Answer:
Reservation (Correct)
Step-by-step explanation:
DHCP reservation is a permanent IP address assignment. It is a specific IP address within DHCP scope that is permanently reserved for leased use to a specific DHCP client. Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment. Reservations are used for DHCP enabled devices like print and file servers or other application servers that always have the fixed IP address on the network.
