The correct answer is B. Evaluate the client's operating frequency band with a spectrum analyzer, looking for a high noise. See the full explanation below for the reasoning.
Question
You have been sent as a consultant to a customer site that is experiencing problems with some 2.4 GHz clients on their 802.11a/g/n/ac network. After collecting information from the company about the problem, your initial troubleshooting step is to find a client device experiencing performance problems and observe its 802.11 frame exchanges in a protocol analyzer. The retransmission rate for that client is 65% instead of the company's baseline, which is 9%. Based on this information, what troubleshooting step should follow to isolate the problem?
Options
- ACheck the frame decodes in the protocol analyzer and look for an excessive number of
- BEvaluate the client's operating frequency band with a spectrum analyzer, looking for a high noise
- CUtilize a laptop-based site survey and planning tool to create a predictive model of the optimal AP
- DWith a protocol analyzer, identify the client's roaming threshold settings and reassociation
- EInstall Wi-Fi endpoint security and reporting software on the client device to monitor and log the
