Pass the Huawei Certification H19-401_V1.0 Questions and answers with ValidTests

Radio signal attenuation varies by material. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation notes:

C, D: Metal and reinforced concrete significantly attenuate signals, requiring careful survey attention.

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.

Wi-Fi 6 (802.11ax) is an evolution of previous Wi-Fi standards, designed to improve efficiency and capacity. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:

Wi-Fi 6 operates on both the 2.4 GHz and 5 GHz frequency bands, maintaining compatibility with legacy devices while introducing enhancements like OFDMA and MU-MIMO.

Low throughput has multiple causes. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation explains:

PoE standards define power delivery. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation states:

A: IEEE 802.3at (PoE+) delivers up to 25.5 W, true.

B: IEEE 802.3bt (PoE++) delivers up to 71-90 W (not exactly 81.6 W, but close), generally true.

C: IEEE 802.3af (PoE) delivers 12.95 W, true.

Site division has trade-offs. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation notes:

SD-WAN roles define permissions. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:

Directional antennas focus signals within beamwidths. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies:

Signals exist outside beamwidths, though weakened, contradicting the "no signal" claim.

Wi-Fi 6 leverages Orthogonal Frequency Division Multiple Access (OFDMA) and Multi-User Multiple-Input Multiple-Output (MU-MIMO) to enhance multi-user performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies their roles:

OFDMA: Divides frequency resources into smaller subcarriers (resource units), allowing multiple users to transmit simultaneously. It excels in small-packet transmission scenarios (e.g., IoT devices, VoIP) due to its ability to efficiently allocate bandwidth for low-data-rate streams.

iMaster NCE-CampusInsight’s protocol trace analyzes network behavior. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:

A, B, C: User access time, connected AP, and MAC address/username are traceable details.
