Huawei H35-211_V2.5 Exam - Topic 5 Question 83 Discussion

Which of the following statements about congestion avoidance is incorrect?
A) To prevent high-priority packets from being discarded, the early drop threshold of high-priority packets is set to a smaller value.
B) Congestion avoidance is a traffic control mechanism that monitors the usage of network resources (such as queues or memory buffers) and discards packets when the system is congested to adjust the traffic and mitigate network overload.
C) The RED technology can reduce the jitter during packet transmission.
D) Tail drop causes global TCP synchronization and reduces bandwidth usage.

Yeah, B is solid. But C really stands out as wrong.

I'm leaning towards A being incorrect. Smaller thresholds can cause more drops.

True, but D is actually correct. It does lead to synchronization issues.

I feel like D is also questionable. Tail drop can mess up TCP flows.

I agree, C seems off. Jitter is more about timing, not just congestion.

True, but D is more about TCP behavior. C just doesn't fit with RED's purpose.

I feel like D is also misleading. Tail drop can cause issues, but not always reduce bandwidth.

I feel like congestion avoidance is all about monitoring and discarding packets, so option B seems accurate. But I'm a bit confused about the implications of tail drop.

I practiced a similar question where we discussed early drop thresholds, but I can't recall if they always need to be smaller for high-priority packets.

I think option D is the one that sounds incorrect. Tail drop causing global TCP synchronization seems counterintuitive to me.

I remember studying congestion control, but I'm not entirely sure about the specifics of RED technology. Did it really mention anything about jitter?
