H3CSE-RS-SW Sample Questions:
Question #1
关于 MSTP 的基本概念,说法正确的有
A. 默认情况 MST 域内的所有 VLAN 都映射到 IST
B. CST 运行时,将 MST 域视为逻辑上的一台交换机, CST 的根桥为总根所属的域
C. CST 是指域之间的一棵生成树,它是 MST 域之间运行 STP/RSTP 得到的
D. IST 是 MST 域内的一棵生成树, IST 对应的实例号为 0
Question #2
模块化网络构架的优点包括（选择一项或多项)
A. 对每一模块可以分别进行规划和部署。可以通过增删模块的方式增加或去除网络的功能,有利于构建复杂的网络
B. 允许不同应用功能或应用系统之间共享数据、资源和能力,参与业务流程
C. 允许通过开放的接口来动态调用 IT 资源,实现标准、兼容、安全、智能和可管理的 IT 应用环境
D. 取代了传统的层级化网络模型,便于进行网络的规划和部署
Question #3
以下关于 OpenFlow 的说法,哪个是正确的 ? （选择 - 项或多项)
A. Hello 消息用于 OpenFlow 保活
B. OpenFlow 定义的众多 Action 里面, drop 的含义为直接丢弃
C. OpenFlow 信道可以使用 TLS 加密
D. Feature Request 消息用于协商 OpenFlow 版本
Question #4
客户的二台交换机 SWA 、 SWB 通过七根以太网线连接在一起 , 并配置了动态链路聚合 , 交换机 SWA 上对应端口为 Ethernet 1/0 Ethernet 1/0/2 、 Ethernet 1/0/3 、 Ethernet 1/0/4 、 Ethernet 1/0/5 、 Ethernet 1/0/6 、 Ethernet1/0/7
如果交换机 SWA 、 SWB 每个聚合组只支持 6 个端口,且 SWA 交换机有如下配置:
[SWA] interface Ethernet 1/0/7
[SWA-Ethernet1/0/7] lacp port-priority 4096 i
设备上查看 LACP 状态输出如下:
[SWA] display lacp system-id
Actor System ID: 0x8000 , 00e1-fc00-5000
[SWB] display lacp system-id
Actor System ID: 0x8000 , 00e0-fc43-7384
从上述信息可以得知
A. 在各端口配置 - 致的情况下, Ethernet1/0/6 端口为聚合组 Unselected 端口
B. 在各端口配置 - 致的情况下, Ethernet1/0/7 端口为聚合组 Unselected 端口
C. 在各端口配置 - 致的情况下, Ethernet1/0/2 端口为聚合组 Unselected 端口
D. 在各端口配置一致的情况下, Ethernet1/0/1 端口为聚合组 Unselected 端口
Question #5
关于生成树配置中的 stpmcheck 命令,说法正确的有
A. 通过在 RSTP 或 MSTP 交换机的端口上运行该命令,可以将端口的生成树模式切换到 STP
B. 该命令用于 RSTP 交换机和 MSTP 交换机互连时使用
C. 该命令在不同厂商的交换机互连,且运行 MSTP 时使用,用于检查摘要信息
D. 该命令用于运行 RSTP 或 MSTP 的交换机端口连接 STP 设备时使用
