H19-402_V1.0 Practice Questions

Huawei iMaster NCE-Fabric ZTP (Zero Touch Provisioning) is designed to enable automated, fast, and error-free deployment of data center network devices, significantly reducing manual configuration efforts.

All listed options are valid characteristics:

Plug-and-play (A): Devices can automatically obtain configurations once powered on and connected to the network, requiring minimal manual intervention.

Visualized device onboarding (B): The controller provides a graphical interface to monitor onboarding progress, topology, and device status, improving deployment visibility.

Link verification (C): ZTP includes automatic cabling and link detection/verification , ensuring correct physical connections before service provisioning.

Batch device onboarding (D): Multiple devices can be onboarded simultaneously, enabling large-scale data center deployment with high efficiency.

Huawei emphasizes ZTP as a key capability in CloudFabric for:

Rapid service rollout

Reduced human error

Standardized deployment

Simplified O & M

This aligns with Huawei’s goal of achieving fully automated and intelligent data center network provisioning .

Therefore, the correct answers are A, B, C, and D .

In Huawei CloudFabric’s cloud-network integration scenario , the SDN controller iMaster NCE-Fabric must interconnect with multiple key components to enable end-to-end automation and orchestration .

Cloud platform (A): Platforms such as OpenStack or ManageOne integrate with iMaster NCE-Fabric via northbound APIs. This allows automatic network provisioning when tenants create networks, VMs, or services.

VMM (C - Virtual Machine Manager): Integration with virtualization platforms (e.g., VMware vCenter, FusionSphere) enables dynamic VM-aware networking, including automatic port and policy configuration.

Physical switch (D): These are the core devices controlled by iMaster NCE-Fabric. The controller pushes configurations (VXLAN, EVPN, routing) to build the underlay and overlay fabric.

Firewall (B) is typically integrated as a service device (VAS) but is not directly required to interconnect with the controller in all scenarios. It is usually inserted via service chaining rather than direct control-plane integration.

Huawei emphasizes controller-based automation , where iMaster NCE-Fabric coordinates between cloud platforms, virtualization systems, and physical network devices.

Therefore, the correct answers are A, C, and D .

In Huawei CloudFabric Solution, health check and intelligent O & M are performed across multiple key dimensions to ensure stable, secure, and efficient network operations. These dimensions provide a comprehensive view of the data center network’s health.

Capacity (A): Evaluates resource utilization such as bandwidth, device capacity, and scalability limits to prevent bottlenecks.

Status (B): Monitors the operational state of devices, links, and services (up/down, faults, alarms).

Connectivity (D): Verifies end-to-end network reachability, ensuring that services and tenants can communicate properly across the fabric.

Security policy (E): Checks correctness and consistency of policies such as ACLs, segmentation, and service chaining rules.

Performance (F): Measures latency, packet loss, throughput, and congestion, which are critical in modern workloads like AI and storage.

VM (C) is not considered a core health check dimension at the network level. It belongs more to the compute/virtualization domain rather than network O & M.

Huawei iMaster NCE-FabricInsight uses these dimensions to provide proactive fault detection, root cause analysis, and optimization recommendations , ensuring intelligent lifecycle management of the data center network.
