D.
The correct answer is D) Lease time.
In Dynamic Host Configuration Protocol (DHCP), a server dynamically assigns IP addresses and network configuration information to clients. When a client requests an IP address from a DHCP server, the server assigns an IP address from a pool of available addresses and specifies a lease time. The lease time is the duration during which the client is allowed to use the IP address.
After the lease time expires, the client must request a new IP address lease from the DHCP server. If the lease time is too short, the client will frequently have to renew the lease, which can cause unnecessary network traffic. If the lease time is too long, the server may run out of available IP addresses for new clients.
The other answer choices are not correct in this context: A) MAC reservation is a technique used to assign a specific IP address to a client based on its MAC address. B) IP helper is a feature on network routers that can forward DHCP requests to DHCP servers on different subnets. C) Pool is a collection of IP addresses that can be assigned to clients by a DHCP server.
