create a site map for an ethernet LAN with the given project information Context and Scenario: GlobalTech Solutions, a renowned player in the semiconductor industry, is located in Sydney and is known for its advanced wireless technologies like Wi$-$Fi and Bluetooth, serving a wide range of modern devices. The company's headquarters are spread across two buildings: the first hosts the Administration group and Customer Service office, while the second houses the Sales, Marketing, and Research and Development groups.

Objective: To design and implement a robust Ethernet LAN to accommodate the company's projected $10\%$ growth over the next $5$ years. The project involves a practical approach to network design, documentation, and prototype development to ensure functionality and efficiency.

Design Requirements:

Departments and Employees:

Research and Development: $32$ employees

Sales and Marketing: $20$ employees

Administration: $12$ employees

Customer Service: $6$ employees

Each floor space is $30$ m by $16$ m$.$ It is up to you how you wanted to design the space providing any assumptions you have made. You need to have a minimum of $1$ reception office, $1$ manager office, $1$ meeting room, and remaining shared office space. Consider network equipment rooms, common areas $($meeting rooms, break rooms etc$)$

Network Setup:

Each department requires at least two networked printers.

Adhere to CISCO's three$-$layer hierarchical design model.

Distinct IP sub$-$network for each department.

Internet and main network connectivity via FastEthernet fiber optic link $(100$Base$-$FX$).$ Default gateway is $192\mathrm{.}168\mathrm{.}40\mathrm{.}39.$

Class B network: $189.$A$0\mathrm{.}0$A$\mathrm{.}0/24($A $=$ last digit of a group member$$s student ID$).$
