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

FireHunter is Huawei’s APT detection system, integrated into campus and SD-WAN solutions. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation confirms:

It uses sandboxing with multi-engine virtualized detection to analyze static (code) and dynamic (runtime) software behavior.

Overlay topology is managed in SD-WAN. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation explains:

A, C, D: These align with overlay control mechanisms.

Huawei’s SD-WAN architecture is multi-layered. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation defines:

A: Control layer (e.g., RR) manages routing and overlay topology.

B: Network layer (e.g., CPEs) handles data transmission.

C: Management layer (e.g., iMaster NCE) oversees configuration and monitoring.

In the Huawei public cloud scenario, the platform operator manages the cloud infrastructure. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation outlines:

Platform Operator Responsibilities: Include cloud platform O&M (B), collecting network statistics (C), and MSP management (D) to ensure service delivery and oversight.

AP modes differ in management. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation explains:

A: Fat APs are standalone, manually configured, simple, and cost-effective—true.

B: Fat APs are not centrally managed by a WAC (Wireless Access Controller); this applies to Fit APs—false.

C: Cloud-mode APs are managed by iMaster NCE, not WACs, but this varies by deployment—partially true but not definitive.

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.

802.1X is a port-based network access control (NAC) protocol widely used for securing wired and wireless networks. It relies on the Extensible Authentication Protocol (EAP) to facilitate authentication between a supplicant (client) and an authentication server (typically a RADIUS server). The HCSP-Presales-Campus Network Planning and Design V1.0 documentation highlights two primary EAP-based authentication modes in 802.1X deployments: EAP termination and EAP relay.

EAP Termination: In this mode, the authenticator (e.g., a switch or access point) terminates the EAP session and communicates with the authentication server using a protocol like RADIUS. The authenticator extracts the EAP information and forwards credentials to the server in a non-EAP format. This mode is commonly used when the authenticator handles part of the authentication process locally.

EAP Relay: In this mode, the authenticator relays the entire EAP conversation between the supplicant and the authentication server without processing it. The EAP messages are encapsulated (e.g., in RADIUS packets) and sent directly to the server, which performs the full authentication. This mode is preferred for centralized authentication management.

CloudCampus supports dual modes. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation clarifies:

Huawei's free mobility solution is designed to provide seamless user access and authentication across a campus network, often integrating with Network Access Control (NAC) mechanisms like 802.1X, MAC authentication, or portal authentication. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation specifies that the free mobility solution supports interoperability between Huawei devices and third-party devices within the same network.

Third-party devices, such as switches or access points, can function as end-user authentication points (e.g., 802.1X authenticators) as long as they comply with standard protocols like RADIUS or EAP. Huawei’s solution leverages open standards to ensure compatibility, allowing third-party devices to participate in authentication workflows.

Dual-gateway scenarios support multiple protocols. The HCSP-Presales-Campus Network Planning and Design V1.0 documentation lists:
