Huawei H35-211_V2.5 Exam With Confidence Using Practice Dumps

According to IEEE 802.3av wavelength planning adopted by Huawei 10G-EPON, downstream uses 1577 nm and 10G upstream uses 1270 nm. In asymmetric coexistence, 1G-EPON upstream uses 1310 nm, but for 10G-EPON upstream specifically the wavelength is 1270 nm. Therefore the correct upstream wavelength for 10G-EPON is 1270 nm.

Huawei OLTs support Eth-Trunk (link aggregation) with two standard modes: Static aggregation and Dynamic aggregation (LACP). These provide bandwidth expansion and redundancy on NNI uplinks. “Automatic” is not a defined mode; and “manual” is not used as a separate mode name in OLT Eth-Trunk configuration.

Huawei GPON implements hierarchical traffic control. CAR (Committed Access Rate) can be applied at multiple layers: GEM-port level (GEM-CAR), per-flow (Flow-CAR), and T-CONT level (T-CONT-CAR) for upstream bandwidth policing/shaping and guaranteeing QoS. GEM mapping is a classification/association mechanism (service → GEM/T-CONT) rather than a traffic-control action, so it is not a CAR measure.
