Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 58

Why is 802.11a connectivity reduced in an X-ray room?

Answer options

• A. X-rays create significant non-Wi-Fi interference on the 802.11a band.
• B. X-rays impact the 802.11a UNII-2 channels that cause access points to dynamically change channels.
• C. X-rays within these rooms cause multipath issues.
• D. X-ray rooms exhibit increased signal attenuation.

Correct answer: D

Explanation

The correct answer is D, as X-ray rooms are designed with materials that can absorb or block signals, leading to increased signal attenuation. Options A, B, and C do not accurately describe the primary issue affecting Wi-Fi connectivity in X-ray rooms, which is mainly due to the physical properties of the room's construction and not interference or multipath effects.
