• A
  75% (33)
• C
  25% (11)

Explanation

Options A, B, and D correctly describe WLAN site survey considerations for their respective environments. In office scenarios (A), load-bearing columns and internal partitions are significant physical obstacles that create signal dead zones, so AP placement must carefully account for these structural features. In school classrooms (B), reinforced concrete walls cause severe signal attenuation (typically 15–30+ dB loss), requiring more APs or higher transmit power compared to standard drywall environments. In stadium scenarios (D), the complex physical layout and cable-routing difficulties make traditional ceiling-mount deployments impractical, so distributed antenna systems (DAS) or directional APs aimed at seating sections are the standard solution.

Option C is incorrect because hospital ward environments actually have very high requirements for all three factors mentioned (coverage strength, seamless roaming, and interference immunity) - medical devices and mobile clinical carts demand reliable, uninterrupted connectivity. A statement downplaying these requirements misrepresents the scenario's real-world demands.

Memory tip: Match the environment to its dominant challenge - Office = obstacles, School = material attenuation, Stadium = wiring complexity, Hospital = everything matters (coverage + roaming + interference). If a statement undersells hospital WLAN requirements, it's almost certainly wrong.
