Which service does the ERX Edge Router support with a virtual router?() A.voice over IPB.wholesale servicesC.IP quality of serviceD.SNMP management
When designing a converged network, which measures can be taken at the building access layer to help eliminate latency and ensure end－to－end quality of service can be maintained? () A. rate limit voice trafficB. configure spanning-tree for fast link convergenceC. isolate voice traffic on separate VLANsD. classify and mark traffic close to the source
Choose the false statement concerning the use of CiscoWorks Internetwork Performance Monitor (IPM) in a Teleworker deployment.（）A、IPM should not be run on a production network. B、IPM helps verify if a Service Provider is meeting the Service Level Agreement. C、IPM contains a database that can store data on latency, jitter, and drops of voice packets over a period of weeks or months. D、The QoS service policy should contain an allocation of sufficient bandwidth in the priority queue (LLQ) for both the SAA probe simulating a voice call and the voice call. If not, voice quality will suffer.
What can be used to maintain the voice quality on a link by limiting the number of calls that can be active at any given time？（）A、 Call Management Link AgentB、 Traffic policingC、 Call Admission ControlD、 QoS Link Congestion ManagementE、 Oversubscription Link Detection

Which two statements are true about Voice over IP （VoIP） packet delivery in a digital infrastructure？ （）A、 Packets can arrive out of order.B、 Packets must take the same path to the destination.C、 Once packets are received at the destination router， the router performs sampling to ensure the quality of the voice traffic.D、 Packets can experience varying delays across the network.E、 Packets containing voice samples are sequentially numbered by default， allowing for reordering upon arrival at the terminal router along the path.

Voice quality is bad due to high delay and jitter on a link. Which two actions will improve the quality of voice calls？（）A、Increase the queue size of the voice class.B、Guarantee bandwidth during congestion to the voice class with a bandwidth command.C、Increase the tx-ring of the egress interface.D、Implement LLQ for the voice class.E、Decrease the rx-ring of the egress interface.F、Decrease the queue size of the voice class.
Which two statements are true about the function of CAC？（）A、CAC provides guaranteed voice quality on a link.B、CAC artificially limits the number of concurrent voice calls.C、CAC is used to control the amount of bandwidth that is taken by a call on a link.D、CAC prevents oversubscription of WAN resources that is caused by too much voice traffic.E、CAC allows an unlimited number of voice calls while severely restricting，if necessary，other forms of traffic.F、CAC solves voice congestion problems by using QoS to give priority to UDP traffic.
A network administrator has been receiving work orders about poor voice quality crossing a branch T1. The cause is determined to be users running high bandwidth file sharing applications across the T1 sending large packets delaying the smaller voice streams.
