考题
A branch router is configured with an egress QoS policy that was designed for a total number of 10 concurrent VOIP calls.Due to expansion， 15 VOIP calls are now running over the link， but after the 14th call was established， allcalls were affected and the voice quality was dramatically degraded.Assuming that there is enough bandwidth on the link for all of this traffic， which part of the QoS configuration should be updated due to the new traffic profile？（）A、Increase the shaping rate for the priority queue.B、Remove the policer applied on the priority queue.C、Remove the shaper applied on the priority queue.D、Increase the policing rate for the priority queue.

单选题Which statement is true about the Call Admission Control （CAC） feature in VoIP networks？（）A
CAC is used to allocate enough bandwidth for the number of calls that are allowed on the VoIP network.B
CAC is used to protect the quality of the voice calls by preventing call establishment if enough resources are not available on the network.C
CAC provides queuing mechanisms for voice calls if the packets exceed the configured or budgeted rate.D
In a VoIP network the CAC can be replaced with the LLQ QoS mechanism if it has been properly implemented.
