Description

Knowing the tools available to troubleshoot networks makes solving network issues much easier. This course will teach you about important tools network technicians and engineers use to troubleshoot network issues.

What You'll Learn?

Understanding potential network issues allows a network technician to rule out possible theories of probable cause more quickly. Understanding the tools available to help isolate these potential network issues, allows the technician the ability to test any theories. In this course, Network Troubleshooting: Common Issues and Solutions for CompTIA Network+, you’ll learn to use network troubleshooting tools to isolate potential issues. First, you’ll explore performance issues with wired and wireless networks. Next, you’ll discover software tools available to a technician including tcpdump, Wireshark, nmap, and netstat. Finally, you’ll learn how to issue commands to better understand network hardware functions. When you’re finished with this course, you’ll have the skills and knowledge of troubleshooting data networks needed to use appropriate tools to troubleshoot data networks.
