CompTIA DataX (CNX-001) — Question 9

A network administrator recently deployed new Wi-Fi 6E access points in an office and enabled 6GHz coverage. Users report that when they are connected to the new 6GHz SSID, the performance is worse than the 5GHz SSID. The network administrator suspects that there is a source of 6GHz interference in the office. Using the troubleshooting methodology, which of the following actions should the network administrator do next?

Answer options

• A. Test to see if the changes have improved network performance.
• B. Use a spectrum analyzer and check the 6GHz spectrum.
• C. Document the list of channels that are experiencing interference.
• D. Change the channels being used by the 6GHz radios in the APs.

Correct answer: B

Explanation

Using a spectrum analyzer to check the 6GHz spectrum is crucial for identifying the source of interference, making option B the correct choice. Testing for performance improvements (option A) and documenting interference (option C) are important steps, but they do not directly address the immediate need to diagnose the interference. Changing the channels (option D) may help but should be based on evidence gathered from the spectrum analysis.
