In Huawei’s spine-leaf data center network (DCN) architecture, the topology consists of spine nodes (core) and leaf nodes (access/aggregation). Leaf nodes can serve different roles:
Border Leaf Node:Connects the DCN to external networks or other domains, handling Layer 3 routing.
Service Leaf Node:Connects to internal services (e.g., servers, VMs), often handling Layer 2/Layer 3 traffic.
In practice, a single physical device can be configured to perform both roles (border and service) if it has the necessary interfaces and routing capabilities. Huawei’s CloudFabric documentation supports this flexibility, allowing a leaf switch to act as both a border and service node based on configuration (e.g., using VRFs or VXLAN gateways). This reduces hardware costs and simplifies deployment in smaller DCNs.
The statement isTRUE (A)because the border leaf and service leaf roles can be deployed on the same device in a spine-leaf architecture.References:Huawei CloudFabric Data Center Network Solution – Spine-Leaf Design; HCIP-Data Center Network Training – Leaf Node Roles.
