Which tool is used to monitor live network traffic for troubleshooting? Learn how packet sniffers like Wireshark capture and analyze real-time data packets, essential for Cisco Certified Support Technician (CCST) Networking 100-150 exam success.
The correct tool for monitoring live network traffic for troubleshooting is a packet sniffer.
A packet sniffer is a network analysis tool that captures and inspects data packets as they travel across the network in real time.
Popular packet sniffers include Wireshark and Tcpdump, which allow technicians to view detailed information about each packet, including source and destination addresses, protocols, and payload data.
By analyzing captured packets, technicians can identify issues such as network congestion, packet loss, latency, and misconfigurations, making packet sniffers invaluable for troubleshooting and optimizing network performance.
Packet sniffers provide visibility into network behavior, help detect anomalies, and support deep inspection of traffic flows for both security and operational diagnostics.
Ethical use is important: packet sniffing should only be performed with proper authorization to avoid privacy and legal issues.
A packet sniffer captures and analyzes live network traffic, making it the essential tool for troubleshooting and diagnosing network issues in real time.
