H3C Constructing Small - and Medium - Sized Enterprise Network Sample Questions:
1. 路由器 MSR-1 、 MSR-2 通过各自的 GigabitEthernet0/0 互连,同时两台路由器之间运行了 RIP ,目前 RIP 已经正确完成了远端路由学习,现在在 MSR-1 的路由表中看到如下的路由信息:
Destination/Mask Proto Pre Cost NextHop Interface
2.0.0.0/24 RIP 100 15 100.1.1.1 GE0/0
6.0.0.0/8 RIP 100 1 100.1.1.1 GE0/0
那么据此信息可以推测 ______ 。
A) 可以确认两台路由器之间运行的是 RIPv2
B) 第一条目的网段为 2.0.0.0/24 的路由 Cost 已经达到最大值,是一条无效路由
C) 可以确认两台路由器之间运行是 RIPv1
D) 第一条目的网段为 2.0.0.0/24 的路由依然是一条有效路由
2. 在路由器 MSR-1 上看到如下信息:
[MSR-1]display acl 3000
Advanced ACL 3000, named -none-, 2 rules,
ACL's step is 5
rule 0 permit ip source 192.168.1.0 0.0.0.255
rule 10 deny ip (19 times matched)
该 ACL 3000 已被应用在正确的接口以及方向上。
据此可知 _______ 。(多选)
A) 匹配规则 rule 10 的数据包可能是去往目的网段 192.168.1.0/24 的
B) 这是一个基本 ACL
C) 有数据包流匹配了规则 rule 10
D) 至查看该信息时,还没有来自 192.168.1.0/24 网段的数据包匹配该 ACL
3. 以下关于星型网络拓扑结构的描述正确的是 ______ 。(多选)
A) 在星型拓扑中,某条线路的故障不影响其它线路下的计算机通信
B) 星型拓扑具有很高的健壮性,不存在单点故障的问题中心结点故障
C) 星型拓扑易于维护
D) 由于星型拓扑结构的网络是共享总线带宽,当网络负载过重时会导致性能下降
4. 两台空配置的 MSR 路由器通过各自的广域网 Serial1/0 接口背靠背直连,其互连网段为 192.0.0.0/24 。
同时两台路由器的通过各自的 GigabitEthernet0/0 连接各自的局域网段用户:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
在两台路由器上配置 RIPv1 ,现在两台路由器上都学习到了对端局域网段的 RIP 路由。那么如下哪些说法是正确的 ?
A) 两台路由器之间的 RIP 报文基于 TCP 传输
B) 两台路由器之间交互 RIP 报文的方式是组播方式
C) 可以在两台路由器的广域网接口上配置 CHAP 验证增强网络安全性
D) 如果其中一台路由器的局域网段为 10.0.0.0/24 ,那么在另外一台路由器的路由表将学习到 10.0.0.0/8 的路由
5. 两台 MSR 路由器 MSR-1 、 MSR-2 通过广域网连接并通过 RIPv2 动态完成了远端路由学习。
稳定了 2 分钟后,在 MSR-1 上接收到来自 MSR-2 的 RIP 更新报文,其中含有 Cost 为 14 的路由,那么 ______ 。(多选)
A) 如果 MSR-1 的路由表原本没有该路由,那么该路由一定会被加入 MSR-1 路由表
B) 如果 MSR-1 的路由表原本有该路由,而且其 Cost 小于 14 ,那么在 MSR-1 上该路由项不会更新
C) 如果 MSR-1 的路由表原本有该路由,仅当其 Cost 大于 14 时,该路由项才会被更新
D) 如果 MSR-1 的路由表中原本有从该邻居收到的相同路由,且其 Cost 小于 14 ,该路由也会被更新
