About this course

A structured method for network faults: models, hypotheses and evidence; connectivity and path tools; physical and layer-2 faults; addressing, DHCP and DNS; performance (latency, loss, MTU, TCP window limits); packet capture and analysis; documentation, user communication and a runbook project.

Academy-authored content.

Course highlights

  • Apply a structured troubleshooting method: define, gather evidence, hypothesise, test, fix, verify, document
  • Isolate physical, layer-2 and addressing faults with the right tools
  • Diagnose DHCP, DNS and application-reachability problems
  • Measure and explain performance problems: latency, loss, MTU and throughput limits
  • Capture and analyse traffic responsibly and communicate findings
