Huawei Updated H19-402_V1.0 Exam Questions and Answers by griffin

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.

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 .

In Huawei CloudFabric and cloud platform architectures (such as those integrated with ManageOne and OpenStack ), the concept of a tenant is used to logically isolate resources such as network, compute, and storage . It is correct that one department can be treated as a tenant , and an enterprise can have multiple tenants representing different departments or business units.

However, the statement is false because it incorrectly claims that the entire enterprise data center can be managed by one tenant administrator . In Huawei’s design:

Each tenant has its own administrator , responsible only for that tenant’s resources.

A higher-level role, such as a cloud administrator or system administrator , manages the entire data center infrastructure across all tenants.

This separation ensures:

Multi-tenancy isolation

Security and access control

Clear responsibility boundaries

Huawei emphasizes role-based access control (RBAC) , where tenant admins cannot manage resources belonging to other tenants or the entire infrastructure.

Therefore, the correct answer is FALSE .

Comprehensive and Detailed 150 to 200 words of Explanation From Huawei data center:

After rechecking against Huawei’s own materials, the verified multi-select answer is B and D . Huawei documentation for Elastic Load Balance, which is the load-balancing architecture referenced in Huawei cloud/data center designs, states that for Layer 4 traffic using TCP/UDP , incoming traffic is routed only through the LVS cluster . For Layer 7 traffic using HTTP/HTTPS , incoming traffic is routed first to the LVS cluster and then to the Nginx cluster before reaching backend servers. That means Huawei explicitly uses LVS for L4 load balancing and Nginx together with LVS for L7 load balancing.

By contrast, IP ECMP is a Layer 3 equal-cost forwarding/load-sharing mechanism, not an L4-L7 service load balancer in Huawei’s CloudFabric context. Huawei’s ECMP documentation discusses route-based traffic distribution in the IP layer, which is fundamentally different from application/service load balancing.
