Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 244

How does the environment affect the wireless network when conducting a site survey in a multifloor building?

Answer options

• A. Elevator shafts block RF signals.
• B. Stocked supply rooms cause noise floor.
• C. Stocked supply rooms cause reflection.
• D. Elevator shafts cause signal scattering.

Correct answer: A

Explanation

The correct answer is A, as elevator shafts can significantly obstruct RF signals, leading to weak connectivity. While options B and C mention issues related to noise and reflection in supply rooms, they do not directly address physical obstructions like elevator shafts. Option D incorrectly states that elevator shafts cause signal scattering, which is not as impactful as blocking signals.
