H19-301_V4.0 Practice Questions

In Huawei's data center network architecture, an underlay network refers to the physical infrastructure comprising switches, routers, and other network equipment (e.g., VAS devices), responsible for basic IP connectivity. This supports statement

B.  

The overlay network is logically built on top of the underlay and uses tunneling protocols such as VXLAN (MAC-in-UDP) to encapsulate Layer 2/Layer 3 service traffic. This encapsulation ensures transparent delivery of packets across IP underlays. This supports both C and

D.  

Statement A is incorrect: even when using an overlay, the underlay still requires routing protocols (like OSPF, BGP) or static routes to ensure IP reachability between VXLAN Tunnel Endpoints (VTEPs). Overlay tunnels ride on top of this IP connectivity.

The Huawei NetEngine AR8700-8 is a high-performance, high-reliability converged gateway designed for complex WAN edge scenarios such as:

Enterprise headquarters

Financial institutions or headquarters

Large campuses

It provides high forwarding performance, integrated SD-WAN capabilities, intelligent traffic steering, application identification, and security features (e.g., built-in firewall, IPS, etc.).

Refueling and retail headquarters typically require smaller, more compact edge devices (such as AR600 or AR6100 series), rather than a full-scale high-performance router like the AR8700.
