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
