Layer 2 WLAN networking simplifies deployment. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation notes:

B, D: WAC and APs share a broadcast domain, enabling AP discovery via broadcasts—true.

Data channels in Huawei’s SD-WAN solution carry overlay traffic. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies:

Data channels primarily use IPsec (for security) or VxLAN (for flexibility), not GRE or GRE over IPsec as the default.

Wi-Fi 6 (802.11ax) introduces advanced features to enhance wireless performance, including smart antenna technology. According to the HCSP-Presales-Campus Network Planning and Design V1.0 documentation:

Smart antenna technology in Huawei’s Wi-Fi 6 APs (e.g., AirEngine series) uses adaptive beamforming to dynamically adjust signal direction and strength. This improves coverage and signal quality, particularly for uplink transmissions from stations (STAs) to the AP.

The focus is on medium- and long-distance uplink performance, as smart antennas mitigate signal attenuation over distance, ensuring reliable connectivity for devices farther from the AP.

Device registration in the Huawei public cloud scenario is critical for cloud management. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation identifies:

A: Incorrect registration configuration (e.g., wrong serial number or authentication code) prevents successful registration.

B: Failure to obtain an IP address (e.g., DHCP issues) blocks communication with the cloud platform.

C: While licensing is required for functionality, it is not a direct cause of registration failure; registration precedes license checks.

Huawei’s SD-WAN solution comprises specific components. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation highlights:

C: iMaster NCE is the management and control platform.

E: CPE (Customer Premises Equipment) is the edge device for connectivity.

A (NE): Network Element is a generic term, not a specific SD-WAN component.

B (Gateway): Used in some contexts but not a key SD-WAN component.

Network Access Control (NAC) is a critical security framework for managing endpoint access to a network. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation outlines various NAC methods and their characteristics:

A. MAC Address Authentication: This method relies on the unique MAC address of a device for authentication. In most cases, it requires administrators to manually register MAC addresses in adatabase (e.g., on a RADIUS server), which increases management complexity, especially in large or dynamic networks. This statement is true.

B. 802.1X Authentication Requirements: Contrary to the statement, 802.1X authentication typically has high requirements for client software, as it requires a supplicant (e.g., a compatible client supporting EAP) to be installed and configured on user terminals. This limits its flexibility in environments with diverse or unmanaged devices, making the statement false.

C. 802.1X Authentication Applicability: 802.1X is ideal for newly deployed networks with centralized user bases (e.g., enterprise campuses) and stringent security needs, as it enforces strong authentication (e.g., via EAP-TLS). This aligns with its use in controlled, high-security environments, making the statement true.

Management channels in Huawei’s SD-WAN solution (via iMaster NCE) handle configuration delivery. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation states:

C: Unified management of CPEs, automatic service delivery, and overlay network control are core functions of management channels.

Local Internet access is flexible. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:
