Huawei Updated H35-211_V2.5 Exam Questions and Answers by arianna

In NGN architectures, services (voice, video, data) converge over a packet-based backbone. The core switching layer provides the unified transport using IP/MPLS and related QoS mechanisms, delivering high reliability and large-capacity switching for all upper-layer services. The control and management layers orchestrate services, while the edge/access layer aggregates users—but the packet-based integrated transmission platform itself is the role of the core.

The ONT details pane in eSight displays access-port attributes (admin/state, type), Ethernet rate/speed/duplex, and PON optical module telemetry such as temperature and Tx/Rx optical power for condition monitoring and troubleshooting.

Huawei QoS describes PQ (Priority Queuing) as the strict-priority scheduler ensuring that high-priority queues are served first before lower-priority queues. WRR/DRR/RR are weighted or round-robin modes intended for fair sharing and do not guarantee strict preemption for latency-sensitive traffic. Therefore, PQ is selected for higher-priority services (e.g., voice, control).
