关于域名管理系统(Domain Name System)的说法不正确的是______。

A．其负责域名到IP的地址变换

B．是一个中央集权式的管理系统

C．实现域名解析要依赖于本地的DNS数据库

D．实现域名解析要依赖于域名分解器与域名服务器这两个管理软件

答案

参考答案：B

解析：[知识点] Internet通信协议——TCP/IP
[评析] 域名管理系统是一个按层次组织的分布式服务系统，不是一个中央集权式的管理系统。其内部数据库的建立与维护任务被分配到各个本地协作者网络机构。增加主机、改变主机名称、重新设置IP及数据库的更新都是本地数据库的事情。因此B说法是错误的，其他说法均是正确的。
