Network Administration and Troubleshooting

Networks are blamed for every problem nobody else can explain, and an administrator who cannot prove otherwise spends their career on other people's faults. This course builds that capability. Delegates work through addressing, subnetting and routing to the depth daily work requires, switching, virtual networks and the spanning tree behaviour that causes intermittent faults, and wireless deployment and interference. Services that everything depends on are covered: name resolution, address assignment and time. Structured troubleshooting is the core of the course, working from the symptom through layers to evidence rather than by guesswork. Monitoring, capacity and documentation follow. The course closes on change control and on the outages caused by a change nobody recorded.

Course objectives

  • Apply addressing, subnetting and routing to daily work
  • Configure switching and virtual networks, and diagnose loop behaviour
  • Deploy wireless and diagnose interference and coverage problems
  • Administer name resolution, address assignment and time services
  • Troubleshoot from symptom through layers using evidence
  • Monitor capacity and document a network usefully
  • Apply change control so outages can be traced to a cause

Who should attend

  • Network administrators and technicians
  • IT support and infrastructure staff
  • System administrators with network responsibility
  • Security staff needing network fundamentals
  • Technicians moving into network roles
