    一台PC服务器,安装Linux并配置DNS服务。检查文件(44)发现内容为“order hosts”。

    A./etc/resolv.conf

    B./etc/host.conf

    C./etc/linux.conf

    D./etc/sys.conf


    正确答案:B
    解析:文件/etc/host.conf包含了为解析库声明的配置信息。它应该每行含一个配置关键字,其后跟着合适的配置信息。系统识别的关键字有:order、trim,multi、nospoof和reorder。/etc/resolv.conf为解析配置文件,/etc/hosts为本地主机数据库。
