Huawei HCIA-Datacom V2.0 Sample Questions:
On an intelligent computing data center network, the lossless network technology _____ is deployed to instruct the sender to stop sending packets when network congestion is about to occur, ensuring zero packet loss on the network. (Enter the acronym in uppercase.)
Reveal Solution Discussion 0Correct Answer:
PFC
Explanation:
The acronym in the source file is mistyped as PCF. The correct intelligent lossless Ethernet technology is PFC, which stands for Priority-based Flow Control. PFC extends Ethernet flow control by applying pause behavior to selected traffic priorities rather than stopping all traffic on an interface. When a downstream device detects that a lossless priority queue is approaching congestion, it can send a priority-specific pause indication to the upstream sender. The upstream device temporarily stops transmitting traffic for that priority, preventing the downstream buffer from overflowing and thereby supporting zero-packet-loss behavior for the protected traffic class. This capability is important in intelligent computing and data center fabrics carrying storage or high-performance computing workloads that are sensitive to packet loss. Huawei describes PFC as a foundational technology for intelligent lossless networks, often used together with congestion-management mechanisms such as ECN and related optimization features. Therefore, the blank must be filled with PFC in uppercase. The original answer PCF should be corrected to PFC.
