You are configuring a Windows 2000 DNS Server on your company network. The network consists of one Windows NT domain. You already have DNS installed on a Windows NT Server on the Windows NT domain. You want to use dynamic updates on a DNS database, but company management will not allow an upgrade or decommission of the Windows NT DNS server. All DNS information must be synchronized between the two DNS servers.
What do you do to accomplish these goals? (Choose three)
A. Create a standard primary zone on a Windows 2000 DNS Server and import the existing zone file.
B. Create a standard secondary zone on a Windows 2000 DNS Server.
C. Delete and re-create the primary zone on the NT DNS Server.
D. Delete the existing zone and create a new secondary zone on the NT DNS Server.
E. Configure the primary zone on the NT DNS Server as the master zone for the secondary zone on the Windows 2000 DNS Server.
F. Configure the secondary zone on the NT DNS Server to use the Windows 2000 Standard primary zone as its master zone.
你正在为公司的网络配置一台Windows 2000 DNS服务器,这个网络由一个Windows NT域组成,你已经在这个NT域内的一台Windows NT Server安装了DNS,你希望使用动态更新DNS数据库,但是公司管理层并不想要升级或者让这台Windows NT DNS服务器退休,所有的DNS信息必须在这两台DNS服务器间同步。
要做到这点,你需要怎么怎样去做?
题解:
DNS在解析名称查询时,为了提供可用性和容错功能,区域数据应该能够从网络中的多个DNS服务器获取。例如,如果采用单个DNS服务器,那么如果该服务器没有响应,名称查询将失败。如果有多个服务器被配置为驻留某区域,就需要利用区域传输功能,在配置为驻留该区域的所有服务器这间对区域数据进行复制和同步,即区域传输。
