HCSP-Presales-Campus Network Planning and Design V1.0 H19-401_V1.0 Exam Questions with Experts Answers Updated Recently

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.

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.
