Explanation:
The verified answer is the displayed drag-and-drop mapping. QoS congestion management controls how packets are queued and scheduled when an interface is congested. Terms such as FIFO, priority queuing, weighted fair queuing, class-based WFQ, and low-latency queuing describe different ways to decide which packets leave first. Cisco CCNA 200-301 v1.1 places this skill in IP Services, where the exam expects a working understanding of how the feature behaves on real Cisco networks, not just a memorized command.
Congestion avoidance, classification, and marking are related QoS functions, but they are not the same as queue scheduling during congestion. In production, this distinction matters because a misapplied command or design choice usually creates an outage, a security gap, or unnecessary troubleshooting noise. The correct choice matches the control-plane, data-plane, wireless, security, or services behaviour described in the scenario and should be preferred over options that merely sound related.
