Question
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?
Options
- ATest to see if the changes have improved network performance.
- BUse a spectrum analyzer and check the 6GHz spectrum.
- CDocument the list of channels that are experiencing interference.
- DChange the channels being used by the 6GHz radios in the APs.

Explanation
Standard troubleshooting methodology follows: identify the problem → establish a theory → test the theory → establish a plan → implement → verify → document. The administrator has already identified the problem (poor 6GHz performance) and formed a theory (interference). The next step is to test that theory, which means using a spectrum analyzer to examine the 6GHz band and confirm whether interference actually exists and where it originates. Testing (A) comes after a solution is implemented. Documenting affected channels (C) and changing channels (D) come after the root cause is confirmed - acting before verifying interference would be skipping a step in the methodology.
