单选题Refer to the exhibit. With an IPSec tunnel established between remote Router A and head-end router B, with Compressed Real-Time Protocol (cRTP) configured on the serial interface of Router A, what impact will the cRTP configuration have on the Voice over IP packets flowing through the IPSec tunnel from a Cisco 7960 IP phone?（）A Twenty bytes of header will be replaced with five bytes. B If the IPSec transform set includes Authentication Header, the receiving IPSec peer will discard the packets.

多选题Which two statements about WRED are true？ （）AWRED can selectively discard lower priority traffic when the interface becomes congested and can provide differentiated performance characteristics for different classes of service.BResource Reservation Protocol （RSVP） and WRED cannot be configured on the same interface.CWRED will throttle back voice traffic only as a last resort.DIf the average queue length is greater than the minimum threshold but less than the maximum threshold， then based on the drop probability， WRED will either queue the packet or perform a random drop.EWRED statistically drops more packets from low-bandwidth users than high-bandwidth users. Therefore， traffic sources that generate the least traffic are more likely to be slowed down than traffic sources that generate the most traffic.FWRED treats non-IP traffic as precedence 4.

单选题Choose the false statement concerning the use of CiscoWorks Internetwork Performance Monitor (IPM) in a Teleworker deployment.（）AIPM should not be run on a production network. BIPM helps verify if a Service Provider is meeting the Service Level Agreement. CIPM contains a database that can store data on latency, jitter, and drops of voice packets over a period of weeks or months. DThe 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.
