Huawei H19-401_V1.0 HCSP-Presales-Campus Network Planning and Design V1.0 Exam Practice Test

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.

Huawei’s SD-WAN solution includes WAN optimization technologies to improve performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

A: Packet loss mitigation (e.g., FEC/A-FEC) recovers lost packets.

B: Transmission optimization enhances link efficiency (e.g., via compression).

C: Data optimization reduces bandwidth usage (e.g., deduplication).

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.

Antenna choice depends on coverage needs. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation states:

EVPN link templates enhance reliability. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

A, D, E: These are default templates for single-gateway scenarios.

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.

Clustering algorithms in CampusInsight identify connectivity patterns. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

A, B: SSID and vendor are used to group devices and analyze issues.

Network Access Control (NAC) involves multiple roles to enforce security policies. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation defines these roles as:

Admission Device: This is the network device (e.g., switch or AP) that enforces access control policies and initiates authentication (e.g., as an 802.1X authenticator). It is a key NAC component.

User Terminal: The endpoint device (e.g., laptop, smartphone) requesting network access. It interacts with the admission device and often runs a supplicant for authentication.

User: While the user is the human entity accessing the network, NAC terminology focuses on technical components (devices and servers) rather than the user as a "role" in the process.

In network security, AAA (Authentication, Authorization, and Accounting) is a framework for controlling access to network resources. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation explains that a campus switch can function as a local AAA server when it is configured to handle AAA processes internally, without relying on an external server like RADIUS or TACACS+.

When acting as a local AAA server, the switch maintains a local user database and performs authentication (verifying user identity), authorization (determining user privileges), and accounting (tracking user activity). This is particularly useful in small networks or scenarios where connectivity to an external AAA server is unavailable.

Redirect sites are topology-specific. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation notes:

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.

Simplified deployment eases SD-WAN setup. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

B, C, D: Wizard-based, fast, and batch deployment are key features.

Huawei’s free mobility solution enhances user authentication and access control by synchronizing IP-security group entries across devices, ensuring seamless policy enforcement. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies:

Switches: Campus switches (e.g., CloudEngine series) can act as access devices, authenticating terminals via methods like 802.1X or MAC authentication. They support IP-security group synchronization to enforce consistent policies.

APs (Access Points): Wireless APs (e.g., AirEngine series) serve as access devices in WLAN scenarios, authenticating terminals via 802.1X, portal, or MAC methods. They also participate in IP-security group synchronization for mobility.

AR (Access Routers): While AR routers (e.g., NetEngine AR series) can perform authentication in certain contexts, they are typically not access devices in the free mobility solution’s context, focusing instead on routing and WAN functions.

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

WLAN capacity design ensures performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:

Huawei’s CloudCampus Solution simplifies network deployment through automation. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation states:

The automatic routing domain configuration function, managed by iMaster NCE-Campus, enables the automatic deployment of dynamic routing protocols (e.g., OSPF) on the underlay network. This ensures IP reachability between fabric nodes without manual configuration.

User Experience 360 in iMaster NCE-CampusInsight provides visibility into user performance. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation states:

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.
