DNS服务逆向查找出错原因解析（DNS services reverse lookup for error reasons）

DNS服务逆向查找出错原因解析（DNS services reverse lookup for error reasons） DNS服务逆向查找出错原因解析(DNS services reverse lookup for error reasons) 问题:你是太平洋的网络管理员。您将Windows 2000服务器计算机配置为网络的DNS服务器。你创建了标准主要正向查找和反向查找区域，你会发现当你使用nslookup实用，不能解决从IP地址的主机名在你的网络。你还会发现，当你运行tracert.exe效用，您收到以下错误消息。”无法解析目标系统名称。“配置DNS向外部DNS安装WINS服务器提出请求和配置DHCP发行的WINS服务器的IP地址的所有DHCP客户端创建PTR(指针)在你的反向查找区域D.记录复制systemroot \ System32 \ \ \样本DNS缓存“cache.dns到systemroot \ System32 \ \ \ cache.dns DNS缓存作为一名太平洋的员，你配置了一台Windows 2000 Server作为网络的DNS服务器。你创建了标准主区域的正向查找与逆向查找，但你发现当你在局域网络中使用nslookup命令行时，不能够将IP地址解析为主机名称，而当你使用tracet .exe命令时，收到了这样的提示”无法解决目标系统的名称。”解答:Tracert命令是用来通往远程系统的路由状况的，它必需将主机名解析为IP地址以及将IP地址解析为主机名来运行，如果tarcert不能够工作，看起来很像是反向查找机制没有工作的原因。nslookup命令行使用逆向查找来查询并返回主机名称。逆向查找区域虽然建立了，但逆向查找区域并没有被激或者其中并没有PTR记录，通常就是这种原因造成上述问题的出现。正确答案:C tracert命令通过发送互联网控制消息(ICMP)回响请求和回响答复消息(类似于平命令)，产生关于经过的每个路由器的命令行输出以及每个跃点的往返时间(RTT)，从而跟踪路径。路由器、防火墙或其他类型性网关上的数据包筛选策略可能会阻止该通信的转发nslookup.exe是命令行管理工具，用于测试或解决DNS服务器问题。nslookup.exe可以在两种模式下运行:交互式和非交互式。当需要返回单块数据时，请使用非交互式模式。非交互模式的语法如下:要 在交互模式下启动nslookup。exe，只需在命令提示符下输入 nslookup:默认服务器:nameserver1.domain.com参考资料:MCSE trainking盒--微软Windows 2000网络基础设施管理——八使用 Windows 2000 DNS服务器--教训5:监控和故障排除的DNS网络密钥 交换鉴别方法问题:你是一个网络管理部件。你知道因特网密钥交换 (IKE)是/ oakley.but树认证方法你可以用像是什么ISAKMP新学 期,a.ipsec啊b.ipsec ESP d.pre-shared关键e.x.509证F.

Answer: X.509 Version3 certificate, the pre shared key (Pre-shared key) answer: CDE reference: E Kit -- Microsoft Training Windows 2000 Network Infrastructure Administration Chapter Securing Network Protocoles 10 - Lesson 2 Using IPSec You are the administrator of: PConline's network. You configure a Windows computer as the DNS 2000 Server server for your network. You create both standard primary forward lookup and reverse lookup zones.You discover that when you use the NSLOOKUP utility, you cannot resolve host names from IP addresses on your network. You also discover that when you run the Tracert.exe utility, you receive the following error message. Unable to resolve target system name. A. Configure the DNS to forward " Requests to an external DNS B. Install a WINS server and configure DHCP to issue the IP address of the WINS server to all DHCP clients C. Create PTR (pointer) records in your reverse lookup zone D. Copy the systemroot\system32\dns\cache\samples\ cache.dns to systemroot\system32\dns\cache\cache.dns as a PConline member, you configure a Windows 2000 Server as the network DNS server. You create a standard primary forward lookup zones and reverse lookup, but you find that when you use the NSLOOKUP in the local area network in the command line, can not be the IP address resolution for the host name, and when you use the Tracet.exe command, received such a message "Unable to resolve target system name." answer: the Tracert command is the remote system is used to route the situation, it is necessary to resolve host names to IP address and IP address resolution for the host name to run, if tarcert can not work, looks like is a reverse lookup mechanism does not work. The Nslookup command line uses reverse lookup to query and return the host name. The reverse lookup area has been established, but the reverse lookup area has not been stimulated, or there is no PTR record, and this is usually the cause of the problem. Answer: C tracert command by sending an Internet control message protocol (ICMP) echo request and echo reply message (similar to the ping command), produced on each router through the command line and report output per hop round-trip time (RTT), and path tracking. Packet filtering policies on routers, firewalls, or other types of gateways may block the communication's forward Nslookup.exe, which is a command line management tool for testing or solving DNS server problems. Nslookup.exe can run in two modes: interactive and non interactive. Use non interactive mode when you need to return a single block of data. The syntax for non interactive patterns is as follows:
