Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 106

An engineer is performing an AP-on-a-stick survey and finds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)

Answer options

• A. Raise the minimum data rate to 24 Mbps.
• B. Increase AP transmit power to improve the SNR.
• C. Allow the use of UNII-2e channels.
• D. Use directional antennas to limit the coverage area of some APs.
• E. Enable power saving mode.

Correct answer: C, D

Explanation

The correct answers are C and D because allowing UNII-2e channels can provide additional non-overlapping channels, reducing interference. Using directional antennas helps focus the signal and limits coverage areas, which also minimizes overlap. Options A, B, and E do not address channel overlap directly and could potentially create other issues such as increased interference or reduced performance.
