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.

MAC address authentication (also known as MAC bypass authentication) is typically used for non-intelligent endpoints such as printers, IP phones, and IoT devices that cannot run client software or access a portal for login.

The authentication process is completed by identifying the device’s MAC address and mapping it to predefined policies in the NAC system.

It does not require client installation or human interaction — making it ideal for “dumb terminals.”

By contrast, 802.1X and portal authentication require software clients or web-based logins and are designed for user-driven authentication.

WLAN (Wireless Local Area Network)specifically refers towireless networks based on the IEEE 802.11 standards, which arecommonly known as Wi-Fi. Whileinfrared, Bluetooth, and ZigBeeare also wireless technologies,they are not part of WLAN:

Wi-Fi (802.11)= WLAN

Bluetooth, ZigBee, Infrared= PAN or IoT technologies, not WLAN

Thus, grouping all these under WLAN isincorrect, making the correct answerFalse.

HuaweiAirEngine APswith theleader AP featureare capable of managing Fit APs insmall-scale or branch networks. The supportedforwarding modesinclude:

A. Tunnel forwarding: Traffic is encapsulated and sent to the gateway (leader AP or AC)

B. Direct forwarding: Traffic exits directly at the AP to reduce latency

Bridge forwardingandroute forwardingare not standard forwarding modes in this context.Bridge modegenerally applies to Layer 2 switching, androute forwardingpertains to Layer 3 routers, not WLAN forwarding at the AP level.

A. Camerais not a core data center component; it may be connected via separatesurveillance or edge networks, not the maindata center network fabric.

Segment Routing (SR) introduces a source routing model where the source node defines the path that packets take through the network by imposing a list of segments (instructions).

SR is aligned with SDN principles — the network is programmable and flexible.

SR does NOT depend on LDP or RSVP. Instead, SR uses extensions to IGP (OSPF or IS-IS) or BGP to distribute segment information.

SR simplifies the control plane by reducing the number of protocols needed for label distribution.

SR can work with or without a controller — the controller enhances path computation but is not mandatory for basic SR operation.
