How does a DHCP server dynamically assign IP address to host?
Select one:
Addresses are allocated after a negotiation between the server and the host to determine the
length of the agreement.
Addresses are permanently assigned so that the host uses the same address at all times.
Addresses are assigned for a fixed period of time. At the end of period, a new quest for an
address must be made, and another address is then assigned.
Addresses are leased to host. A host will usually keep the same address by periodically
contacting the DHCP sever to renew the lease.
