Introduction
Ethernet LAN for the given scenario will be designed. Suitable network designing software will be selected. Suitable network devices will be selected. Suitable network connecting media, IP Addressing, DHCP Settings, Router settings and firewall settings will be done.
Cisco Pocket Tracer Design
The Cisco Packet Tracer design file is attached.
Cisco Pocket Tracer file is shown above. Only LABS are shown. Offices are not shown due to space restrictions. Assume that one firewall and one wireless router is used for all the labs and offices.

Static IP Assignation
All servers will be having static IP addresses.
Here all the PCs are using DHCP for IP assigning. In LAN the default gateway will be in the same network. i.e 10.109.150.1 will be the default gateway for all the devices in LAN.
Cat6 cables can be used for wired networking
811.n technology can be used for wireless networking.
Conclusion
Ethernet LAN for the given scenario is designed. Suitable network designing software is selected. Suitable network devices are selected. Suitable network connecting media, IP Addressing, DHCP Settings, Router settings and firewall settings are done.
