CloudCampus Solution is a cloud-based network management platform that provides plug-and-play of devices using three common deployment modes: QR code scanning for deployment, DHCP Option 148, and registration query center deployment . QR code scanning for deployment allows users to scan the QR code on the device label using a mobile app and automatically add the device to the cloud platform . DHCP Option 148 allows devices to obtain the cloud platform address from a DHCP server and automatically register with the cloud platform . Registration query center deployment allows devices to obtain the cloud platform address from a registration query center server and automatically register with the cloud platform . These deployment modes simplify the network configuration and management process and reduce the OPEX .

NE8000 M14 cannot be deployed in a 300 mm-deep cabinet. According to the Huawei NetEngine 8000 M14 Routers Support Guide1, the NE8000 M14 requires a cabinet with a depth of at least 800 mm.

Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

The CloudEngine 16800 series switches do not support 4, 8, 12, and 16 LPU slots. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 series switches support three models: CE16804 (4 LPU slots), CE16808 (8 LPU slots), and CE16816 (16 LPU slots). There is no model that supports 12 LPU slots.

Huawei AirEngine 8760X1-PRO is not Huawei’s flagship Wi-Fi 6 model. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei AirEngine 8760X1-PRO is a high-performance Wi-Fi 6 AP that supports 16 spatial streams and a rate of up to 10.75 Gbit/s, but it is not the flagship model. The flagship model is Huawei AirEngine 8760R-PRO, which supports 24 spatial streams and a rate of up to 16.13 Gbit/s.

Compared with common Ethernet, the NOF+ scenario greatly improves usability and reliability. According to the Huawei CloudFabric Data Center Network Solution White Paper, NOF+ (Network-Oriented Fabric+) is a data center network architecture that supports both Layer 2 and Layer 3 connectivity between servers and leaf nodes. NOF+ uses VXLAN technology to create overlay networks on top of theunderlay network, which improves network scalability, flexibility, and security. NOF+ also uses M-LAG technology to provide link redundancy and load balancing between leaf nodes and servers, which improves network availability and performance.

AirEngine 8760-Xi-PRO is Huawei’s flagship Wi-Fi 6 product that has a unique industrial design with features such as an 18-degree angle of tilt for network ports and optical ports, a shark fin bionic heat dissipation channel, and a removable cover for IoT card installation . These features are designed to improve the performance, reliability, and convenience of the product. Easy and flexible is not an industrial design feature of the AirEngine 8760-Xi-PRO, but rather a general description of its deployment and management capabilities .

WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases . WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3. WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .

 NE8000 X4 and X8 are high-end core routers designed for large-scale IP backbone networks, data centers, and metro networks . They support various redundancy designs to ensure high availability and reliability, such as MPU (Main Processing Unit) 1+1 backup, SFU (Switch Fabric Unit) 7+1 backup, and PEM (Power Entry Module) 1+1 backup . MPU 1+1 backup means that two MPUs work in active/standbymode and provide control plane redundancy . SFU 7+1 backup means that eight SFUs work in N+1 mode and provide data plane redundancy . PEM 1+1 backup means that two PEMs work in active/standby mode and provide power supply redundancy . The NE8000 X4 and X8 do not support power supply 9+1 backup, which is a feature of the NE8000 X16 router .

Huawei AirEngine 6760 series supports four spatial streams by default, but after an RTU (Right To Use) license is purchased, it can support up to eight spatial streams on the 5 GHz band. It can also support four spatial streams on the 2.4 GHz band or scanning mode. Therefore, the possible spatial stream combinations are 4+8, 4+8+4, 4+4+scanning, and 4+6+scanning.

The NE8000M1C supports dual AC/DC power modules. According to the NetEngine 8000 M1C Service Router Datasheet, NE8000M1C supports two power modules that can work in 1+1 redundancy mode. The power modules can be AC or DC power modules.
