Скачать или смотреть iQCN Function Explained Intelligent Congestion Control in Data Center Networks HCIE H12 921 MCQ

In this video, we explain how the iQCN (Intelligent Quantized Congestion Notification) function works in Huawei data center switches.
✅ Correct Answer: A - TRUE

The iQCN mechanism intelligently detects congestion by analyzing CNP (Congestion Notification Packet) intervals. When a NIC fails to reduce its rate quickly enough—or worse, increases it—the switch proactively sends additional CNPs to slow down traffic from the RP (Reaction Point). This proactive strategy helps maintain low latency and optimize throughput in high-performance, lossless data center networks.

Master these kinds of insights to crush your HCIE-Data Center Network (H12-921) exam and understand the next-gen congestion control protocols shaping modern data centers.
