Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 14

What causes the most signal attenuation, based on the wireless design tools?

Answer options

• A. cinder block wall
• B. metal door
• C. glass wall
• D. office window

Correct answer: B

Explanation

The metal door causes the most signal attenuation due to its density and ability to reflect signals, which significantly impacts wireless communication. In contrast, while a cinder block wall does attenuate signals, it is generally not as effective as a metal door. Glass walls and office windows have minimal impact on signal strength compared to these materials.
