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.

TheSolution Configuration Tool (SCT)supports:

Viewing products(A)

Comparing products(C)

Configuring product components(D)

However,B. Ordering the products directlyisnot availablein SCT. SCT is aconfiguration and solution design tool, not a purchasing platform. Orders must be placed through authorized Huawei sales channels or partner platforms.

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.
