Câu 9: CWAP-405: Certified Wireless Analysis Professional

You are troubleshooting an intermittent problem with some WLAN VoIP phones resulting in dropped calls. You configure your capture on a fixed channel matching the current operating channel of a test phone. So far, you have been unsuccessful in capturing the problem because the VoIP phone always roams to another AP before the problem occurs. What would be the best setup for your packet capture to make sure you capture the problem?

1. A. Determine which channel the phone is likely to roam to next and capture on that channel.
2. B. Configure the capture adaptor to scan all channels used in the environment.
3. C. Configure all APs in monitor mode and have the packets streamed back to your analyzer.
4. D. Use multiple capture adaptors and the channel aggregator feature of a protocol analyzer to capture on all AP channels in the client’s area. — đáp án hiện tại
