7、寄存器的值是0x2102,这指示路由器加载IOS的引导方式将由路由器的配置文件所配置的引导顺序所决定，再结合图示中的systemimage file is “tftp: 172.16.1.129/hamption/nitro/c7200-j-mz”指示当前路由器是从TFTP服务器172.16.1.129下载的IOS镜像，所以答案A和E正确；从给出的图示中并不能看出R1作为另一台路由器的TFTP服务器，也无法看出R1无法从Flash里加载有效的IOS镜像，因为是指令要求R1从TFTP加载IOS镜像的，给出的图示中不是路由器的ROMMON模式，所以答案B、C、D都错误。英文原题2： Refer t

8、o the exhibit. A router boots to the prompt shown in the exhibit. What does thissignify, and how should the network administrator respond?rommon 1A.This prompt signifies that the configuration file was not found in NVRAM. The networkadministrator should follow the prompts to enter a basic configurat

9、ion.B.The prompt signifies that the configuration file was not found in flash memory. The networkadministrator should use TFTP to transfer a configuration file to the router.C.The prompt signifies that the IOS image in flash memory is invalid or corrupted. The networkadministrator should use TFTP to

10、 transfer an IOS image to the router.D.The prompt signifies that the router could not authenticate the user. The network administratorshould modify the IOS image and reboot the router.翻译：根据提供的图示，一台路由器启动提示符如下，这表示什么？网络管理员应该做出怎样的处理？rommon 1A.这个提示符表示在NVRAM里没找到配置文件，网络管理员应该在该提示符下输入基本配置B.这个提示符表示在Flash里没找到配

11、置文件，网络管理员应该使用TFTP传输配置文件到路由器C.这个提示符表示在Flash里的IOS镜像文件无效或被损坏，网络管理员应该使用TFTP传输一个IOS镜像到路由器D.这个提示符表示路由器无法验证用户，网络管理员应该修改IOS镜像并且重启路由器答案：Co可以看出给出的图示rommon表示路由器的监控模式，路由器引导进入这样的模式中，表示路由器Flash中的IOS镜像无效或者被破坏，管理员应该做的是通过TFTP服务器重新加载一个10S镜像到路由器的Flash中；出现rommon表示跟路由器的配置文件和验证用户都无关，所以答案A、B、D都错误。英文原题3： Refer to the exhib
