Huawei H19-401_V2.0 Dumps - Pass HCSP-Presales-Campus Network Planning and Design V2.0 Exam in First Attempt 2026

In the latest Huawei Xinghe Intelligent Campus (V2.0) architecture, the network is officially categorized into a four-layer architecture: Terminal Layer, Network Layer (which includes Access, Aggregation, and Core), Management Layer (iMaster NCE), and Application Layer. While the components mentioned (Egress, O&M) are physical zones, the 'Typical Architecture' definition in HCSP documentation distinguishes between the layers of the infrastructure and the functional zones. Furthermore, in many modern SDN-based designs (like the Xinghe solution), the aggregation layer is often optional or collapsed, and the 'O&M zone' is formally referred to as the Management and Analytics Layer.

Huawei's Intelligent Energy Saving Solution (Zero-bit, Zero-watt) uses AI to transition APs between states based on traffic demand. In this logic:

Energy-saving APs (A): Are those identified by the system to enter a deep sleep/hibernation mode when traffic is low.

Assurance APs (D): Remain active to provide basic signal coverage and 'listen' for wake-up triggers.

Leader APs (C): Function as the local controller (in small-scale deployments) to coordinate these states.

IoT APs (B), while they support converged services, are not defined as a specific functional role within the energy-saving state-switching algorithm itself, as IoT devices often require persistent, low-power connectivity that differs from standard Wi-Fi user traffic patterns.

Huawei's SD-WAN solution supports dual-stack (IPv4/IPv6) networking. This means that overlay tunnels (typically IPsec) can be established regardless of whether the underlying transport network (Internet, MPLS, or LTE) uses IPv4 or IPv6. This is a critical feature for enterprises undergoing transition, allowing them to build a unified virtual private network over heterogeneous physical infrastructures.

The Huawei Xinghe Intelligent Campus leverages SDN to deliver four core benefits:

Open Programmability (A): Via Northbound APIs for integration with 3rd-party apps.

Network Automation (B): Automating full-lifecycle O&M.

Rapid Service Provisioning (C): Reducing deployment time from weeks to minutes via templates.

Network Virtualization (D): Using VXLAN/EVPN to create multiple isolated logical networks (e.g., IoT, Office, Security) on a single physical infrastructure.

In Huawei's Xinghe Intelligent Campus solution, user access control is handled through three primary methods: 802.1X (B) for high-security enterprise environments, Portal (A) for flexible guest and web-based access, and MAC address authentication (C) for IoT devices like printers and IP cameras that lack a user interface. OSPF authentication (D) is a routing security feature used to verify the identity of neighboring routers, not an end-user access authentication method.
