In the Mesh networking of WLAN network, APs are connected by wireless. Compared with the traditional WLAN network where the AP uplink uses a wired network, which of the following is not an advantage…

Question

Options

• ALow network construction cost
• BGood anti-interference ability
• CFlexible networking
• DWide application scenarios, such as mines, docks, etc.

• A
  6% (4)
• B
  9% (6)
• C
  3% (2)
• D
  83% (57)

Explanation

D is the correct answer because "wide application scenarios such as mines and docks" describes a use case or deployment context, not a technical advantage of Mesh over traditional WLAN. Mines and docks benefit from Mesh precisely because of the other advantages (cost, flexibility), so listing the scenario is redundant - it's a consequence, not an advantage in itself.

Why the distractors are wrong (they ARE genuine advantages):

• A is an advantage: Mesh eliminates costly cable runs to every AP, significantly lowering infrastructure costs.
• B is an advantage: The multi-hop wireless topology allows traffic to reroute around interference sources, something a single-uplink wired AP cannot do.
• C is an advantage: APs can be added, removed, or repositioned freely without pulling new cables, making the network highly adaptable.

Memory tip: Think of it as "HOW vs. WHERE." A, B, and C explain how Mesh works better (cheaper, resilient, flexible) - these are technical advantages. D only says where you can deploy it, which is downstream of those advantages, not an advantage itself. On exam questions like this, watch for options that describe applications or scenarios rather than technical properties.
