A customer has an existing WAN circuit with a capacity of 10 Mbps. The circuit has 6 Mbps of various user traffic and 5 Mbps of real-time audio traffic on average. Which two measures could be taken to avoid loss of real time traffic? (Choose two.)
A. Police the traffic to 3.3 Mbps and allow excess traffic to be remarked to the default queue.
B. Configure congestion avoidance mechanism WRED within the priority queue.
C. Ensure that real time traffic is prioritized over other traffic.
D. Police the traffic to 5 Mbps and allow excess traffic to be remarked to the default queue.
E. Increase the WAN circuit bandwidth.
CD
police the real-time traffic is not the correct answer, it will be if shape, not police.
Even shaping should not be used for real time traffic, as latency may increase as packets might be queued for a while before being sent.
WRED should not be used with PQ, so it looks like C and E to me (maybe there’s an issue with wording in the question, but policing doesn’t seem to make much sense here).
