H19-401_V2.0 Practice Questions

In Huawei’s Xinghe Intelligent Campus solution, user access control is handled through three primary methods: 802.1X (B) for high-security enterprise environments, Portal (A) for flexible guest and web-based access, and MAC address authentication (C) for IoT devices like printers and IP cameras that lack a user interface. OSPF authentication (D) is a routing security feature used to verify the identity of neighboring routers, not an end-user access authentication method.

Huawei’s SD-WAN solution offers the industry's most flexible networking architectures. The supported modes include:

Hub-spoke (A): Best for star-shaped enterprise layouts where branches talk through a HQ.

Full-mesh (D): Every site talks directly to every other site (best for low-latency VoIP/Video).

Partial-mesh (C): A hybrid approach where only specific key sites are interconnected.

Hierarchical (B): Used for massive networks (over 1,000 sites), dividing the network into regions to improve scalability and management.

Huawei's Xinghe Intelligent Campus defines three standard "Access Authentication" modes for users and terminals:

802.1X (B): High security, suitable for PCs and mobile devices with clients.

Portal (C): Common for guest access and public areas (web-based login).

MAC Address Authentication (A): Used primarily for "dumb" terminals like printers, cameras, and IoT devices that cannot perform 802.1X/Portal logins.

OSPF Authentication (D) is a protocol-level security feature used to secure routing updates between routers, not an access authentication method for end-user devices.
