This network design assignment creates a secure, scalable network for a 50-person office. The design includes a hierarchical topology with core, distribution, and access layers. The core layer uses redundant switches for high availability.
IP addressing uses a Class B private range (172.16.0.0/16) subnetted into /24 networks per department (Finance, HR, Engineering, Guest WiFi). VLANs isolate traffic between departments. Inter-VLAN routing occurs at the distribution layer.
Security measures include ACLs restricting Finance VLAN access, port security on access switches, and a firewall between the internal network and internet. The wireless network uses WPA2-Enterprise with RADIUS authentication. All configurations are documented with Cisco IOS commands.
