Which of the following items could be considered constraints when performing a network design?(Choose all that apply.)
Assume that your network operates in a regulatory domain that allows use of the entire 5 GHz space allowed in the 802.11ac amendment. In your
upcoming
802.11ac deployment, you would like to take advantage of the performance improvements that result from channel bonding. However, after
extensive testing, you have determined that your mission-critical WLAN should not use channels requiring DFS support.
Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how many non-overlapping 40 MHz channels
will your system be able to use?
Given: You are evaluating the theoretical and real-world RF gain benefits of transmit and receive features introduced by 802.11 with MIMO. This
exercise allows you to quantify the features value in a real-world environment.
What is the maximum theoretical signal gain of chip-based TxBF and MRC (as features) when compared to the same AP using only a single
antenna for transmit and receive (effectively simulating a 1x1 chip)?
The maximum theoretical signal gain of chip-based TxBF and MRC depends on the number of antennas and the channel conditions. TxBF (transmit beamforming) is a technique that focuses the transmitted signal in the direction of the intended receiver, resulting in higher signal strength and less interference. MRC (maximum ratio combining) is a technique that combines the signals received by multiple antennas in an optimal way, resulting in higher signal-to-noise ratio and better performance. The theoretical gain of TxBF and MRC can be calculated as
GTxBF=10log10(N)
and
GMRC=10log10(N)
where N is the number of antennas. Therefore, the total gain of TxBF and MRC is
Gtotal=GTxBF+GMRC=20log10(N)
However, this is the ideal case and assumes perfect channel conditions and alignment. In reality, the gain is lower due to factors such as channel fading, antenna spacing, and feedback delay. According to the CWDP study guide1, the typical gain of TxBF and MRC is about 4-6.5 dBi for 2 antennas, 7-10 dBi for 3 antennas, and 10-13 dBi for 4 antennas. Therefore, the answer is D.

During a post-validation assessment, you have configured a client for 802.1X/EAP but it is not passing authentication. Which areas should you check in the WLAN configuration?
