Designing Cisco Wireless Enterprise Networks (WIDESIGN, legacy) — Question 30

A hospital environment was designed to guarantee RF coverage at or better than -67 dBm in the 5 GHz spectrum. The customer mandates that RRM be used for
DCA and TPC in both bands. After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?

Answer options

• A. Excessive co-channel interference in the 2.4 GHz band exists.
• B. Excessive overlapping channels in the 2.4 GHz band exists.
• C. TPC drastically reduces Tx power in the 2.4 GHz band.
• D. TCP drastically increases Tx power in the 2.4 GHz band.

Correct answer: D

Explanation

The correct answer is D because TCP is not a power control mechanism; therefore, it does not directly influence transmission power. The other options focus on interference and channel overlap, which can affect connectivity, but they do not specifically address the power management issues caused by TCP configurations.
