某部门越来越多的用户抱怨DHCP服务器自动分配的IP地址不能获得因此,希望使用网络监视器来监视启用DHCP的客户和该DHCP服务器之间的通讯感兴趣的通信包时DHCP客户的请求和服务器的拒绝信号为了寻找排除故障的方法,应该监视以下哪些DHCP信息() A.DHCPDISCOVER和DHCPREQUESTB.DHCPREQUEST和DHCPNACKC.DHCPACK和DHCPNACKD.DHCPREQUEST和DHCPOFFER
本方案采用DHCP来分配网络地址。DHCP是(4)协议的一个扩展，便于客户自动从服务器获取IP地址和相关设置，其中实现IP地址动态分配的过程如下：(下面①到④未按顺序排列)①客户设置服务器ID和IP地址，并发送给服务器一个DHCPREQUEST报文。②客户端向服务器广播DHCPDISCOVER报文，此报文源地址为(5)，目标地址为(6)。③服务器返回 DHCPACK报文。④服务器返回 DHCPOFFER报文。客户收到的数据包中应包含客户的(7)地址，后面跟着服务器能提供的IP地址、子网掩码、租约期限以及DHCP服务器的(8)地址。客户进行ARP检测，如果觉得有问题，发送DHCPDECLINE报文；如果觉得没有问题，就接受这个配置参数。(1)将文中①～④按照应答过程重新排序。(2)将文中(4)～(8)处空缺的名称填写在答题纸的相应位置。
