请参见图示。下列哪组设备仅包含中间设备？ A、B、D、G A、B、E、F C、D、G、I G、H、I、J
2
您所在的网际网络发生了路由问题。要鉴别此错误，应该检查以下哪种类型的设备？ 接入点 主机
集线器 路由器 交换机
3
请参见图示。技术人员正在处理网络问题，需要验证路由器的 LAN 接口。要确认路由器接口工作正常，应该从此主机 ping 哪个地址？ 127.0.0.1 192.168.64.196 192.168.254.1 192.168.254.9 192.168.254.254
4
下列哪三项陈述说明了传输层协议的特征？（选择三项） 应用层协议使用 TCP 端口号和 UDP 端口号。 TCP 使用端口号提供可靠的 IP 数据包传输。 UDP 使用窗口和确认获得可靠的数据传输。 TCP 使用窗口和定序提供可靠的数据传输。 TCP 是面向连接的协议。UDP 是无连接协议。
5
OSI 模型的哪两项功能在第 2 层实现？（选择两项） 物理编址 编码 路由
布线 介质访问控制
6
由于发生安全规规事件，必须更改路由器口令。从以下配置项可获知什么信息？（选择两项。）
Router(config)#line vty 0 3
Router(config-line)# password c13c0 Router(config-line)#login
这些配置项对远程访问指定了三条 Telnet 线路。 这些配置项对远程访问指定了四条 Telnet 线路。
这些配置项将控制台口令和 Telnet 口令设置为 \。 因为 Telnet 配置不完整，所以 Telnet 访问将遭到拒绝。 允许使用 \作为口令访问 Telnet。
7
请参见图示。电缆 1 和电缆 2 的两端分别按照特定的物理层要求接线。表中按编号列出了每个网段以及网络技术人员在该网段不同网络组件之间已经安装的电缆。根据给定的数据回答，哪些网段的电缆安装正确？（选择三项） 网段 1 网段 2 网段 3
