On a campus fabric network, which of the following methods can be used for non-authenticated terminals to access a VN?
Answer : A
In a Virtualized Campus Network (Fabric), terminals that do not support authentication protocols (such as simple IP cameras or legacy printers) cannot participate in dynamic authorization processes like 802.1X or Portal. To allow these 'dumb' terminals to access a specific Virtual Network (VN), administrators must manually bind the access port or a specific Static VLAN (A) to the desired VN (VRF) on the Edge node. This ensures the terminal's traffic is correctly encapsulated into the VXLAN overlay.
Which of the following features are key capabilities in multi-branch retail scenarios?
Answer : A, B, C, D
The Xinghe Intelligent Campus for retail focus on four key areas:
SD-Branch (A): Unified management of WAN, LAN, and WLAN for small stores.
Converged IoT (B): Using APs with built-in IoT slots for Electronic Shelf Labels (ESL) or RFID asset tracking.
Hyper-converged Gateway (C): Using devices like the AR series that combine routing, switching, security, and a wireless controller into one box to save space.
Plug-and-play (D): Zero-touch provisioning (ZTP) so that non-technical store staff can simply plug in a device and have it configured automatically by the cloud.
Distributed VXLAN gateways are recommended if VXLAN networking is required.
Answer : A
In a Virtualized Campus Network (Fabric), Huawei recommends Distributed Gateway deployment. In this model, the Layer 3 gateway functionality for a tenant is moved down to the Edge nodes (Access or Aggregation switches). This ensures that 'East-West' traffic (communication between devices in the same subnet but on different switches) is routed locally at the edge, preventing traffic from having to travel up to a centralized core and back down, thus reducing latency and avoiding bottlenecks.
On a campus fabric network, which of the following methods can be used if VNs need to communicate with each other?
Answer : C, D
By default, Virtual Networks (VNs) are isolated from one another as they exist in separate VRFs. To enable inter-VN communication:
Internal Route Leaking (C): Routes are imported/exported between VRFs on the Border Node.
External Traffic Steering (D): Traffic is sent out of the Fabric through the Border Node to an external Firewall or Gateway, which then routes the traffic back into the second VN. This is the preferred method when security inspection between VNs (e.g., Guest VN to Office VN) is required.
Which of the following VLAN networking solutions is recommended when there are 15,000 wireless terminals on the customer's network?
Answer : A
For a large-scale campus network exceeding 10,000 wireless terminals, Huawei's V2.0 design guide recommends the Native WAC solution integrated into flagship core switches (such as the CloudEngine S12700E or S16700). In a traditional three-layer hierarchy (Core-Aggregation-Access), the Native WAC (A) is preferred over a standalone AC because it utilizes the core switch's high-performance ENP/Solar chips to process CAPWAP tunnels at line rate, avoiding the traffic bottlenecks often associated with standalone controllers in high-density environments.
(Note: The user's original answer was B, but according to V2.0 Large Campus best practices for 10k+ terminals, Native WAC is the primary recommendation.)
