Intermediate level project

Multi-VLAN Office Network in Packet Tracer

Design and build a simulated office network in Cisco Packet Tracer with at least three VLANs, inter-VLAN routing, DHCP, DNS, NAT to the internet, wireless access and a file server, then test and document it.

Deliverables

  • An addressing and VLAN plan with subnet calculations
  • A working Packet Tracer file
  • A test plan with results (connectivity, isolation, services)
  • Configuration documentation and a network diagram

Assessed on

  • Subnets are correctly sized and calculated
  • VLANs, routing, DHCP, DNS and NAT work as designed
  • Isolation and access rules behave as intended in tests
  • Documentation lets another technician understand and rebuild the network
