问题 The Dynamic Host Configuration Protocol provides configuration parameters to Internet__________(71)．DHCP consists of two components：a___________(72)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___________(73)parameters to dynamically configured hosts．DHCP supports three mechanisms for IP address allocation．In"automatic allocation"，DHCP assigns a __________(74)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 client’S IP address is assigned by the network ___________(75)，and DHCP is used simply to convey the assigned address to the client．
(75)
选项 A、controller
B、user
C、host
D、administrator
答案D
解析 动态主机配置协议向因特网主机提供配置参数。DHCP由两个部分组成：一个用于从DHCP服务器向主机提交主机专用配置参数的协议，以及一种给主机分配网络地址的机制。DHCP建立在客户机．服务器模式上，专用的DHCP服务器负责分配网络地址，并且向动态配置的主机提交配置参数。DHCP支持3：种IP地址分配机制。在“自动分配”方式中，DHCP为客户指定一个固定的IP地址。在“动态分配”模式中，DHCP给客户分配一个仅在一定时间段内有效的IP地址。在“手工分配”模式中，客户的IP地址是由网络管理员指定的，DHCP只是把分配的地址转送给客户。
