How does a DHCP server dynamically assign IP address to host?
Addresses are allocated after a negotiation between the server and the host to determine the length of the agreement.
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.
Addresses are permanently assigned so that the host uses the same address at all times.
Which statement is correct regarding the operation of DHCP?
A DHCP client uses a ping to detect address conflicts.
A DHCP server uses a gratuitous ARP to detect DHCP clients.
If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict.
If an address conflict is detected, the address is removed from the pool for an amount of time configurable by the administrator.
If an address conflict is detected, the address is removed from the pool and will not be reused until the server is rebooted.
