Simulation test system

It is necessary to strictly plan the reasonable allocation of GB0-372 test time in advance. Many students did not pay attention to the strict control of time during normal practice, which led to panic during the process of examination, and even some of them are not able to finish all the questions. If you purchased H3CSE-RS-SW learning tool, each of your mock exams is timed automatically by the system. GB0-372 exam learning materials provide you with an exam environment that is exactly the same as the actual exam. It forces you to learn how to allocate exam time so that the best level can be achieved in the examination room. At the same time, GB0-372 test question will also generate a report based on your practice performance to make you aware of the deficiencies in your learning process and help you develop a follow-up study plan so that you can use the limited energy where you need it most. So with GB0-372 study tool you can easily pass the exam.

H3CSE-RS-SW Sample Questions:

1. 拓扑如图,进行 STP 计算,正确的结果是:

A) 由于根桥 ID 、根路径开销、指定桥 ID 、指定端口均相同,故无法确定 SWD 的根端口
B) 如果将 SWD 的桥优先级设置为 0 ,则 SWD 将成为根桥,且端口 E0/1 和 E0/2 均为指定端口
C) SWD 需要通过比较自身接收配置 BPDU 的端口的 ID 来确定根端口
D) 如果将 SWD 的桥优先级设置为 0 ,则 SWD 的端口 E0/2 将只接收配置 BPDU 而不发送配置 BPDU

2. Overlay 技术如何解决云计算发展过程中遇到的问题与挑战 ? （选择一项或多项)

A) Overlay 把二层报文封装在 IP 报文之中,使得虚机可以跨越三层网络实现二层互通
B) Overlay 网络只需要边缘设备支持 Overlay 即可,中间 Underlay 网络可以使用传统设备,这样能保护已有投资,便于技术落地
C) Overlay 扩展了隔离标识位数,相较于使用 VLAN 来实现网络隔离, Overlay 网络的隔离能力获得极大提升
D) Overlay 网络的数据包对 Underlay 网络而言,仅仅只是隧道端点地址的转发,因而 Underlay 网络（特别是接入交换机)的 MAC 地址规格需求极大降低

3. 如图组网, SWA 和 SWD 启用 RSTP ,而 SWB 和 SWC 没有启用生成树协议,则下列说法正确的有

A) 当 SWB 的端口 EO/2DOWN 掉后, SWD 的端口 E0/2 会成为新的根端口并立即进入转发状态
B) SWD 将会有一个端口的角色为 Alternate
C) 当 SWB 的端口 EO/2DOWN 掉后, SWD 的端口 EO/2 会等待 3 个 Hello Time 后才会成为新的根端口并进入转发状态
D) 由于 SWB 和 SWC 没有启用生成树协议,所以当 SWD 的根端口 DOWN 掉后, Alternate 端口不能马上成为新的根端口并进入转发状态

4. 在如图所示的交换网络中,交换机 SWA 上设置 VLAN 10 为 Super VLAN , VLAN2 和 VLAN3 为 VLAN 10 的 Sub VLAN ,端口 Ethernet/0/3 为 Trunk 端口, PVID 为 VLAN1 ,允许所有 VLAN 通过；交换机 SWB 上创建 VLAN2~VLAN20 ,端口 Ethernet/0/4 为 Trunk 端口, PVID 为 VLAN1 ,允许所有 VLAN 通过,按照如图所示设置好各设备的 IP 地址后,在 SWB 上查看 MAC 地址表,可以判断 PCA 属于

A) VLAN 1
B) VLAN2
C) VLAN 10
D) VLAN3

5. 在 PIM-DM 组网中,关于路由器发送 Graft （嫁接)消息,描述正确的有。（选择 - 项或多项)

A) 路由器会将收到 Graft 消息的接口添加至组播表项的出接口列表中
B) 收到 Graft 消息的路由器会回复 Graft-ACK 消息,此消息目的地址为 224.0.0.13
C) Graft 消息为单播方式发送,目的地址为 RPF 邻居的 IP 地址
D) 被剪枝的路由器收到接收者发送的 IGMP Report 报文会向 RPF 邻居发送 Graft 消息
E) 被剪枝的路由器上出现组播接收者时,路由器不必等待下一次泛洪时才能将组播数据转发给接收者
