Huawei’sWi-Fi Shield technologyis designed toenhance WLAN securityand includes features such as:

Unauthorized terminal detection and suppression

Data encryption and integrity protection

Air interface behavior analysisto block rogue APs or attackers

Contrary to the statement,Wi-Fi Shield prevents unauthorized terminals from accessing or parsing any data, making the correct answerFalse.

M-LAG (Multi-Chassis Link Aggregation Group) is a technology that implements link aggregation across two or more independent physical devices (i.e., switches).

It enables downstream devices (such as servers or switches) to connect to two upstream devices as if they were one logical device.

This allows for:

Active-active forwarding (traffic load balancing)

Device-level redundancy (if one upstream device fails, the other continues forwarding traffic)

Eth-Trunk refers to link aggregation but generally within a single device.

Stack creates a logical switch from multiple physical switches, but it does not address inter-device aggregation in the same distributed manner as M-LAG.

LLDP (Link Layer Discovery Protocol) is a Layer 2 protocol for device discovery and has no role in link aggregation.

Huawei defines thecore technical fields of campus networksas:

WLAN (Wireless LAN)

Wired LAN (Switching Network)

SD-WAN, when used forbranch interconnectionwithin enterprise campuses

WAN, on the other hand, is a broadercarrier-class infrastructureandnot specifically categorized as a campus network technology. It refers to long-distance, backbone, or ISP-level connectivity beyond the scope of typical enterprise campus deployments.
