addresses that are manually assigned to devices and do not change over time. A static IP list does not require a DHCP server, but it requires more administrative effort and coordination to avoid conflicts or errors. A static IP list is not a consecutive range of IP addresses that a server can select from3.
DNS A records are DNS records that map a domain name to an IPv4 address. DNS is a system that translates human-readable domain names into machine-readable IP addresses. DNS A records are not a range of IP addresses that a server can select from, but a way of resolving domain names to IP addresses.
Automatic private IP addressing (APIPA) is a feature of Windows that allows devices to self-assign an IP address in the absence of a DHCP server or a static IP configuration. APIPA uses the 169.254.0.0/16 address range, which is reserved for link-local communication. APIPA does not create a range of IP addresses that a server can select from, but a fallback mechanism for devices that cannot obtain an IP address from another source.
