Some of the most common tools and techniques used by network administrators during troubleshooting include ping, traceroute, packet capture, and system logs.

Ping is a basic network troubleshooting tool that tests network connectivity between two hosts.

It sends a “ping” packet to the host and waits for a response. If a response is received, the connection is good and can be used for communication.

Traceroute is another network troubleshooting tool. It determines the path that data takes to reach a destination. A packet capture is when the network traffic is recorded in real time for analysis.

System logs capture system messages, errors and other events that can help diagnose and troubleshoot network problems.

Network Maintenance:

Network maintenance includes evolving
procedures for monitoring and managing network performance, security, and reliability. This involves regular backups and system updates, monitoring of network health and performance, and troubleshooting any anomalies.

Other Network Maintenance Tools and Techniques:

Other commonly used maintenance tools and techniques include network analysis tools, proactive monitoring, and automated patching.

Network analysis tools are used to analyze the traffic on the network, detect any problems, and recommend corrective action.

Proactive monitoring is used to detect any threats or intrusions and to take action before they become major problems. Automated patching keeps the network up-to-date with the latest software updates.


Network maintenance is an important part of keeping a computer network reliable, secure, and efficient.
