Network Troubleshooting Flashcards
What are the basic steps in network troubleshooting?
Identify the problem, establish a theory of probable cause, test the theory, establish a plan of action, implement the solution, verify full system functionality, and document findings.
What tools are commonly used for testing network cables?
Cable testers, tone generators, loopback plugs, and multimeters.
What are common causes of network latency?
High traffic, bandwidth limitations, hardware issues, configuration errors, and distance.
What are common causes of network connectivity issues?
Incorrect IP configuration, faulty cables, hardware failures, DNS issues, and misconfigured firewalls.
What are common issues in wireless networks and how can they be resolved?
Interference, signal strength, channel overlap; resolved by changing channels, upgrading hardware, repositioning devices, and using repeaters or extenders.
What are the uses of traceroute and ping in network troubleshooting?
Traceroute tracks the path packets take to reach a destination, identifying points of failure, while ping checks the availability and response time of a networked device.
What is the purpose of a loopback test?
To test the functionality of network interfaces and cables by sending a signal back to the sender.
