Overview
Network mystique causes thrash. You learn to verify link lights, interpret port descriptions, capture harmless switch summaries, and escalate with structured data. Exercises stay away from carrier core topics and focus on campus edge patterns common in private schools.
What is included
- Port description reading marathon with real-looking configs
- DHCP lease timeline storytelling for leadership
- Guest vs staff SSID intent mapping
- Cable tester drills and tone etiquette in occupied halls
- Warm transfer paragraph for external vendors
Outcomes
- Produce a clean escalation bundle after thirty minutes of triage
- Explain VLAN intent to a principal using a simple diagram
- Avoid destructive testing on live uplinks

Common questions
Do we configure production switches?
Only isolated lab stacks with wiped configs. No remote access to partner networks.
Math depth?
Subnet math is introduced gently with calculators allowed; focus is operational literacy.
Not covered?
Carrier BGP and data center design are explicitly excluded.
