    A

    该计算机IP地址设置有误

    B

    相关路由器上进行了访问控制

    C

    该计算机没有正确设置DNS服务器

    D

    该计算机设置的DNS服务器工作不正常


    正确答案: B
    解析:
    Tracert(跟踪路由)是路由跟踪实用程序,用于确定 IP 数据包访问目标所采取的路径。Tracert 命令用 IP 生存时间 (TTL) 字段和 ICMP 错误消息来确定从一个主机到网络上其他主机的路由。根据第四行语句“reports:Destination net unreachable”(远端网络不可到达)可知ICMP包不能通过路由器,因此可以推断相关路由器上设置了访问控制。因此答案选B。
