A. Resources are pooled between zones to avoid uneven resource distribution.
B. The logical two-layer architecture has a high oversubscription ratio.
C. The flattened network features redundancy, reliability, and high throughput, facilitating east-west network capacity expansion.
D. Each leaf node is connected to one or two spine nodes to enable communication between all types of nodes connected to the network.
Answer:<\/strong> B
Explanation<\/strong>:
Huawei\u2019s data center design guidelines emphasize that spine-leaf architecture is a flattened, two-layer fabric designed to overcome the limitations of traditional three-tier networks. One of its key advantages is low and predictable oversubscription ratios, achieved through equal-cost multi-path (ECMP) forwarding and uniform link distribution.
Option A is correct as an advantage because spine-leaf enables resource pooling across zones, eliminating isolated silos and improving utilization.
Option C is also a core benefit: the architecture provides high reliability, redundancy, and scalable east-west traffic capacity, which is critical for cloud and distributed applications.
Option D reflects the fundamental design principle where each leaf connects to multiple spine switches, ensuring full-mesh reachability and consistent latency.
However, Option B states that the architecture has a high oversubscription ratio, which contradicts Huawei best practices. In fact, spine-leaf is specifically designed to minimize oversubscription, ensuring balanced traffic and predictable performance.
Therefore, B is not an advantage, making it the correct answer.<\/p>\n\n\n\n
What are the three networks?
A. IB network
B. Storage network
C. Computing network
D. Ethernet network
Answer:<\/strong> B C D
Explanation:<\/strong>
Huawei\u2019s 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.<\/p>\n\n\n\n
A. Cloud platform
B. Firewall
C. VMM
D. Physical switch
Answer:<\/strong> A C D
Explanation:<\/strong>
In Huawei CloudFabric\u2019s 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.<\/p>\n\n\n\n
A. Private cloud (converged resource pool deployment and data center integration)
B. Hosting services in traditional IDCs
C. Public cloud service (IaaS\/PaaS\/SaaS)
D. Network NFV cloud (network cloud and SDN + NFV)
Answer:<\/strong> A B C D
Explanation:<\/strong>
Huawei data center design documents clearly state that overlay networks (typically based on VXLAN EVPN) are highly versatile and support multiple application scenarios across modern and traditional environments.
In private cloud scenarios, overlay networks enable resource pooling and seamless data center interconnection, allowing flexible workload migration and multi-tenant isolation. For traditional IDC hosting services, overlays provide improved scalability and tenant isolation compared to VLAN-based designs, making them suitable for legacy-to-cloud evolution.
In public cloud environments (IaaS\/PaaS\/SaaS), overlay networks are essential for large-scale multi-tenancy, enabling logical network segmentation, automation, and elastic service provisioning. Similarly, in NFV cloud scenarios, overlays integrate with SDN and NFV architectures to support virtualized network functions, service chaining, and dynamic service deployment.
Huawei CloudFabric emphasizes that overlay technology is not limited to a single use case but is a foundational technology across all modern data center architectures. Therefore, all listed options are valid application scenarios.<\/p>\n\n\n\n
A. An M-LAG can be established between two devices of different types.
B. If the access device is single-homed to the M-LAG, the M-LAG does not deliver the unidirectional isolation configuration of the corresponding M-LAG member interface.
C. A peer-link is a direct link and must be configured with link aggregation.
D. An interface configured as a peer-link interface cannot be configured with any other service.
Answer:<\/strong> A
Explanation:<\/strong>
In Huawei M-LAG design, strict requirements ensure stability and consistency between the two participating devices.
Option A is false because M-LAG must be established between devices of the same type and model (or at least fully compatible models). This ensures consistent forwarding behavior, synchronization of MAC \/ARP tables, and proper operation of the peer-link and keepalive mechanisms. Using different device types is not supported and may lead to instability.
Option B is correct: unidirectional isolation is relevant only for dual-homed scenarios. If a device is single-homed, this mechanism is not applied.
Option C is correct: the peer-link is a critical connection between M-LAG peers and is typically configured as an Eth-Trunk (link aggregation) to ensure high bandwidth and redundancy.
Option D is also correct: peer-link interfaces are dedicated and cannot be used for other services, ensuring reliable synchronization and control-plane communication.
Huawei best practices emphasize homogeneous device deployment for M-LAG to guarantee predictable and stable operation.<\/p>\n\n\n\nFrequently Asked Questions about H19-402_V1.0 Practice Tests<\/h2>\n\n\n\n
