NEW QUESTION 17
Which of the following is not a requirement of AI computing on networks?

Traffic control in incast scenarios

Fast and efficient load balancing

Quick congestion control

High-performance computing (HPC)

Huawei’s Intelligent Lossless Data Center Network is specifically designed to meet the stringent requirements of AI computing workloads , which generate massive east-west traffic and exhibit bursty communication patterns such as incast scenarios . Therefore, traffic control in incast scenarios (A) is a critical requirement to prevent buffer overflow and packet loss.
Fast and efficient load balancing (B) is also essential, as AI training jobs rely on distributed computing across multiple nodes. Technologies like ECMP and flowlet-based load balancing ensure even traffic distribution and optimal link utilization.
Quick congestion control (C) is another key requirement. Mechanisms such as PFC (Priority Flow Control) and ECN (Explicit Congestion Notification) are used in Huawei CloudFabric to achieve near lossless transmission, which is vital for RDMA-based AI workloads.
However, High-performance computing (HPC) (D) is not a network requirement-it is an application and compute domain concept . While AI workloads may run on HPC systems, HPC itself is not a characteristic or requirement of the network.
Therefore, the correct answer is D .

NEW QUESTION 18

2 servers + 1 disk array + 1 switch

2 servers + 2 disk arrays + 3 switches

1 server + 1 disk array + 2 switches

None of the above is correct

NEW QUESTION 22

True

False

NEW QUESTION 28
In UPS5000 configuration, the power supply reliability level cannot be selected.

True

False

NEW QUESTION 29
Which of the following statements is false about M-LAG?

An M-LAG can be established between two devices of different types.

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.

A peer-link is a direct link and must be configured with link aggregation.

An interface configured as a peer-link interface cannot be configured with any other service.

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.

Inlet and outlet

Up-line in and down-line out

Lower inlet and upper outlet

Inlet and outlet

NEW QUESTION 36
Which of the following are characteristics of distributed VXLAN gateways?

A distributed VXLAN gateway (leaf node) only needs to learn the ARP entries of servers connected to it, whereas a centralized Layer 3 VXLAN gateway needs to learn the ARP entries of all servers on a network. Therefore, the number of ARP entries supported is no longer a bottleneck on distributed VXLAN gateways, and the network scalability is improved.

Forwarding paths are not optimal. Inter-subnet Layer 3 traffic between devices connected to the same gateway in a data center must be transmitted to a unified Layer 3 gateway for forwarding.

A leaf node can function as both a Layer 2 VXLAN gateway and a Layer 3 VXLAN gateway, supporting flexible deployment.

The number of ARP entries supported is a bottleneck. A single Layer 3 gateway is used. For tenants whose traffic is forwarded by the Layer 3 gateway, ARP entries must be generated for the tenants on the Layer 3 gateway, but only a limited number of ARP entries are allowed by the Layer 3 gateway, which impedes data center network expansion.

In Huawei CloudFabric VXLAN design, distributed gateway architecture is a key enhancement over traditional centralized gateway models, especially for large-scale data centers.
Option A is correct because distributed gateways (typically deployed on leaf nodes) only maintain local ARP
/MAC entries for directly connected hosts. This significantly reduces ARP table pressure compared to centralized gateways, where a single device must learn all entries. This improves scalability and performance , which is critical in multi-tenant environments.
Option C is also correct as Huawei leaf switches can simultaneously act as Layer 2 VXLAN gateways (bridging) and Layer 3 VXLAN gateways (routing) . This enables distributed inter-subnet routing directly at the access layer, reducing latency and improving east-west traffic efficiency.
Option B is incorrect because it describes a limitation of centralized gateways , where traffic must traverse a central node, leading to suboptimal paths. Distributed gateways eliminate this issue.
Option D is also incorrect as it again describes centralized gateway constraints, not distributed ones.
Thus, distributed VXLAN gateways provide better scalability, optimal forwarding paths, and flexible deployment , making A and C correct .
