CompTIA Network+ N10-005: 2.1 – Port Mirroring

Switched networks provide direct communication between devices, but this can be a problem when you need to troubleshoot network traffic flows. In this video, you’ll learn about port mirroring and how to use port mirrors to copy traffic to your network troubleshooting devices.

CompTIA Network+ N10-004: 5.3 – Hardware Tools

If you’re managing a network, you’ll need a comprehensive toolkit to keep things running at peak efficiency. In this video, you’ll learn about the tools that will make your life a much better place. We’ll discuss cable testers and certifiers, TDRs, multimeters, punch-down tools, voltage event recorders, and much more.

CompTIA Network+ N10-004: 5.2 – Network Scanners

The network is a constantly moving river of information, and it may be necessary to occasionally test the water as it flows by. In this video module, you’ll learn the reasons for scanning your network and the different technologies available to gather information. We’ll also dive into packet analyzers, intrusion detection systems, intrusion prevention systems, and port scanners.

CompTIA Network+ N10-004: 4.4 – Network Monitoring

The world of network monitoring is a precise science, and it can provide insight into aspects of network performance that would otherwise go unseen. In this module, you’ll learn the use of network analyzers, connectivity software, and load testers to help build a more efficient network. You’ll also learn the value of logs and how the consolidation of logs files can assist in solving issues that span multiple devices.
