CompTIA Network+ (N10-008) — Question 20

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?

Answer options

Correct answer: D

Explanation

The correct answer is D, the Spectrum analyzer, as it can detect interference from other wireless networks and non-802.11 devices by analyzing the radio frequency spectrum. The other options, such as NetFlow analyzer, Bandwidth analyzer, and Protocol analyzer, focus on traffic analysis and bandwidth usage rather than identifying RF interference issues.
