Network Engineering & CCNA Bootcamp Certificate

Checkpoint 1: Build a multi-router/multi-switch Packet Tracer topology; document addressing plan, subnet calculations, VLAN boundaries, trunks and expected Layer 2/3 forwarding paths.
Checkpoint 2: Configure VLANs, trunks, inter-VLAN routing and spanning tree; create a loop or VLAN mismatch intentionally, diagnose the symptom and show the exact control-plane fix.
Checkpoint 3: Configure static routes and single-area OSPF; validate neighbor formation and route tables, then break adjacency or path selection and troubleshoot from CLI evidence.
Checkpoint 4: Implement DHCP/DNS-adjacent service assumptions, standard/extended ACL policy and NAT/PAT at the edge; prove permitted and denied flows with packet-level reasoning.
Checkpoint 5: Design a small wireless LAN with channel/security choices and integrate it into the routed network; document RF/security assumptions and test client connectivity.
Checkpoint 6: Add an automation artifact using structured data/API or configuration templating; collect device state, compare intended vs actual configuration and produce an operations runbook.

Day 1: Choose a branch/campus scenario; draw topology, VLANs, IP/VLSM plan, routing domains, redundancy goals, security policy and acceptance tests.
Day 2: Build switching: interfaces, VLANs, trunks, EtherChannel/STP where appropriate; validate MAC tables and deliberately troubleshoot one Layer 2 fault.
Day 3: Build routing: static/default plus OSPF; verify adjacencies and paths, then diagnose one broken route, neighbor or addressing condition.
Day 4: Add services/policy: DHCP assumptions, ACLs, NAT/PAT, device management and secure remote access; prove allowed/blocked traffic from test cases.
Day 5: Add wireless and resiliency/operations considerations; capture Packet Tracer or CLI evidence for connectivity, segmentation and fail/recovery behavior.
Day 6: Create an automation/state-check script or API workflow for inventory/config validation; compare intended state with device output and flag drift.
Day 7: Publish topology, configs, subnet worksheet, test matrix, troubleshooting diary, automation artifact, demo video and a concise network operations runbook.
