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

The Dynamic Host Configuration Protocol provides configuration parameters to Intemet （ ）. DHCP consists of two components: a （ ） for delivering host-specific configuration parameters from a DHCP server to a host and a mechanism for allocation of network addresses to hosts. DHCP is built on a client-server model, where designated DHCP server hosts allocate network addresses and deliver （ ） parameters to dynamically configured hosts. DHCP supports three mechanisms for IP address allocation. In automatic allocation, DHCP assigns a （ ） IP address to a client. In dynamic allocation, DHCP assigns an IP address to a client for a limited period of time. In manual allocation, a clients IP address is assigned by the network （ ）, and DHCP is used simply to convey the assitped address to the client.A.switchB.termmalC.hostsD.usersA.routerB.protocolC.hostD.mechanismA.controlB.broadcastC.configurationD.transmissionA.permanentB.dynamicC.cormectionD.sessionA.controllerB.userC.hostD.administrator
Refer to the exhibit. Which statement is true about the configuration?() A. Hosts belonging to DHCP pool 1 and pool 2 will retain their IP settings for 30 hours before they must renew.B. Hosts will receive IP settings from pool 1 until the addresses run out, and then hosts will receive the settings from pool 2.C. Hosts in the 10.10.20.0/24 subnet will u se 10.10.20.50 as its DNS server.D. DHCP pool 0 needs to have the ip dhcp excluded - address command to exclude the default router and DNS servers.
Which statement describes the process of dynamically assigning IP addresses by the DHCP server?() A.

Addresses are assigned for a fixed period of time, at the end of the period, a new request for an address must be made.D. Addresses are leased to hosts, which periodically contact the DHCP server to renew the lease.
