WLAN (Wireless Local Area Network) specifically refers to wireless networks based on the IEEE 802.11 standards , which are commonly known as Wi-Fi . While infrared, Bluetooth, and ZigBee are 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 is incorrect , making the correct answer False .

Huawei’s HiSec Endpoint is an endpoint detection and response (EDR) solution that:

Provides 24/7 active protection against ransomware using behavior-based detection, AI algorithms, and rollback mechanisms.

Integrates anti-ransomware engines to detect encryption behaviors in real time.

Ensures zero data loss via file protection, backup, and instant recovery .

It is widely deployed in sectors where data security on endpoints is critical , including finance, government, and healthcare.

Huawei’s Wi-Fi Shield technology is designed to enhance WLAN security and includes features such as:

Unauthorized terminal detection and suppression

Data encryption and integrity protection

Air interface behavior analysis to block rogue APs or attackers

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

Huawei identifies the transition from digital to intelligent transformation as a phase where enterprise data communication networks face several new challenges , such as:

High-density wireless connectivity demands

Heavy use of video-based and real-time applications

The exponential growth of AI computing power

Critical workloads moving to public and hybrid cloud platforms

Ever-evolving cybersecurity threats

These are outlined in the context of building Net5.5G-ready networks to address such demands.

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.

A. True : The AirEngine 6760R-51 , a rugged outdoor Wi-Fi 6 AP, supports IoT expansion via Huawei’s IoT cards .

B. False : Huawei IoT expansion is implemented via IoT cards and dedicated expansion modules , not PCIe or USB .

C. False : Huawei supports multiple IoT protocols , including BLE, RFID, Zigbee , and NB-IoT , not just RFID and Bluetooth.

D. False : Although Huawei minimizes interference through smart scheduling, some spectrum overlap may still occur , and co-channel interference is always considered in planning .

In Huawei’s SD-WAN solution , RRs (Route Reflectors) perform key functions:

A. True – RRs distribute VPN and tunnel routes based on SD-WAN VPN topologies.

C. True – RRs can be deployed on physical AR routers or virtualized AR6700V-L instances .

D. True – RRs transmit BGP routes , reducing the number of BGP peer sessions needed between CPEs.

B. False – RRs do not need to be deployed independently . They can be collocated with other roles or functions , particularly in smaller or virtual environments.

Therefore, statement B is false .

In Huawei firewall deployments (such as USG6000 series), using a single firewall at the network egress creates a single point of failure (SPOF).

To improve reliability, Huawei supports firewall stacking technology, called FW-Stack.

In a firewall stack, multiple firewalls form a single logical device.

Advantages of firewall stacking include:

Unified management: Only the stack system is configured and managed, not individual members.

Seamless failover: If a member firewall fails, services continue on other members.

Increased throughput: Aggregate performance of multiple firewalls.

This setup greatly enhances service continuity and improves network reliability without needing complex configuration across devices.

iMaster NCE-Campus is Huawei’s intelligent network management and control system for enterprise networks. It supports:

Unified management of both LAN and WAN devices

Real-time traffic monitoring with visibility down to application and user levels

AI-based fault diagnosis and O & M automation

These capabilities reduce manual effort and improve efficiency in daily network operations and troubleshooting.

In the SCP (Solution Configuration Platform) , you can view the lifecycle statuses of:

A. Components/part numbers : You can see information like General Availability (GA), End of Sale (EOS), End of Maintenance (EOM), and End of Support (EOS).

C. Products : Product lifecycle status, including planned phase-out timelines, is also available.

B. Solutions and D. BOQs (Bill of Quantities) are not associated directly with lifecycle management . BOQs are outcome documents generated after configuration, and solutions are broader design packages.
