Huawei SD-WAN supports full-mesh, hub-spoke, and partial-mesh interconnection models. In a full-mesh topology, every site can communicate directly with the other sites. This model minimizes intermediate forwarding and is appropriate when branches frequently exchange latency-sensitive traffic such as voice, video, or collaborative application data.

In a hub-spoke topology, branch sites communicate with a central headquarters or data-center hub. Branch-to-branch traffic normally traverses that hub. The model is simple, scalable, and suitable for enterprises whose applications and shared resources are concentrated at headquarters.

Partial-mesh is used when most sites can communicate directly but some sites lack direct underlay connectivity or do not require direct tunnels. Those sites can communicate through a redirect or intermediate site. Huawei describes full-mesh, hub-spoke, and partial-mesh as supported topology designs and explains the role of a redirect site in partial-mesh networking.

“Partial-spoke” is not a defined SD-WAN topology model. A spoke is a role within hub-spoke networking rather than an independent partial-spoke topology. Therefore, A, B, and D are correct.

==================

All four statements correctly describe the trade-offs between direct and tunnel forwarding. With direct forwarding, an AP sends service traffic directly to the upstream network rather than encapsulating it in a CAPWAP data tunnel to the WA

C.  

However, on a fabric network, Layer 3 roaming across different edge nodes may require the original edge or another designated device to remain the home agent. The resulting forwarding path and state synchronization can slightly affect roaming performance, making direct forwarding less suitable for extremely roaming-sensitive deployments. Huawei’s material explains that after Layer 3 roaming in direct-forwarding mode, traffic may continue to be forwarded through the home agent.

Tunnel forwarding sends AP service traffic through CAPWAP tunnels to the WA

==================

All four options represent objectives of a next-generation advanced industrial network. IP-based connections establish a standardized communications foundation, allowing production systems, controllers, sensors, machines, and management platforms to communicate through scalable Ethernet and IP technologies instead of isolated proprietary field networks.

Networked devices extend connectivity across operational technology assets so that equipment status, production data, and control information can be shared across production lines, plants, data centers, and cloud platforms. Network intelligence introduces automated provisioning, telemetry, analytics, fault prediction, policy optimization, and closed-loop operations. These capabilities reduce manual configuration and improve production availability.

Network-security integration is equally essential because greater openness and interconnection increase the potential attack surface. Security must therefore be integrated into access control, segmentation, device identification, encrypted communication, anomaly detection, and policy enforcement rather than added as an isolated external system. Huawei’s broader CloudCampus architecture similarly emphasizes automated provisioning, intelligent O & M, secure interconnection, integrated wired and wireless management, and open network capabilities. The four objectives collectively create an open, connected, intelligent, and secure industrial communications architecture.
