Regarding the networking method, which of the following description is correct?

Question

Options

• ACompared with the three-layer network, the two-layer network is more suitable for large-scale
• BThe advantages of the three-tier network are simple configuration and easy networking
• CIf the ability of AC to process data is relatively weak, it is recommended to use side-mounted
• DIn the direct-connected network, the business data of the AP can directly reach the uplink network

• A
  4% (1)
• B
  13% (3)
• C
  79% (19)
• D
  4% (1)

Explanation

Option C is correct because in a side-mounted (bypass) deployment, the AC handles only control and management traffic while business data from APs flows directly through the switching infrastructure to the uplink network, bypassing the AC entirely. This significantly reduces the processing burden on the AC, making it the right choice when the AC has limited data-handling capacity.

Option A is wrong because three-layer networks (core, aggregation, access) are better suited for large-scale deployments due to their superior scalability, redundancy, and traffic management; two-layer networks are simpler and more appropriate for smaller environments. Option B is wrong because simple configuration and easy networking are advantages of two-layer architectures, not three-layer ones; three-layer networks are more complex to configure but offer better performance at scale. Option D is wrong because in a direct-connected network, the AC sits inline in the data path, meaning all AP business data must pass through the AC before reaching the uplink network, not directly to it; it is the side-mounted topology where data can bypass the AC.

Memory tip: Think of "side-mounted" as the AC stepping aside from the data path. When the AC is weak, let it step aside so heavy data traffic flows around it, not through it.
