Question 1

In an 802.11n 2.4 GHz BSS, what prevents each station fromusing the full network bandwidth (e.g. 130 Mbps) for user data throughput when multiple clients are actively exchanging data with the AP?

A. WLAN devices cannot detect collisions and must receive positive frame acknowledgment. B. Radio receiver hardware cannot process data as quickly as it can be transmitted. C. Half of the bandwidth is allocated to uplink traffic and half to downlink traffic. D. APs do not have sufficient wired connection speeds to the LAN, even at 1 Gbps connections with 802.11n and earlier APs.

Question 6

What advantages does using predictive site survey modeling software offer over performinga manual site survey? (Choose 2)

A. Predictive modeling software provides more reliable data than manual surveys when fine-tuning and validating access point placement after the installation. B. Predictive modeling software makes it simple to assess multiple different AP locations and then adjust and display the AP's expected coverage pattern in almost real-time. C. It takes less time to create an initial site survey for a large facility when using predictive modeling software than when performing a manual survey. D. The exact impact of interference sources from external networks can be more accurately measured when using predictive modeling software than with manual surveys. E. Predictive modeling software can predict the ideal access point location 100% of the time, whereas the results from manual surveyingare less reliable.
