Topic: Designing a Global Network Infrastructure for Toyota Company's Expansion

Task details:

Toyota Company, a prominent Japanese enterprise headquartered in Tokyo, is experiencing rapid growth and aims to expand its business globally, including cities within Japan and Sydney, Australia. As an IT specialist, your task is to design and implement a robust network infrastructure to support Toyota Company's

ambitious expansion plans. This assignment challenges you to address various technical and security challenges while adhering to industry best practices in networking and cybersecurity.

Task $1$: Network Topology Design for Global Expansion

Your first task is to design a scalable and efficient network topology that connects Toyota Company's headquarters in Tokyo with its branches in Kyushu, Hokkaido, and Sydney, Australia. Consider factors such as inter$-$branch communication, Internet connectivity, and ease of management. You are required to provide a detailed network diagram and rationale for the chosen topology.

Task $2$: Subnetting and IP Addressing with VLSM

Using Variable Length Subnet Masking $($VLSM$),$ allocate IP addresses to each branch's LAN, servers, and links. Incorporate the provided IP address ranges and subnet the addresses efficiently to accommodate the different user sets. Ensure seamless connectivity between Tokyo, other Japanese cities, and Sydney. Your

design should maximize IP address utilization while allowing for future growth.

Note: Your IP address allocation and subnetting should align with the given student ID digit sets $($Set

$1$ to Set $5).$

There are $5$ sets of user allocations for this scenario:

Set $1$:

Tokyo building $(37000$ users$),$ Kyushu building $(25000$ users$),$ Hokkaido building $(17000$ users$)$ and Sydney

building $(14200$ users$)10\mathrm{.}16.$XY$\mathrm{.}0/8$

Set $2$:

Tokyo building $(42000$ users$),$ Kyushu building $(26000$ users$),$ Hokkaido building $(19000$ users$)$ and Sydney

building $(16200$ users$)$ with the private IP address of $10\mathrm{.}32.$XY$\mathrm{.}0/8$

Set $3$:

Tokyo building $(53000$ users$),$ Kyushu building $(12000$ users$),$ Hokkaido building $(18700$ users$)$ and Sydney

building $(6300$ users$)$ with the private IP address of $10\mathrm{.}43.$XY$\mathrm{.}0/8$

Set $4$:

Tokyo building $(92000$ users$),$ Kyushu building $(33000$ users$),$ Hokkaido building $(19200$ users$)$ and Sydney

building $(17400$ users$)$ with the private IP address of $10\mathrm{.}65.$XY$\mathrm{.}0/8$

Set $5$:

Tokyo building $(36600$ users$),$ Kyushu building $(20600$ users$),$ Hokkaido building $(18320$ users$)$ and Sydney

building $(16725$ users$)$ with a private IP address of $10.110.$XY$\mathrm{.}0/8$

There are $5$ sets of IP addresses.

$$ For those students who have the last digits of student ID $0$ or $5($Set $1)$

$$ For those students who have the last digits of student ID $1$ or $6($Set $2)$

$$ For those students who have the last digits of student ID $2$ or $7($Set $3)$

$$ For those students who have the last digits of student ID $3$ or $8($Set $4)$

$$ For those students who have the last digits of student ID $4$ or $9($Set $5)$

Note: XY is the last $2$ numbers in your student's ID$.$
