Answer : A

Inter-WAC roaming involves moving a user's session information between two different physical or logical controllers. This process is inherently slower and more prone to packet loss or authentication delays than Intra-WAC roaming (where the user moves between APs managed by the same WAC). In the Xinghe Intelligent Campus design, Huawei recommends using Native WACs on core switches or stacking WACs to create a single large mobility domain, thereby minimizing the need for inter-WAC handovers.

Answer : C

The iMaster NCE-Campus controller monitors the network via protocols like SNMP, NETCONF, and Telemetry to provide visibility into application traffic (A), topology (B), and link stats (D). However, original/raw NetStream flow information (C) is typically too voluminous for a management controller to process. Instead, these raw packets are sent to a dedicated Analyzer (like iMaster NCE-CampusInsight) which performs deep data mining. The controller only receives summarized reports or metadata from the analyzer.

Answer : A

MIMO (Multiple-Input Multiple-Output) is a core pillar of modern WLAN planning. It utilizes two main techniques:

Spatial Multiplexing (SM): Increases system capacity by transmitting different data streams over different antennas simultaneously.

Spatial Diversity (SD): Improves coverage scope and SNR (Signal-to-Noise Ratio) by transmitting the same data stream over multiple paths to ensure reliability through redundancy (e.g., using MRC or STBC).

The statement is True because these benefits are achieved using the same frequency channel (no extra bandwidth) by exploiting the spatial dimension of the radio environment.

Answer : A, B, C

A functional Huawei SD-WAN network requires three fundamental pillars:

CPE (A): The physical or virtual edge device at the branch/HQ.

RR (B): The control plane component that reflects routes between CPEs.

Controller (C): The management plane (iMaster NCE-Campus) for orchestration and policy deployment.

The Analyzer (D) (CampusInsight) is an optional component used for advanced AI-driven O&M and troubleshooting, but it is not strictly required to establish the SD-WAN network itself.

Answer : A

For high-density and large-scale environments, the Native WAC (integrated into the core switch software/hardware, like on the S12700E or S16700) is the preferred recommendation. Unlike a standalone AC, a Native WAC leverages the massive switching capacity of the core switch's forwarding chips to process wireless data at line rate. It simplifies the network by eliminating the need for external AC hardware and provides the scalability required to manage thousands of APs and tens of thousands of terminals within a single management framework.
