Cybersecurity and ITNetwork 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.
