Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 190

A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of office cubicles. Which signal propagation attenuation result is associated with this environment?

Answer options

• A. reflection
• B. absorption
• C. noise
• D. refraction

Correct answer: B

Explanation

Absorption is the correct answer because the materials used in office cubicles, such as partitions and furniture, can absorb wireless signals, leading to a decrease in signal strength. Reflection and refraction are less significant in this scenario as they deal with changes in direction rather than signal strength reduction. Noise typically refers to interference rather than attenuation caused by physical barriers.
