第1题：
在大型网络中，通常采用DHCP完成基本网络配置会更有效率。在Linux系统中，DHCP服务默认的配置文件为 (34) 。A.／etc／sbin／dhcpd.conf
B.／etc／dhcpd.conf
C.／var／state／dhcpd.config
D.／usr／sbin／dhcpd.config答案：B解析：在Linux操作系统中，与DHCP相关的主要配置文件如下：DHCP服务器配置文件／etc／dhcpD．conf，启动DHCP服务的脚本／etc／rC．d／ink．d／dhcpd，执行DHCP服务的程序／usr／sbin／dhcpd，记录客户端租用信息的文件／var／state／dhcpD．1eases。 -
