第1题:

You need to configure an 802.1Q link on a Ezonexam switch. Which commands, when used together, would do this? (Select two answer choices)

A. Switch(vlan) mode trunk

B. Switch(config) switchport access mode trunk

C. Switch(config-if) switchport mode trunk

D. Switch(config-if) switchport trunk encapsulation dot1q

E. Switch(config) switchport access mode 1

F. Switch(vlan) trunk encapsulation dot1q


正确答案:CD
C,D 解析:Explanation:
Creating this trunk link is a two step process. First you have to set the switchport mode to trunk, and then you configure the encapsulation. The giveaway on this question is the fact that to create a trunk on an interface, you have to be in interface configuration mode. So switchport mode trunk sets the trunk, and switchport trunk encapsulation dot1q sets the encapsulation.

随着越来越多的机构为任务关键型通信寻求经济利益,高可靠性变得日益关键。网络通信注意力集中在提供一种7×24小时都可用的网络架构上。可是,最大的挑战之一不是来自于网络架构,而是来自于用户级的工作站和网络设备。

热备份路由选择协议(HSRP)为IP碉络提供了容错和增强的路由选择功能。如图5-1就是一个典型的HSRP网络的实现。

第6题:

The Ezonexam network administrator has issued the "VTP password ezonexam" command on a Cisco device. What is the purpose of this command?

A.It allows two VTP servers to exists in the same domain, each configured with different passwords

B.It is the password required when promoting a switch from VTP client mode to VTP server mode

C.It is used to access the VTP server to make changes to the VTP configuration

D.It is used to validate the sources of VTP advertisements sent between switches

E.None of the above


正确答案:D

第7题:

You are bringing up a new Ezonexam switch, and wish to connect it via a trunk to another switch from a different vendor, which uses the IEEE standard for the trunking method. When setting the encapsulation type on the trunk, what should you configure on the Cisco switch?

A.Switch(config)# switchport trunk encapsulation isl

B.Switch(config)# switchport trunk encapsulation ietf

C.Switch(config-if)# switchport trunk encapsulation isl

D.Switch(config-if)# switchport trunk encapsulation ietf

E.Switch(config-if)# switchport trunk encapsulation dot1q


正确答案:E
解析:Explanation:
The only real choices for setting up switching trunks are ISL and 802.1Q. ISL is Cisco proprietary, while 802.1Q uses the IEEE defined standard for trunking between switches.

To configure the 802.1Q standard, the keyword "dot1q" is used in Cisco switches.

Incorrect Answers:
A, B, D. These are not valid options in a Cisco switch.

C. ISL is a Cisco proprietary method for setting up trunks, and will only work between Cisco switches.

第8题:

交换机命令switch(config)# vtp prLming的作用是______。

A.指定交换机的工作模式

B.启用VTP静态修剪

C.指定VTP域名

D.启用VTP动态修剪


正确答案:D
解析:在默认情况下,所有交换机通过中继链路连接在一起,如果VLAN中的任何设备发出一个广播包、组播包,或者一个未知的单播数据包,交换机都会将其洪泛到所有与源VLAN端口相关的各个输出端口上,包括中继端口。在很多情况下,这种洪泛转发是必要的,特别是在VLAN跨越多个交换机的情况下。然而,如果相邻的交换机上不存在源VLAN的活动端口,则这种洪泛发送的数据包是无用的。
  虽然单个广播包尚不足以引起人大的问题,但是如果这是PC-A发出的10Mb/s的组播视频流,那么中继链路的吞吐率就会遇到严重的挑战。
  为了解决这个问题,可以使用静态或动态修剪方法。所谓静态修剪,就是手工剪掉中继链路上不活动的VLAN。但是,手工修剪方式容易出错。
  VTP动态修剪允许交换机从中继连接上动态地剪掉不活动的VLAN,使得所有共享的VLAN都是活动的。例如,交换机A告诉交换机B,它有两个活动的VLAN1和VLAN2,而交换机B告诉交换机A,它只有一个活动的VLAN1,于是,它们就共享这样的事实:VLAN2在它们之间的中继链路上是不活动的,应该从中继链路的配置中剪掉。
  这样做的好处是显而易见的,如果以后在交换机B上添加了VLAN 2的成员,交换机B就会通知交换机A,它有了一个新的活动的VLAN2,于是,两个交换机动态地把VLAN2添加到它们之问的中继链路配置中,如下图所示。
  VTP动态修剪的缺点是它要求在VTP域中的所有交换机都必须配置成服务器。由于交换机在服务器模式下工作时可以改变VLAN配置,也可以接受VLAN配置的改变,所以当多个管理员在多个服务器上同时配置VLAN时将会出现灾难性的后果。
  交换机命令switch(conrig)# vtp pruning的作用是启用VTP动态修剪。

第9题:

What are two characteristics of a switch that is configured as a VTP client?()

A.if a switch that is configured to operate in client mode cannot access a VTP server,then the switch reverts to transparent mode.

B.The local vlan configuration is updated only when an update that has a higher configuration revision number is received.

C.Vtp advertisements are not forwarded to neighboring switches that are configured in vtp transparent mode.

D.When switches in vtp client mode are rebooted,they send a vtp advertisement request to the vtp servers.

E.Vtp client is the default vtp mode

F.On switches that are configured to operate in client mode ,vlans can be created,deleted,or renamed locally
