Which of the following statements are TRUE about iMaster NCE in terms of management and control?
Correct Answer:AB
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.

Which of the following statements is FALSE about Huawei AirEngine 5762-12SW?
Correct Answer:D
TheAirEngine 5762-12SWis a versatile Wi-Fi 6 AP designed for small and medium-sized enterprises. Key features include:
Flexible covers:The AP's cover can be customized to match the deployment environment. Leader AP functionality:It can manage up to eight Fit APs, simplifying network architecture. Maximum wireless rate:Supports up to2.975 Gbps, ensuring high-speed connectivity. However, the statement that it hastwo GE ports (one for uplink and one for downlink)isFALSE. The AirEngine 5762-12SW has onlyone GE portfor uplink, which limits its wired connectivity options.

The device's MAC address table specifications are greatly challenged by the rapidly increasing number of VMs. In order to solve this problem, we can use VXLAN with large- scale scalability. In a VXLAN scenario, which Huawei model can we propose?
Correct Answer:A
VXLAN (Virtual Extensible LAN) is a network virtualization technology that addresses the limitations of traditional VLANs and MAC address tables by enabling large-scale Layer 2 networks over Layer 3 infrastructure. It is particularly useful in data centers with a growing number of virtual machines (VMs).
Among the options provided:
CE6881 : This switch supports VXLAN and is designed for high-density data center environments. It provides excellent scalability and performance for VXLAN-based networks, making it the most suitable choice.
CE9860 : While this switch is a high-end model, it is primarily used for core or aggregation layers and may not be the best fit for VXLAN at the access layer.
CE6820 : This switch does not support VXLAN, making it unsuitable for the scenario. CE5882 : This is an older model and lacks the advanced features required for modern VXLAN deployments.
Thus, the correct answer is A , as the CE6881 is the most appropriate model for VXLAN scenarios.
