CompTIA Network+ (N10-008) — Question 194

A Wi-Fi network was originally configured to be able to handle interference from a microwave oven. The microwave oven was recently removed from the office. Now the network administrator wants to optimize the system to maximize the range of the signal. The main sources of signal degradation are the numerous cubicles and wooden walls between the WAP and the intended destination. Which of the following actions should the administrator take?

Answer options

• A. Implement CDMA.
• B. Change from omni to directional.
• C. Change the SSID.
• D. Change the frequency.

Correct answer: D

Explanation

Changing the frequency can help in optimizing the Wi-Fi network to overcome obstacles like cubicles and wooden walls by selecting a band that provides better penetration. The other options, such as CDMA and SSID changes, do not directly address the issue of signal degradation caused by physical barriers. Switching from omni to directional antennas may improve focus but does not solve the underlying frequency-related issues.
