Troubleshooting High Jitter in Wireless Networks
Question
A technician receives feedback that some users are experiencing high amounts of jitter while using the wireless network.
While troubleshooting the network, the technician uses the ping command with the IP address of the default gateway and verifies large variations in latency.
The technician thinks the issue may be interference from other networks and non-802.11 devices.
Which of the following tools should the technician use to troubleshoot the issue?

A. B. C. D.D.
The best tool for troubleshooting wireless network issues caused by interference from other networks and non-802.11 devices is a Spectrum analyzer, so the correct answer is D.
A Spectrum analyzer is a tool that measures and analyzes the frequency spectrum of wireless signals, identifying the sources of interference, such as other wireless networks, cordless phones, Bluetooth devices, microwave ovens, and other non-802.11 devices that operate in the same frequency range. It can help the technician determine the strength and frequency of the interfering signals and adjust the wireless network settings accordingly to avoid or minimize interference.
A NetFlow analyzer (A) is a tool that collects and analyzes traffic data from routers and switches, providing visibility into network traffic patterns and helping to identify issues such as network congestion or security threats. While it can be useful in troubleshooting some network issues, it is not specifically designed to diagnose wireless interference issues.
A Bandwidth analyzer (B) is a tool that measures the amount of bandwidth used by different applications and devices on a network, helping to identify bandwidth-intensive applications and bottlenecks. It can help identify network performance issues, but it is not designed to diagnose wireless interference issues.
A Protocol analyzer (C) is a tool that captures and analyzes network traffic at the packet level, helping to identify issues with specific protocols, such as TCP/IP or HTTP. While it can be useful in diagnosing some network issues, it is not specifically designed to diagnose wireless interference issues.
Therefore, the best tool for troubleshooting wireless network issues caused by interference from other networks and non-802.11 devices is a Spectrum analyzer (D).
