第2题:
You are the network administrator of an enterprise with a main site and multiple remote sites. Your networkcarries both VOIP and data traffic. You agree with your service provider to classify VOIP and data trafficaccording to the different service RFCs. How can your data and VOIP traffic be marked?()
第3题:
Which two statements correctly describe a Cisco WLC configuration of Wireless > QoS > Profiles >Wired_QoS_Profiles for an implementation of DSCP or CoS deployment?()
第4题:
What is the typical marked DSCP value for a voice signaling packet in VoIP technology?()
第5题:
With the DSCP value fo "101110", what does the "11" in bits 1 and 2 indicate ?()
第6题:
You are the network administrator of an enterprise company that just deployed a global IP telephony environment. In order to guarantee good voice quality, you asked your provider to implement QoS on the CE routers of your MPLS network. On your LAN, you have also deployed QoS. Users, however, keep complaining about bad voice quality, and the provider does not see matches on the DSCP values that you have asked him to match upon. What is most likely the problem?()
第7题:
BE流的DSCP编码值为()。
第8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9题:
source IP address and the protocol (such as SSL,HTTPS,SSH)
the packet Time to Live and the source IP address
type of service header and DSCP value
destination IP address
第10题:
第11题:
BE
AF41
AF21
EF
AF31
第12题:
IP precedence
type of service (ToS)
class of service (CoS)
differentiated services code point (DSCP)
第13题:
How many bits represented in DSCP?
第14题:
End-to-end QoS is maintained in the Cisco WLAN deployment model by utilizing what parameter in lieu of 802.1p?()
第15题:
You are the network administrator of an enterprise with a main site and multiple remote sites. Your network carries both VOIP and data traffic. You agree with your service provider to classify VOIP and data traffic according to the different service RFCs. How can your data and VOIP traffic be marked?()
第16题:
以下关于DSCP和IP Precedence的比较的说法正确的是()。
第17题:
What is the typical marked DSCP value for a voice media packet in Voice over IP technology?()
第18题:
Your Cisco network currently runs OSPF and you have a need to policy-route some specific traffic,regardless of what the routing table shows. Which one of these options would enable you to policy-route the traffic?()
第19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.
