Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 115

A network consultant must create a wireless design with these characteristics:
• Provide coverage in a single contiguous space.
• Support dual-band wireless coverage.
• Use nine APs for full coverage in a 5 GHz band.

What must the engineer do to mitigate co-channel interference and maintain coverage in 2.4 GHz?

Answer options

• A. Adjust the TPC neighbor threshold value to -64 dBm on the 2.4 GHz band.
• B. Configure static channel and power settings of the 2.4 GHz radios.
• C. Disable 2.4 GHz radios on selective APs.
• D. Deactivate low data rates on the 2.4 GHz band.

Correct answer: C

Explanation

The correct answer is C because disabling the 2.4 GHz radios on selective APs helps to minimize co-channel interference by reducing the number of active devices on the same frequency. Options A and B do not effectively address interference issues, while option D would not solve the coverage requirement in the 2.4 GHz band.
