VXLAN (Virtual Extensible LAN) technology uses MAC-in-UDP encapsulation to extend Layer 2 networks over Layer 3 networks.

It encapsulates the original Ethernet frame into a UDP packet, allowing it to traverse an IP network.

VXLAN decouples the logical network from the underlying physical network, meaning MAC addresses of VMs are encapsulated and do not affect the routing of packets across the IP underlay.

VXLAN supports large-scale network expansion with up to 16 million VXLAN segments (compared to 4096 VLANs).

Furthermore, because VXLAN uses a routed underlay network, VM migration is not restricted by Layer 2 boundaries.

TheNetEngine 8000 M14 and M8aremodular high-performance WAN routers. Theirdepth is significantly more than 220 mm. For example:

NetEngine 8000 M8: Approx.600 mmdepth

NetEngine 8000 M14: Larger chassis — deeper than600 mm

A depth of220 mmwould be typical of very compact devices (e.g., small access routers), not these high-capacity modular systems.

The wireless throughput of an AP is primarily influenced by physical layer factors such as:

A. Spatial Streams: More spatial streams allow more simultaneous data channels.

B. Frequency Bandwidth: Wider channels (e.g., 40 MHz, 80 MHz, or 160 MHz) allow more data to be transmitted.

D. SNR: Higher signal-to-noise ratio leads to higher modulation levels and throughput.

Option C (CPU performance) affects the system's ability to process traffic at the application or system level, but not the physical-layer wireless rate. CPU performance may affect total packet forwarding but is not directly a factor in wireless transmission rate.

The Huawei NetEngine AR651EW is a compact, all-in-one enterprise branch router that integrates:

LTE uplink

Wi-Fi 6 capability (802.11ax)

SD-WAN access

Security functions such as IPS and firewall

It is indeed Huawei's first edge router with built-in Wi-Fi 6 functionality, targeting small and medium-sized enterprise branches that require wireless access and SD-WAN features in a single device.

Huawei's six comprehensive border security protection capabilities for SD-WAN or converged gateway routers typically include:

Built-in Firewall – Provides basic packet filtering and security zoning.

Remote URL Filtering – Uses cloud-based services to filter harmful websites.

Antivirus – Detects and blocks malicious files.

IPS (Intrusion Prevention System) – Detects and blocks known threats and attack signatures.

Application-level ACL – Allows granular control of applications beyond Layer 4 (e.g., blocking TikTok, WhatsApp, etc.).

Data leakage prevention (DLP) and behavioral analytics may also be included depending on the security license.

However, "Data encryption" is a broader category not specifically named among the six security protection items in Huawei's SD-WAN documentation. Encryption (e.g., IPsec VPN) is used for secure tunnels but is not listed as one of the six application-layer protections.

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.

Huawei defines theWLAN network lifecycleusing acomprehensive four-stage model, which includes:

B. Plan: Network coverage, capacity, and performance planning

A. Construct: Deployment of APs, controllers, and configurations

C. Maintain: Ongoing network operation and fault handling

D. Optimize: Performance tuning, channel optimization, and roaming refinement

These stages are covered in theWLAN planning and deployment methodologyusing tools likeSCTandiMaster NCE-Campus.

Thefive-layer TCP/IP modelconsists of the following layers:

Application layer

Transport layer

Network layer

Data link layer

Physical layer

A. Application layer– Handles application-level protocols (e.g., HTTP, FTP).

B. Network layer– Handles logical addressing and routing (e.g., IP).

D. Transport layer– Manages end-to-end connections and reliability (e.g., TCP, UDP).

C. Radio layeris not part of the standard TCP/IP model — it's relevant in wireless physical-layer communication, butnot defined in the TCP/IP layering structure.

TheHuawei NetEngine AR6710-L14T2X4is a high-performance enterprise gateway router thatsupports more than just SD-WAN and switch convergence. It also supports:

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.

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.

Huawei’s"1-3-5" troubleshooting model, powered byknowledge graphs and AI-driven analysis, enables:
