Huawei Hybrid Cable 2.0 integrates power lines and optical fibers into a single cable. It supports PoE+ (IEEE 802.3at) and extends the PoE+ power supply distance up to 600 meters without using additional power modules.

This feature is especially valuable for outdoor AP deployments where conventional Ethernet cabling distances are limited (typically up to 100 m). Hybrid Cable 2.0 simplifies cabling and reduces infrastructure costs in remote deployment scenarios.

Huawei’sintelligent cloud-network solutioninvolves the convergence of multiple product lines to buildNet5.5G-ready infrastructure:

A. CloudEngine: Core for data center and campus switching

B. NetEngine: High-performance routing platform for WAN and core network scenarios

C. HiSecEngine: Security product line for integrated and intelligent security services

D. AirEngine: Wireless access product line, including Wi-Fi 6/7

All four products are pillars in Huawei’s strategy to evolve towardubiquitous, intelligent, high-speed IP connectivityunderNet5.5G.

Huawei'sXinghe Multi-DC Network Solutionprovidesthree levels of ultra-high reliability:

A. Device-level high reliability: Achieves zero data loss through component redundancy

C. Network-level high reliability: Ensures no service disruption even during faults or upgrades

D. Link-level high reliability: Uses intelligent rerouting to prevent traffic interruption

B. High O&M reliability with hour-level fault locatingis not listed as a core reliability tier; Huawei emphasizesminute-level AI-driven fault detectioninstead.

M-LAG (Multi-Chassis Link Aggregation Group) is a technology that implements link aggregation across two or more independent physical devices (i.e., switches).

It enables downstream devices (such as servers or switches) to connect to two upstream devices as if they were one logical device.

This allows for:

Active-active forwarding (traffic load balancing)

Device-level redundancy (if one upstream device fails, the other continues forwarding traffic)

Eth-Trunk refers to link aggregation but generally within a single device.

Stack creates a logical switch from multiple physical switches, but it does not address inter-device aggregation in the same distributed manner as M-LAG.

LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol for device discovery and has no role in link aggregation.

HuaweiAirEngine APswith theleader AP featureare capable of managing Fit APs insmall-scale or branch networks. The supportedforwarding modesinclude:

A. Tunnel forwarding: Traffic is encapsulated and sent to the gateway (leader AP or AC)

B. Direct forwarding: Traffic exits directly at the AP to reduce latency

Bridge forwardingandroute forwardingare not standard forwarding modes in this context.Bridge modegenerally applies to Layer 2 switching, androute forwardingpertains to Layer 3 routers, not WLAN forwarding at the AP level.

Huawei’s High-Quality 10 Gbps Campus Network Solution is experience-centric and delivers upgrades in three key areas:

A. Wireless experience upgrade — Enhanced via intelligent radio calibration, Wi-Fi 7 AirEngine APs, and anti-interference tech.

C. O&M experience upgrade — Achieved through AI-based O&M and one map for unified visualization via iMaster NCE-Campus.

D. Application experience upgrade — Uses application awareness and traffic steering to ensure consistent performance.

B is incorrect: while O&M costs are optimized, this is not formally listed as one of the “three types of experience upgrade.”

Segment Routing (SR) introduces a source routing model where the source node defines the path that packets take through the network by imposing a list of segments (instructions).

SR is aligned with SDN principles — the network is programmable and flexible.

SR does NOT depend on LDP or RSVP. Instead, SR uses extensions to IGP (OSPF or IS-IS) or BGP to distribute segment information.

SR simplifies the control plane by reducing the number of protocols needed for label distribution.

SR can work with or without a controller — the controller enhances path computation but is not mandatory for basic SR operation.

Huawei’sAR6700Vis avirtual router(vCPE) that supports deployment onmainstream public clouds, including:

Huawei Cloud

Microsoft Azure

AWS Cloud

However, as per the latest support matrix,Baidu Cloudisnot listed as a supported platformfor AR6700V deployment.

Huawei's six comprehensive border security protection capabilities for SD-WAN or converged gateway routers typically include:

Built-in Firewall – Provides basic packet filtering and security zoning.

Remote URL Filtering – Uses cloud-based services to filter harmful websites.

Antivirus – Detects and blocks malicious files.

IPS (Intrusion Prevention System) – Detects and blocks known threats and attack signatures.

Application-level ACL – Allows granular control of applications beyond Layer 4 (e.g., blocking TikTok, WhatsApp, etc.).

Data leakage prevention (DLP) and behavioral analytics may also be included depending on the security license.

However, "Data encryption" is a broader category not specifically named among the six security protection items in Huawei's SD-WAN documentation. Encryption (e.g., IPsec VPN) is used for secure tunnels but is not listed as one of the six application-layer protections.

QoS (Quality of Service)is thetechnology used to prioritize and guarantee bandwidthand latency performance forVIP users and mission-critical applications. It enables:

Traffic classification and prioritization

Bandwidth guarantees and rate limiting

Low latency paths for real-time services

A. IPsec VPN– Provides secure tunneling, not traffic prioritization

B. SSH and C. SSL– Offerencryptionfor secure access, but not performance assurance
