Simple Company Networking
WTX Company, a fast‑growing food trading business in Eastern Australia with over 2 million customers globally, plans to open a new branch near Bonalbo. The company needs IT graduates to design a separate network for this branch.
The branch network must use one Cisco router and one Cisco switch to create three VLANs (IT, HR, Reception), each with its own wireless access and devices receiving automatic IPv4 addresses via DHCP. All departments must be able to communicate across VLANs, and the design should use the 192.168.1.0 base network with appropriate inter‑VLAN routing.
Hotel Management Networking
You must design and implement a multi‑floor network for Alex Modern Hotel, where the first floor has Reception, Store, and Logistics, the second has Finance, HR, and Sales/Marketing, and the third hosts IT and Admin. The network design should consider departmental connectivity, appropriate hardware, and overall infrastructure layout across the three levels
