Exam 400-007 topic 1 question 71 discussion

To mitigate this issue, traffic shaping (Option D) could be a suitable technology. Traffic shaping, also known as packet shaping, is a congestion management method that regulates network data transfer to ensure a smooth flow of traffic, prevent bottlenecks, and reduce latency. It can help ensure that available bandwidth is shared fairly and can prioritize traffic to critical services like your DaaS solution. Please note that while traffic policing (Option A) can also help manage bandwidth, it does so by dropping packets or reducing the speed of packet transmission when traffic exceeds a certain limit, which might not be ideal for your situation. Weighted Random Early Detection (WRED, Option B) and tail drop (Option C) are mechanisms for managing network congestion, but they do this by dropping packets when certain conditions are met, which could lead to further disconnections. Remember to consult with a network specialist or your service provider before making significant changes to your network configuration.

D - A CBWFQ Shaper with WRED applied to the default queue would be ideal, but we do not have that luxury of an answer. So D seems most sensible out of the choices available.

WRED is the same 'level' answer as traffic policing. Remote Desktop services are UDP by default (can switch to TCP though). So WRED and policing will influence OTHER traffic, not RD traffic. so basically i would prefer something like CBWQF for this task. But we have not such answer. no good answers. may be D. some cisco forums shows that ppl are using shaping for traffic like RDP

(b) and (c) are congestion avoidance techniques that drop packets randomly after buffers is almost full and when is full, respectively. You cannot expect this to fix your problems. The only solution is to prioritize the traffic via (d)

B is correct. https://www.ciscopress.com/articles/article.asp?p=352991&seqNum=8 Different from RED, WRED can assign DaaS packets to have greater minimum thershold then have higher priority not to be dropped.

Shouldn't this be "D". Traffic Shaping does help with congestion and better bandwidth utilization over the WAN.
