CWNA: Certified Wireless Network Administrator v107 — Question 41

What statement about 802.11 WLAN performance is true?

Answer options

• A. In modem networks, both centralized and distributed data forwarding work well for most standard office deployments
• B. In most WLANs, no special skill or tuning is required to get peak performance
• C. WLANs perform better as more wireless clients connect with each AP
• D. To get the best performance out of an AP, you should disable data rates of 72 Mbps and lower

Correct answer: D

Explanation

The correct answer is D because disabling lower data rates helps reduce interference and increases overall throughput. Option A is incorrect as the effectiveness of data forwarding methods can vary based on the specific network design. Option B is misleading because while some WLANs may work well out of the box, optimal performance often requires tuning. Option C is false since performance can actually degrade with too many clients connected to a single AP.
