What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag?(Choose all that apply.)

What advantage provided by 802.11n and 802.11ac is not usable in 1X1:1 low-end client devices?
Response:

For what types of systems should you request read-only access to in order to perform an analysis of the customer's existing infrastructure?(Choose all that apply.) Response:

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)?

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure.
What should you do to prevent this?
