In Huawei CloudFabric architecture, iMaster NCE-Fabric acts as the central network controller and automation platform that directly integrates with server virtualization platforms such as FusionSphere, VMware vCenter, and OpenStack . This integration enables automated network provisioning, policy enforcement, and dynamic resource orchestration between compute and network layers.

Through northbound APIs, iMaster NCE-Fabric communicates with virtualization platforms to obtain tenant, VM, and network information. It then translates these requirements into fabric configurations, such as VXLAN, EVPN, and underlay routing policies. This tight integration is essential for automated service deployment and end-to-end orchestration , which is a core capability in Huawei’s CloudFabric solution.

On the other hand, iMaster NCE-FabricInsight is focused on intelligent O & M, monitoring, and analytics . It provides telemetry-based visibility, fault detection, and performance optimization, but it does not directly connect to or integrate with virtualization platforms for service provisioning.

Therefore, the correct answer is iMaster NCE-Fabric , as it is the component responsible for connecting to server virtualization systems and enabling automation.

In Huawei Cloud Stack (HCS) architecture, ManageOne serves as the unified cloud management platform , responsible for end-to-end orchestration, service provisioning, and lifecycle management across compute, storage, and network resources. It provides a centralized portal for administrators and tenants, enabling automated deployment and O & M of cloud services.

FusionSphere is Huawei’s virtualization platform (similar to OpenStack + hypervisor integration) and operates at the resource layer, not as the top-level management system. Hypervisor and Virtual Machine Monitor (VMM) are components of the virtualization layer that manage virtual machines on physical servers, but they lack cloud-wide orchestration capabilities.

From a Huawei CloudFabric perspective, ManageOne integrates with controllers like iMaster NCE-Fabric to automate network provisioning, enabling seamless underlay and overlay configuration. It supports multi-data-center management, self-service portals, and policy-driven automation, which are essential for modern cloud data center operations.

Therefore, ManageOne is the correct answer as the cloud management platform in HCS.

In Huawei CloudFabric architecture, the underlay network is the physical IP fabric, while the overlay network is a logical network built on top of it using technologies like VXLAN and BGP EVPN .

Option A is false because the overlay network does not require bare optical fibers . It operates independently of the physical medium and can run over any IP-based underlay (Ethernet, optical, etc.). The overlay abstracts the physical infrastructure.

Option B is correct : the underlay network is transparent to endpoints (servers, firewalls, routers). These devices only interact with the overlay and are unaware of the underlying transport.

Option C is correct : the overlay has its own forwarding plane (VXLAN encapsulation) and control plane (BGP EVPN) , enabling scalable and automated network virtualization.

Option D is correct : the overlay is a logical network built over the underlay , providing tenant isolation and flexible service deployment.

Huawei best practices emphasize decoupling overlay from underlay , ensuring flexibility, scalability, and simplified operations.

Therefore, the correct answer is A .

Huawei’s AI Fabric solution is designed to build a unified, intelligent lossless data center network by integrating traditionally separate network infrastructures into a single converged Ethernet-based fabric.

The three integrated networks are:

Computing network (C): Handles east-west traffic between compute nodes (e.g., AI training clusters, GPU servers).

Storage network (B): Supports high-throughput, low-latency storage access (e.g., distributed storage systems like HDFS or Ceph).

Ethernet network (D): Provides the underlying IP-based transport, enabling unified connectivity and scalability.

Traditionally, InfiniBand (IB) networks were used for high-performance computing due to their low latency and RDMA capabilities. However, Huawei AI Fabric replaces IB with lossless Ethernet (RoCE-based) solutions, allowing all services (compute + storage + management) to run over a single Ethernet fabric .

This convergence reduces:

Network complexity

Capital and operational costs

Management overhead

While improving:

Resource utilization

Scalability

Automation

Therefore, the correct three networks are Storage, Computing, and Ethernet , making B, C, and D correct .
