HuaweiiMaster NCEis acentralized network management and control systemforSDN-capableandtraditionaldevices.

(A) True – SDN control via NETCONF/YANG:

iMaster NCE usesNETCONF(based on theYANG model) to manage and controlSDN-enableddevices, automating configuration and policy enforcement.

(B) True – SNMP for traditional devices:

Traditional network devices (non-SDN) are managed throughSNMP (Simple Network Management Protocol), which provides device monitoring and basic configuration.

(C) False – No direct control through CU (Control Unit):

Huawei does not define aCUas an independent management entity in iMaster NCE. Instead, SDN-capable devices are controlled viaNETCONF/YANG, while traditional devices rely onSNMP.

Huawei's vision for the datacom industry is indeed "IP on everything," reflecting its commitment to building ubiquitous, intelligent, and converged IP networks. This vision emphasizes the integration of IP technologies into all aspects of communication, including data centers, campuses, and wide-area networks, to support digital transformation and innovation.

The statement is therefore TRUE .

Huawei's CloudWAN solutions target various railway services and market opportunities. Below is an analysis of each option:

Integrated information network : This refers to the unified network infrastructure that integrates multiple railway systems, such as passenger information, ticketing, and security. It is a key focus area for Huawei routers.

Vehicle-ground communication network : This involves communication between trains and ground stations, enabling real-time monitoring, diagnostics, and control. It is a critical railway service supported by Huawei routers.

Interconnection load balancing between backbone clouds : This is more relevant to cloud data center interconnections rather than railway-specific services. It is not a primary focus for railway services.

Railway signal bearer network : This refers to the network that carries signaling and control information for safe train operations. It is a core railway service supported by Huawei routers.

Thus, the correct answer is C , as interconnection load balancing between backbone clouds is not directly related to railway services.
