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, all calls 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.
Explanation:
The question works on the premise that there was no congestion on the link upto the 13th call.
When you please the 14th call there is congestion on the link.
When there is NO congestion the priority command is allowed to take as much bandwidth as
required. When there is congestion on the link the Priority command has to only use the
configured bandwidth.
Adding the 14th call caused congestion, which in turn made the priority command restrict the calls
to the configured value of 10 hence affect the quality of all calls.
