出題：7

Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere with each other when they transmit frames. Assuming no other APs are in the vicinity, is CCI still a possibility in this network and why?

A. No, because CCI only occurs in the 5 GHz frequency band.

B. Yes, because channel 11 loops around and causes CCI with channel 1.

C. No, because the APs are far enough apart that no CCI will occur.

D. Yes, because the client devices connected to one of the channel 1 APs will transmit frames that reach the other channel 1 AP as well as clients connected to the other channel 1 AP.

What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?

A. OFDM modulation is used only in 5 GHz 802.11 transmissions.

B. OFDM was first introduced in 802.11a and is used by the ERP, HT and VHT PHYs as well.

C. OFDM implements BPSK modulation to allow for data rates up to 7 Gbps.
