H3C Constructing H3C High-Performance Campus Networks Sample Questions:
1. 下面关于三层交换机的说法正确的是
A) 三层交换机在功能上实现了 VLAN 的划分、 VLAN 内部的二层交换和 VLAN 间路由的功能
B) 三层交换机中包含二层 VLAN 转发引擎和三层转发引擎两个部分
C) 三层交换机的三层转发引擎就相当于传统组网中的路由器的功能,使用硬件 ASIC 技术实现跨网段的三层路由转发
D) 三层交换机上实际上结合了二层交换机和路由器的部分功能,提高了网络集成度,增强了转发性能
2. 客户的局域网交换机 SWA 双上行连接交换机 SWB 和交换机 SWC ,通过 SmartLink 保证链路可靠性 SWA 交换机有如下配置:
[SWA-smlk-group1]smart-link flush enable control-vlan 10
SWB 交换机有如下配置 ?
[SWB-GigabitEthernet1/0/1]smart-link flush enable control-vlan 100
SWC 交 i 机有如下配置:
[SWC-GigabitEthernet1/0/1]smart-link flush enable control-vlan 100
如果交换机 SWA 交换机 SWB 交换机 SWC 互连接口允许所有 VLAN 通过,从上述信息可以得知
A) 更改 SWB 交换机、 SWC 交换机接收控制 VLAN 为 10 ,则 SWA 交换机 SmartLink 备份功能可正常实现
B) 更改 SWB 交换机、 SWC 交换机接收控制 vlan 为 10 , SWB 交换机、 SWC 交换机通过流量刷新 MAC 和 ARP
C) 不更改配置,则 SWA 交换机 SmartLink 备份功能无法实现
D) 不需要修改任何配置, SWA 交换机 SmartLink 备份功能可实现
3. 如图,最初 SWA 通过 E0/1 和 SWB 相连, SWB 通过端口 E0/2 和 SWC 相连, SWA 和 SWC 没有直接相连启用 STP 并等待其收敛后,将 SWA 和 SWC 连接,由此导致交换机端口 STP 状态的变化,关于此变化的正确描述有
A) SWB 的端口 E0/2 和 SWC 的端口 E0/2 都将在 Listening 状态和 Learning 状态各停留一个 Forward Delay 时长
B) SWC 的端口 E0/2 会从 Listening 状态直接进入 Forwarding 状态
C) SWA 的端口 E0/2 和 SWC 的端口 E0/1 都将在 Listening 状态和 Learning 状态各停留一个 Forward Delay 时长
D) SWB 的端口 E0/2 会从 Forwarding 状态直接进入 Blocking 状态
4. 当路由器收到组播数据后,査找组播转发表
A) 如果组播转发表中存在对应的( S , G )表项,且该报文实际到达的接口与表项中入接口相匹配,路由器转发组播数据
B) 如果组播转发表中不存在对应的( S , G )表项,路由器丢弃组播数据
C) 如果组播转发表中存在对应的( S , G )表项,但该报文实际到达的接口与表项中入接口不匹配,路由器丢弃组播数据
D) 如果组播数据 RPF 接口与( S , G )表项中的入接口不符,路由器会将表项的入接口更新为检査得到的 RPF
5. 通过査看 IGMP 组信息,可以了解到的内容有
A) 组播组第一个发送 Report 报文的主机地址
B) 路由器维护的组播组信息
C) 组播组 Report 报文个数
D) 组播组 IGMP 査询器
