第5题:
You are working with CIS .com. who has identified the following IP applications on their network: IP voice and voice signaling, streaming video, PeopleSoft, Microsoft SQL, e-mail, and Internet traffic. If the voice traffic was classified as EF and AF31, the e-mail was classified as AF11, and the Internet traffic was classified as DSCP 0, how would the transactional traffic represented as PeopleSoft and Microsoft SQL be classified?()
第6题:
BE流的DSCP编码值为()。
第7题:
79xx IP phones do not automatically mark voice packets with non-zero DSCP values.
79xx IP phones do not mark protocol packets such as DHCP, DNS, or TFTP with non-zero DSCP values.
79xx IP phones do not mark voice packets with optimal DSCP values.
79xx IP phones use a custom protocol to communicate CDP information to the switch.
第8题:
用TOS字段的前6个比特(高6比特)来表示不同的业务类型,称为DSCP
可以使用DSCP将流量分成32类
每个DSCP值对应一个BA(Behavior AggregatE.,然后可以对每一个BA指定一种PHB
可以使用某些Qos机制;来实现这个PHB
第9题:
data marked with DSCP AF21,VOIP marked with DSCP EF
data marked with DSCP AF51,VOIP marked with DSCP EF
data marked with the DE-bit. VOIP marked with the CLP-bit
data marked with DSCP EF,VOIP marked with DSCP AF31
data marked with IP precedence 5,VOIP marked with DSCP EF
第10题:
第11题:
data marked with DSCP AF21,VOIP marked with DSCP EF
data marked with DSCP AF51,VOIP marked with DSCP EF
data marked with the DE-bit,VOIP marked with the CLP-bit
data marked with DSCP EF,VOIP marked with DSCP AF31

第12题:
第13题:
Which two IntServ functions are required on a router?()
第14题:
Which one of these class maps was configured to match traffic for CS5?()
第15题:
以下关于DSCP和IP Precedence的比较的说法正确的是()。
第16题:
QOS Configuration配置中不包括?()
第17题:
What is one of the reasons that custom QoS ACLs are recommended over automatic QoS when configuring ports on a Catalyst 6500 for use with IP phones?()
第18题:
BE
AF41
AF21
EF
AF31
第19题:
DSCP可以兼容IP Precedence
因为DSCP扩展了用于流分类的比特位,所以不能简单的映射到IP Precedence里面去
DSCP包括6比特而IP Precedence包括3比特
因为仅仅可以使用RFC定义的DSCP,DSCP在使用上比IP Precedence更受限制
第20题:
A PVC bundle will not come up unless all the precedence, DSCP, and EXP levels are configured in thebundle.
A PVC bundle can perform precedence and DSCP matching at the same time
A PVC bundle may contain no more than sixteen PVCs
A PVC can be in only one PVC bundle
A PVC bundle cannot perform precedence and DSCP matching at the same time.
A PVC bundle may contain no more than eight PVCs.
第21题:
PTN根据基站上报的DSCP进行速率QoS映射
PTN设备根据IP报文的IP DSCP和VLAN PRI映射到MPLS TC
基站根据QCI映射到IP报文的IP DSCP和VLAN PRI
基站根据UE发起的期望速率上报DSCP
第22题:
第23题:
It must always be set on all QoS profile types because this sets the type of markings as either CoS or DSCP.
It is optional if the Cisco WLC attached switch operates on a trust DSCP model.
It must be set if the Cisco WLC attached switch operates on a trust CoS model.
It sets the EDCF queue used for the radio-transmitted frames.
