From foundational knowledge to evidence-driven network engineering.
Trace packets across switching and routing, investigate campus VLANs, OSPF, NAT/PAT, wireless, ACLs, monitoring and safe change management, then resolve an integrated Northstar campus and branch incident.
You can open any step at any time. Mark activities complete when you're satisfied you've learned or practiced them—there are no locked lessons.
This applied path assumes the addressing, DHCP/DNS, MAC forwarding, VLAN/trunk and STP fundamentals taught there. If you have not practiced them, start with Foundations; otherwise move straight into evidence-led diagnosis.
Use route, neighbor, DNS/transport and dual-stack evidence to isolate problems along an end-to-end packet path; assumes Networking Foundations.
Four new evidence-driven cases spanning neighbor failures, dual-stack routing, TLS and application responses.
Revisit any resource as often as you need. Completion is a personal reminder, not an exam score or verified certificate.
