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.

C) The RED technology can reduce the jitter during packet transmission.
D) Tail drop causes global TCP synchronization and reduces bandwidth usage.

C) seems off, RED is more about managing queues than jitter.

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?
